Hey guys getting ready to switch from my duals to a big single side exit. I have an intake and exhaust now though my 220/220 cam is on the way. I'm leaning towards 4" but i'm not sure if it might be a bit big. Should I go with 3" or 4" for a single exit on the side infront of the rear tires?

 

Id say youd be okay with a 3"....but 4" looks cool....

 

id do 3"

 

I like the look of 4", i'm mostly worried of losing power with a 4". I'm doing it for the look, and becasue I'm losing power with my 1 into 2 system now.

 

Oh and there is boost in my future, probably SC maby turbo I haven't decided yet.

 

4 inch will be too big. Run a single 3 inch and run a 4 inch tip if you want that look.

 

 

Ok thats what I thought, I will upgrade to 4" later in life (want to eventually run 12-15psi boost)

 

Run 2 5" tips slanted out in front of the back tire. scsb had it here and looked pretty good nice and deep.

 

id say 4" infront of the rear tire but thats only bc thats what i have
