Flowmasters,H-Pipe,Stock manifolds and 22lb's

[INVNO1]

This setup as you can tell is killing my car!! What exhaust setup do i need for this amount of boost? Also i will be running dumps. (3.4 whipple) car made 622rwhp edit...

 

[Spade]

What blower are you running? That might help some of the gurus.

I'm running the 3.4 whipple @ 22lbs and the car made 622rwhp

LTs, and an X pipe?

But what mufflers? what longtubes? 1 7/8?

 

[theHumP]

1 7/8 would be great. I dont know what brand is the best but I have Mac 1 3/4s and they fit great and dont hang super low like other brands. I also run the Mac Produmps, they are as free flowing as it gets. Loud but tasteful IMO.
