OK, I have decided to ditch the stock cats in an attempt for more HP. I will be installing the UTR Resonated Test Pipes (courtesy of MRC). I will also be throwing on an X pipe and Motordyne 5/6 iso thermal spacer. New tune will be coming from VRT/JWT. I am hoping to gain a solid 30+ more HP.

More to come.

 

Time to break the 500's!!!!! Well whp that is

 

How are you getting them to do the tune?

 

via phone and dyno

 

That should be an interesting tuning session lol

 

hoping for the best. Sharif is always 6 hours away LOL

 

when I ge my car back I will have to plan a ride down to check that beast out

 

when I took my cats off, my EGTs went down by like 100 degrees. FYI, expect some oil spray out of your exhaust now.

 

I wouldn't bother with an x-pipe on a turbo motor.. but that's me.

I'm still not convinced that the x or h-pipe theory works with forced induction. I'd just do the largest exhaust possible (or the largest I could fit/stand) for quickest and highest flow.

On my NA setup though, I am considering switching to an X setup.

 

I was thinking the exact same thing.
