I run 3.6 cans on a 3.4 - even with a hack mod they are very quiet and would make sound spec IMO

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

19 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

I know this has been asked before. But I need to borrow a set of stock mufflers for laguna seca next weekend. My friend has his stock ones from a 2003 c4s he can let me borrow. Will these bolt onto my 1999? I do not care about where the tips are since my rear bumper is thrashed anyway. Will these quiet down the car the same as the 3.4 cans would? I am going to be running mufflers and no cats so I need them as quiet as possible.

POST 2Original post

yes they will fit. people hack 3.6L cans for 3.4L engines.

POST 4 / ORIGINAL POSTEROriginal post

I think I might have the 3.4 brackets kicking around somewhere, I'm going to go pick up the 3.6 cans at lunch and hopefully it all fits together. Thanks guys. There was so much talk about hacking them when I searched, but none about making my car quieter. I guess people don't like to mod things to be quieter.

These are not difficult to install, but on my MY00 996, I did have to swap the connector backing plate (number 28, the 3 bolts (16) didn't line up on the car). You just remove the bolts 24 and 25, swap out #28 and you're golden. Also, putting on the tips requires the screwdriver X, which is posted somewhere in detail. The first time, it takes about an hour a side. And a lot of cursing. After that, it's pretty quick. Tim's famous annotated muffler install diagram is posted below for reference. -td

POST 6Original post

I run stock 3.6s cans on my 3.4 and the sound is greatly improved.

POST 7 / ORIGINAL POSTEROriginal post

are they jsut stock? The point here is, I am NOT looking for sound improvement. I am looking for quietness.

POST 8Original post

Quotes source post: 6813357

Yes, just stock from an 03 C4S. Your stock tips will fit just fine.

POST 9Original post

03 C4S mufflers bolted right into my 99 without any changes...

POST 10 / ORIGINAL POSTEROriginal post

unfortunately, I do not have my stock tips. But what I do have is a rear bumper that's already met 1 wall and I really don't care much about.

POST 11Original post

I think you'll make the noise regs without needing real tips!

POST 12Original post

tips dont cut noise, just transfer the exhaust from the muffler to the rear of the the car - and they are only a few inches long..... I run 3.6 cans on a 3.4 - even with a hack mod they are very quiet and would make sound spec IMO

POST 13 / ORIGINAL POSTEROriginal post

Quotes source post: 6813723

I am not running any cats, so that's where the concern comes from.

POST 14Original post

awe ha cotton.... that is your answer... lots and lots of cotton It must suck to have to tone down something you love just for some new rule... I mean its a race track for goodness sake - poeple bought property NEXT TO the race track because why.... it was CHEAP! and why was it cheap.... because it's NOISY... then the biach about the noise and pass laws...

POST 15 / ORIGINAL POSTEROriginal post

It is actually very very expensive land, and the track is owned by the county. And the people that own the land, aside from building next to a noisy track when they like quiet, are pretty smart and were able to cause such rules. The cans fit with the 99 brackets. We haven't put the bumper back on yet, and I haven't heard it yet, but im hoping it works.

POST 16Original post

Quotes source post: 6815466

Why was the bumper off?

POST 17 / ORIGINAL POSTEROriginal post

just more room to work with

POST 18Original post

hmm, no cats - stock mufflers... I think a sound clip is in order here........... how do you run no cats w/o throwing a CEL

POST 19 / ORIGINAL POSTEROriginal post

I have the fabspeed bypass pipes since last fall. Took the mufflers off last winter, and still have not thrown a CEL yet. I'll have in car video from the race to post up.
