Who makes the largest piping diameter dual set-up? I've been doing a lot of searching on this and so far I've found that the T1R dual is 63mm. Anybody bigger? I know that ultimate racing has something bigger in a dual, but not interested in there set up. Preferably JDM Getting ready to do a supercharger, but with higher than normal boost levels. Would like to keep the dual look, but if performance is going to suffer than it's just not worth it in the end.

 

UR is the only one that I know of that is larger than 63mm

I think the only other thing would be Blitz universal mufflers that have the 70mm piping coming off the back. Then you fit a custom Y to a straight pipe to the header.

 

63 is not that bad. Just make sure you get a test pipe.

There is a person on this forum that makes over 450hp, S/C'd with an Amuse Dual (63mm) with test pipe.

 

I thought the Amuse dual was 60mm piping? What happens coming off of the J's header at 65mm into 63 or 60? Like I said, the dual look on the Ings bumper looks great, but if single is how I need to go to not loose power then......



by the way...anything that doesn't bolt right to the header will have a test pipe.

 

Another option would be to contact Cody at LoveFab. He said that he was willing to build a custom 3" dual exhaust system, and he always has performance on his mind
