New Dual catback....

[Cyrk]

Picked her up from the shop lastnight...

The system looks amazing! It is a new 2.5 exhaust from the downpipes into new bungs for all the O2 sensors, high flow Mangaflow cats, with an H pipe all the way back to 2 massive Manganflow mufflers with 4inch slanted cut tips.

At startup and cruising it sounds bad azz, kinda like a grand national with an exhaust! but as soon as you floor it is way to LOUD, New resonators for each side are getting installed Tues. Feel much stronger - more air in much more air out now :) We are thinking 10-15 more HP when i go back and Dyno it, fingers crossed. This was an expensive mod, but the craftsmanship it top notch, great welds no rattling and mean looking and sounding.

Also powder-coated my intake crinkle black to help with keeping the heat down and added a new BBK air filter and moved the FMU around.

Switched from Mobile 1 Synthetics 10w30 to AMSOIL 5w30 too.

We are thinking off adding water injection and machining the larger pulley down to run more boost (7psi) hopefully.

I snapped some pics, sorry it is crappy out today, will take some under the VX when we put on the resonators Tuesday.

OH NO! You have 2 coffee cans sticking out the back of your VX! Are you purcolating VX coffee now or what man?! :p

Heard you story about the backpressure. Man, there had to be another way.

I have been thinking about this for a while now (all summer to be exact). I THINK I may have found a good fab shop here that can run my dual pipes. New speedshop that just opened up and they claim to "do it all" (only been doing my oil changes up to now, haha). Spoke with them about my 30k and my S/C and they said no problem. The techs love my VX so thats a plus. Now.... I just need to think about how much I want to trust them. ALl young techs who are at least have ASE cert, so, we will see. Of course, I just need to come up with some cash. Buying this new house leaves me eating dry leaves from gutters.

Anyone tried running Y pipe from the PV with an S/C?

[XCross69]

Has a similar look to mine, but mine has oval on the slant!! Nice!

[MachineVX]

Nice.

I'd like to have a dual exhaust done next summer.

I'm thinking of getting a unichip and seeing if that will allow me to run more boost.

[Numba1goalie]

Why hasnt anyone tried to fab up a 350Z exhaust or a FX35 or something? I cant stand to see these fart cans on a nice car like the VX. Leave those things for the ricy hondas.

Any sounds clips of any of them?

[Cyrk]

I agree they are a little to big looking... and I am not totally happy until they can quite it down, with the resonators. Getting a chance to drive it today around, it is too loud for me. I am all about better performance and I am now getting nervous that I spent too much money on this and the sound will drive me nuts.

Does anyone have experience with resonators? Will it quite the exhaust down allot?

[XCross69]

Why you want to hear them if you don't like them :confused:

Mine sound nothing like the "ricy" hondas.....

[Numba1goalie]

I just want to hear them ok! Gosh Napolien! ha.

If I were you guys, start trying to listen to the FX35 or G35 or the 350Z's, and tell me that doesnt sound like a beefy mother?

Not only do I contest against the ricy sound, I also dont like the look of some fart can, let alone two, on the back of a vehicle like the VX.

Putting resinators in my experience with fart cans has resulted in a little more tone sound, but also a little bit more raspier.

[Cyrk]

I LOVE the way the Fx's sound. My new exhaust sounds nothing like that.
So based on your experience with resonators I am F'd? great :mad:

Guess I will have to wait and see when they get in and installed on Tues.

[Numba1goalie]

I'd say call around a Infinity wrecking yard and just find a FX exhaust system.

[Joe_Black]

Nice setup, looking forward to the dyno info. You may want to consider ditching the cans and go with Supertrapp mufflers. The sound is different, but in an ominous "What IS that?" kinda way, plus as they have a disc system you can tune it yourself easily by changing the number and type of discs. Instant exhaust tuning while at the dyno or playing with boost. And they have a variety of styles too.

I'd probably go that way myself if I weren't converting to turbo-diesel. ;)

[Maugan_VX]

Looks good except the fart cans.

[Cyrk]

any body got any good suggestions on what kind of mufflers would look good back there instead of these Magnaflow ones? Joe I took a look at the super trapp ones and I not sure I like the look of thoses... I wonder what kind are on the VX02??

An FX35 does have a beautiful sound, has anyone tried this on a VX yet??

[kpaske]

Personally, I think they look really good. However, I haven't been completely thrilled with the sound or performance from my PV2, so anything as loud as that has got to go, in my opinion.

