Good Folks,

My muffler is toast. It rattles at about 3,000 RPM. The complete replacement of the exhaust system is about $1600US, I am told (I am sure I can do better, but...). I am told I can have a couple new mufflers welded on, no problem. I would like to know the best choice to match the current performance/noise level/look of the OEM mufflers without breaking the bank. This is a 2002 model, so I want to keep her but I am not looking at Fast & Furious glam or cost.

I am sure you guys have many opinions. Keep in mind that I use want to match current performance/noise level/(looks if possible).

Thank you,
Sean

I will google search that and let you know what I find.

Well, you can usually find used oem exhaust for like $150. It will just bolt on, so you can do it yourself.

They are made from 409 stainless steel, so they usually last practically forever. This is the first I've heard of one rusting through.

This is by far your easiest and cheapest solution.

Any model year exhaust bolts on to any year S, however there are some minor differences in how the tips attach. Also minor differences in rear hangers and Helmholtz shape. So best to just get AP1 for an AP1 car, AP2 for AP2, to avpud hassles with the tips fitting.

This is your chance to do the uk mod, before you install the used system you buy. Bring it to an exhaust shop or a welder. Make sure they use stainless steel pipe, and stainless wire in their mig welder.

To install the new system, get back of car safely up on stands. Unbolt that U channel beam back by the diff. Unbolt the exhaust from the back of the cat. Spray all the rubber hangers with Silicone spray, so they slide off their pins easily. Put a jack under the exhaust to take the weight off. Undo all the rubber hangers. Look at where the hangers are on the new system you are going to install, so you know you got them all. Lower the jack, pull out old, reverse with new.

If you don't want to get your hands dirty, any shop, exhaust or otherwise, should be able to do this install easily in under an hour. So hour of shop labor.

Well, it rattles. The assumption is rust, but it moves when shaken. If I can find an AP1 (2002, right), I will do that. What does the UK mod do?

Thank you,

Have you looked at the heatshields?

Maybe its a broken catalyst? Is your check engine light on, per chance?

Definitely the muffler. Had it up on a rack and checked out. They offered to weld a couple small mufflers to it, but I have no idea how well they work. That is why I am trying to find the best solution.

You're better off just buying a used stock catback locally and slapping it on.

exhaust shop mufflers may not look or sound the greatest.

Hmmm, are you sure the system you have now is stock?

Welding a couple of mufflers on is a hack, and will lower the value of your car (its no longer stock, yet its not a performance mod). It will also cost more than just bolting on a used stock system.

The uk mod is adding a partial bypass pipe to the muffler, for enhanced aural experience. It sounds good. Its just a short section of pipe welded in to the front of each muffler, where the loop is. They cut a hole in both pipes, and splice in the bypass pipe.

The size of the pipe controls how much more sound. People have done everything from 25mm to 48mm or more. The smaller sizes sound like a factory performance system might have sounded like. The larger sizes can be more like an aftermarket exhaust (loud).
