I'd like to replace my muffler with a slightly louder/throatier/Flowmaster sound and also replace the rusty tailpipe. I haven't been able to find a replacement other than a Walker system that is labeled "quiet flow" (not what I'm looking for). Is there another system out there? Or do I have to buy a muffler separately and have a muffler shop bend a custom tailpipe to fit?
-
There aren't any aftermarket exhausts, you're going to have to buy a muffler and have a shop install it. In the end it usually works out cheaper than it is to buy an aftermarket exhaust for other makes/models
-
Thanks. How do I find one? I've looked on the Flowmaster and Dynamax websites but nothing is available for our cars.
-
You'll have to measure the stock muffler (or find OE measurements online, rockauto might help?) and punch those measurements & inlet/outlet configurations in and see what pops up.
I'd recommend going to a slightly larger pipe as an upgrade
-
Dynomax turbo muffler 2" inlet/outlet w/offset outlet, sounds sick on this car. Noticeably louder than factory without being obnoxious. I have no cat.
-
I have a cat back exhaust, moving up to a custom 21\4 this weekend,
-
What size is the current exhaust? 2"? If I go with a slight larger pipe (2.5", I guess), where does this start? After the exhaust (tailpipe) or before the exhaust?
-
In a perfect world you'd want to replace every bit of pipe on the car to open it up.
Most folks go for a Cat-Back exhaust to start. The stock exhaust is 1 7/8" OD IIRC, not even 2"
2" ID would be a upgrade. I would NOT do 2.5" on a non-turbo engine. It'll be too loud, and you'll notice a loss of power. Mandrel bent piping is ideal but most shops don't have a bender, personally I buy mandrel bends online and then piece my systems together.
Once you do a cat-back, you can upgrade the downpipe and get a high-flow cat (or delete the cat if your locality doesn't have emissions) Some folks do this all at once, depends on your budget.
-
Thank you. Is the resonator reused if you do a cat-back upgrade of do you just get a shop to install a 2" ID pipe from the cat to the new muffler?
Reed - do you have a resonator?
-
You can use a new resonator or just do without. Most I've seen do without
-
I just got a quote of $1,200 to do complete exhaust system replacement. Seems a bit stout to me. For that $$ I may learn how to weld.
-
That sounds about right for a custom mandrel bent TIG welded stainless steel system with premium everything... it shouldn't run much more than $250-300 for a generic mild steel system. Shop around some more :D
I picked up a cheap welder & started welding my own exhaust systems, I buy mandrel bends online. Works for me
-
I figured something north of $200 and south of $300 was to be expected. I have to have a cat, but it looks like even those can be had for $50. Glasspack. should be able to do something in the $250 neighborhood.
Thanks once more for your insights/help.
