im having a hard time deciding what size dp to order. i originally was going to buy the 3'' zzp dp. talked to a few friends and now they have me second guessing myself.

would 3'' hurt me? keep in mind i plan to go 2.5 catback.

 

If you don't have a good header the 3" dp isn't going to help you much.
Since you're just doing the 2.5" cat back, I don't see much point in the 3" dp though.

 

try to keep the DP & Catback the same size you might have the problem i have with keeping a good seal at the gasket...

 

no need for 3" with no f/i....stick with a 2.5 downpipe

 

alright thanks....does anyone kno where to pick up the zzp 2.5 dp?

 

um zzp?
