Im getting my plenum gasket replaced this weekend. will there be a noticeable power difference wen i get it replaced?

 

Not unless it was leaking before you changed it.Then it will be just the regular power it should've had unless you got the deathflash.You are using a aluminum plate and all that stuff,right.

 

yes if you cat isnt cloded up

 

well im pretty sure it was leaking when i bought it since back in about august i just didnt know about it till recently. because since i had the truck it didnt realy have that much low end power and would bog down goin up hills and stuff. and wat do i do to hollow out my cat because i dont hav the money to buy a high flow cat haha
