My stock muffler == Shot!

[SkidPlate]

After 83k my stock exhaust has finally given up on me, I can easily put a screwdriver through it...





The front pipes still seem good so I am going to replace the muffler, tailpipe, and add a resonator tip.

I've decided on a MagnaFlow muffler that was the closest to stock size. (this one is actually 2 inches longer with a center outlet) I believe it will fit, lots of room between the rear shock and axle. I hope.

Then I'm going to have the muffler shop, who says they do custom mandrel bent pipes, fab up a tail pipe with a Monza big-bore pencil tip.

This size muffler is only available with 2.5 in/out lets, I figure they can adapt it to the stock 2.25 front pipe. I ordered the Monza tip w/2.5 inlet also, so the tailpipe is increasing a bit.

Your thoughts?... Discuss.

if your going to have some custom bent pipe anyway.. go dual exhaust hehe j/k thats a whole 'nother level of project... im hoping my stock muffler goes soon so i have a way to justify new muffler and tailpipe... heh

i'm no muffler expert but i have heard good things about magnaflow.... for mine i was looking at a dynamax (or dynapro... i forget the name) that is made for a 3.5L monte carlo.. its got 2-1/4 in and 2-1/2" out

Heh yeah, I thought about duals but decided I would rather just stick w/ a single tailpipe and nice tip.

I am mainly concerned about that large Magnaflow I picked out fitting up under there. It should be OK, there seems to be some wiggle room.

Hopefully they can re-use all of the stock mounting points, all seem pretty solid but will need to be cut off the existing muffler and welded to the new one.

Has anyone ever replaced the Rubber in the stock exhaust mounts? I'm sure they are worn out and would benefit from a refresh.

Parts finally arrive (&@%# backorders).


Heading to the muffler shop tomorrow for the install.

please keep sharing the updates, I'm closing in on 90k but the underbelly looks pretty rusty like it lived it's life up north, at least hte wearable items look pretty rusty (thank goodness)
I may have to consider doing the same thing at some point in the future

This looks like a valid solution. I've got a stock muffler problem as well and Isuzu says 3 months and $391.00 for an OEM muffler. Ouch!
