so guys i am getting a 2.8 pulley, 60lb injectors, tensioner belt, and a tune thursday so how do you guys think i will like it?????"????

 

you'll love it and possibly scare the **** outa yourself the first time you get on it.

 

you serious man and question for anyone guys should i take the cat off and run three inch exhaust from the header back

 

no.... 3 inch dp.. maybe... there have been PROVEN losses of like 10 or more hp with a 3 inch compared to a 2.5

btw youll love it... haha!

 

stick with 2.5" exhaust.

 

ok what size exhaust is on there now?

 

stock has 2.25 from the axle back. down pipe and mid pipe are 2.5" and the manifold is roughly the diameter of a pencil

 

There is No reason to mess with the Cat, There is NO restriction or HP gain to be had.

We made 390 WHP with CAT and 2.5 Exhaust.

Ted.

 

missinformation. It's been proven that going catless provides gains. It's been proven that going 3" provides losses. 2.5" catless exhaust is going to give the biggest gains. SEARCH.