[morgan-tec]

Resonators tend to deepen the tone a little as well as know down the db's a little but not a lot. One thing to remember is that with the S/C you are increasing your compression this WILL make the exhaust louder than a non S?Ced car. At high rpms there is not a lot you can do to quiet it down without adding some restriction on flow. I personally have a lot of experiance with this since i build custom mufflers for all sorts of cars and trucks. I use a diversionary baffle style muffler similar to a flowmaster but i have figured out how to "tune" the tone somewhat by the placment and design of the baffles in the muffler. Normally i build a single in dual out or dual in dual out muffler for a dual setup. This tucks the muffler back into the stock location so pipe routing is not an issue. Back to your problem, i dont think resonators will quiet it down enough, i think you will need different mufflers, but that is just my opinion. If you have any ?s about exhaust specifically please feel free to ask, i have been building these mufflers for about 5 yrs now and i have a lot of experiance in this field. I am actually designing a new two chamber muffler for my soon to be S/Ced Axiom, it will be a litle more mellow than my current mufflers. Ask Moncha about my Axiom and what it sounds like since we share the same engine.

Cyrk - you have probably THE best looking VX I have seen - I hate to tell you this man, but the best looking mufflers back there instead of what you have are....none. Mufflers need to be hidden - only the tip(s) should show.

[Cyrk]

Thanks guys for all your sugesstions... Tues resonators are going on... if that does not mellow it out I am going to have to lop them off and figure out something else... Performance wise it feels like a beast and has a allot more pull now you can tell the motor is really breathing well now with this setup but boy is it loud... to the point I am embarrassed to get on it.

Morgan-tech, can i purchase 2 smaller mufflers from you that might work with this setup? i really want that mellow electronic sounding exhaust - alah FX35. What do your muffler sound like?

[WormGod]

Ah man, Morgan-Tec's destiny is to create a dual output system for the VX. Spread the ZooZoo love. Nobody will ever work on a VX cause they have no idea what in the hell they are. That's why I am forced to find a new speedshop now. Mine is in there today as they look it over and see if it's something they are willing to play with even though it's just in for some fluid changes today. The last speedshop was sold and bought up by somebody who made it a general auto mechanic shop. No more 1/4 mile machines there.

:(

I am very sad. Running out of oprtions....

This was originally posted in another thread but I like this one....


I purchased my setup at 3 different shops. The FlowMaster came from Speed Unlimited ($114.00). The muffler, FlowMaster 50 Series (524562, it's on their website) has one inlet and two outlets. The inlet on the 524562 is offset to keep the installation of the muffler in the stock position. I didn't have to use a "Y" connector or baffler. Because the exhaust is separted inside the muffler chambers, you get the same amount of exhaust out of each outlet and therefore each pipe. The tips (which are Stainless 304 Steel) came from Trick Trucks ($65 ea) and Meineke did the pipes and installation ($80 parts and $175 labor). The pipe from one outlet is straight out the rear of the driver's side and the pipe from the second outlet is routed up and over the rear axle, over and behind the gas tank, between the gas tank and rear wheel, and out the back on the passenger's side. Both pipes fall about 2-3" below the bumper and almost directly under the rear reflectors. I also didn't have to lose my rear tie downs. The noise from the 50 series FlowMaster inside the truck is barely above that of stock at idle or while cruising at highway speed. Only time there's obvious noise is during acceleration. But the sound is so sweet!

I have a Flowmaster 50 series muffler . . . and all the pipes are hidden . . . I love the sound . . . end of story :-)


For Now

[homer]

On my old vx I found a flowmaster muffler gave my trucck a really nice sound and tone. On start up it sounded more like a V8. I had planned on doing custom piping to make the exhaust but my car got totalled in a car wreck. As far as the flowmaster though it made a nice difference even with the stock piping

[Cyrk]

Finally got the exhaust fixed... added 2 Flowmaster mufflers and lopped off the magnaflow coffee cans and added nice clean 3 inch magnaflow tips... will post pics later. Dyno set up for sat. Sounds much better... a nick loud but nice sounding.

[MZ-N10]

its not possible to get the 350z/fx exhaust notes. unless u get the vq motor off one of those cars.....

[Numba1goalie]

I nabbed two 350Z mufflers from a friend if someone want to buy one of the two?

[Cyrk]

Updated pics... much better looking.

Doesn't a stock 350Z use 2 mufflers? Then you'd have only half a system, right?? :confused:

unless u have a dual exhaust system set up we only need 1 muffler....

[morgan-tec]

Looks tons better than before.

[VehiX]

Looks much better Cryk!

I've always enjoyed your VX and watching its progress over the years.

Keep up the good work :cool:

[Numba1goalie]

WOW, it does look a ton better.

Well I was only planning on running one, but maybe I will see how it sounds with two.

[Maugan_VX]

Cyrk,

that looks good man.

thumbs up.

[CrzyFool]

Whad I tell yah? Flowmaster is the way to go . . .

Let me know how it sounds, I might add a second exhaust to my VX, once I fabricate a heat shield for the gas lines on the right side that is.
