I had a non resonated X pipe before and it was loud around town and a bit too raspy.

This new set up with a resonated (#11386) X pipe is perfect.

I'm thinking about throwing flanges on both the resonated and non resonated so I can free it up as much as possible at the track.

I did pick up a G37 swaybar ($30 for 38k miles ) and it mounted without issues. No more navigating the stock sway!

 

Sounds good man who makes that resonated x pipe? Magnaflow?

 

Yeah I believe magnaflow does and that does sound good..

 

You should def post a drive by vid. Sounds awesome.

 

Please tell me you got tuned with all that exhaust work... lol

 

Magnflow makes both the x-pipe and one that's more a muffler which includes the x-pipe. The resonated x-pipe might make your exhaust slightly quieter but won't have much to do with rasp! Watching the vid what are you running in place of your OE cats?

He has long tube headers, don't they eliminate stock cats??

 

Long tube headers....

 

Heading to Z1 next weekend.

With longtubes volume = rasp. Lowered the volume and got rid of all of my rasp.

The stock manifolds cause that cackling rasp that everyone hates. I loved these PPE's even with the non resonated X pipe.

The Longtubes also extend down and exit where the cats exit on the stock exhaust. Equal length primaries even longer than the SG motorsport headers.

Not expecting too much on the dyno being non rev up and on stock cams, but cams are already in the summer plans.

 

Sorry to bump this thread, but do you have high flow cats right behind the long tubes? What are the two cylinders connecting the LTs to the X pipe?
