M37x Aftermarket Y-Pipe?

[JCesar]

I need your help guys trying to find an aftermarket Y-Pipe

I currently have Invidia HFC's and a full Stillen Exhaust but as luck would have it, Stillen doesn't give you a Y-Pipe because of R&D. I need to replace my Y-Pipe since I get a Rattle coming from it that comes and goes. the pipe is so restrictive compare to everything else I have that something happens in there and it rattlers. I was told that ARK has a system that does give you that part but looking at pic in their site, it wouldn't work for me due to the fact that they interdated it with the resonators so it wouldn't fit.

What are you guys runining instead of the factory?

I think the consensus was just to have an exhaust shop make a custom one rather then try to make an off the shelf part work.

I think that would be the best thing to do also

or if you read this you may consider not replacing it.

One thing that wasn't mentioned in that post was if the car was UpRev tuned after the Y-Pipe installation. Although not necessary you will never pull all the power from that mod without it. Given the inconsistent nature of these engines it doesn't surprise me that people have had different experiences with this mod.

Edit: I can only vouch for the inconsistency in the 5.6, not sure if it is an issue with the 3.7's. By inconsistent i mean that some of the 5.6's love to run rich and won't take well to leaning out and some will take it just fine and run better.
