Y pipes

[surebimmer]

Well I got the car towed down to the exhaust shop and he's going to use Chevy manifold bracket with dual 2 inch pipes from the manifold to a dual in mangaflow cat with a single 2.5 out with a magnaflow turbo muffler. Going to try that out. If it too loud there will be space to put an resanator before the muffler.

^^ thought you wanted to keep this car quiet :)

after 10k miles and 1 track day I'm ready to make a change :)

So your saying even with the resiantor this setup is going to be very loud? I don't daliy drive my car. It's mostly a track/autox/weekend car.

I personally dont think it will be obtrusive...but it will sound strong, and perhaps even resonate inside car. Did you hear my video?.........2.5 single ...header ..mf cat ..borla turbo....on an m20 tho

Just got the car back from the muffler/exhaust shop. Here are some pictures of what I'm running. OBD 2 tube manifolds, I welded the ports closed but then used a cover from a E90 330i to cover the hole. The cover had to be ground down a little to sit flush. Part number for the cover is 11727511542. Rest is dual 2" into Magnaflow cat to 2.5" single out. With a 18 inch rear Magnaflow muffler. With the sleeper 318i looking tip.

That looks great! How does it sound, and how much did it cost complete? I'm looking to replace the exhaust from the header back on my cabrio and am curious to hear your opinions on your setup.

Cost me $550. It's loud but not too loud. I'll see if I can get a sound clip.

looks good. That's what I'm planning to do, I'd love to hear a sound clip. I am also planning to put in a resonator though up near the Y-pipe, right around where the transmission is.

Video clip with sound is at: http://home.comcast.net/~rj.dk.sanchez/CAR.S52.3gp

Its a cell phone video format that plays in quicktime.

Dude, that sounds awesome. How badly does it resonate in the cab?

You know what I used for a Y pipe? I got a steel single 2.5inlet to dual 2.25 Exhaust tip for $10. Beat that.
