Catalytic Convert and Muffler replacement - Questions

[JAMAS]

I have had an annoying rattle coming from the area of my passenger side catalytic converter(been going on for about 3 years). Upon constant inspection and trial and error, we are pretty confident its the catalytic converter. Definitely not a heat shield.....possitive.

On top of that, the "quiet" muffler that I had replaced the powervault muffler with, is finally going rattley noisey on me after 3 years. This is probably due the the fact that the muffler was just a cheapy needed to quiet the ride before my Son was born.

So.....My questions.

There are several aftermarket catalytic converters out there. Has anyone had any luck (bad or good) with any of them?

Second...
I need to get a quality muffler, probably stainless steal, that will last and will be quiet. My goal is noise level. I like the roar, but my family situation means I have to be quieter. So anything over quiet is a bonus. (performance, etc). Any thoughts on a good one to go with?

I am getting everything installed by Performance Offroad in Kentucky. The shop is awesome and my minor exhaust work is nothing compared to all the cool projects they have going on. I am just glad I found an excuse to go to that shop.

my muffler guy said they are pretty standard and had one sitting on the shelf - put it on in about 15 minutes no idea what brand but it fixed THAT rattle

Don't know where yu are located but American muffler replaced my muffler for $120 lifetime warranty and it is much quieter then the OEM or the custome muffler I had on truck that lasted 18 months.

That sounds like a great one. I definitely want quiet and something that lasts. I am leaning towards a cherry bomb turbo for the muffler

[evillecutter]

had cherry bombs on my firebird and it was anything but quiet

pro model - that could be why - i would really like to hear how the turbo sounds if you go with that model - i know with 13 years on the oem muffler its only a matter of time before im in your same shoes

Since reading the window sticker awhile back, I've been a little baffled about something. According to the sticker, it says the exhaust is stainless steel. Now if in fact that is true, how come they rust out? I know Borla stainless exhausts are warrantied for life, so whats up with our VX's exhaust?

I have the same little rattle at idle, (when cold) I had already come to the conclusion that the sounds were in the exhaust. I have not taken it apart to inspect it all. I do have a aftermarket muffler that will fit (will be louder), Assume that I will be looking at Cat back exhaust, no rust on underside, so the pipe to the engine should be ok.

200,000 miles on mine and replaced the muffler because thats the only thing that rusted out, but now it has true dual exhaust with a nice quiet flow from walker, all by choice all the pipe was still good when the duals were put on.

What is the information on the muffler you went with?

Did you change out your Catalytic converter?


Thats probably the biggest unknown for me right now. I dont know size and fit. I also dont want a CEL to turn on.

I'm curious about the QF Walker myself. Posted about them a few months ago. No one replied. How do they sound compared to stock?

Did you find a single-in/dual-out unit? Two-in/Two-out? Dual mufflers?

Vid would be cool!!!

Here is what I think I am going to go with:


Catalytic Converter:

Muffler:

Any reason I shouldn't pull the trigger on these?

Any concern about replacing the catalytic converter and affecting CEL popping sensors?

I think inlet and outlet is 2.25" on the cat. Should I be looking for 2.5"?
