okay, Im a noobie here and I know this has been asked a bunch of times, but I dont get a lot of chances to get online so Im just going to ask this and hope for responds. So I will be getting the vortech supercharger and I need to know what exhaust will give me the most power. I was reading and thinking of the J's header and custom 3 inch single exhaust. If I do that what test pipe will work and I do know that when it goes to 3 inches, it needs to be a gradual increase. So let me know if this setup will be the best. Thanks

 

That sounds good, but if you change your exhaust, be sure to check you AF ratio after. Mine was running lean with the aftermarket header/ TP/ exhaust.

 

T1R 70 mm

 

if you get a custom 3" single made why use a test pipe? Just have it built right off your header.

 

No man, the cool thing to do is to just run it out the header. No real FI guys use mufflers...those eat up power.

 

Hell Yea!!!

 

If I run the custom 3 inch from the header back, what will do with the sensor that goes in the cat?

 

you just have a bung welded in very easy.
