Would you guies recomend a 2 1/2 inch exhaust or a 3 inch pipe one?

 

factory is 2 1/4, anything worth doing is worth doing right... misewell go 3 if you're gonna be paying for a new exhaust.

 

depends on how far you wanna take your power.. if you plan on upgrading turbo going with stage 2 or 3 probally best for the 3inch if plan on running pretty much stock stay with 2 1/2

 

A 2 1/2 inch is fine for anything up to and around 300 horsepower. Anything higher than that will run better on a 3 inch system. If you're going to go full bore on your mods, go three inches, otherwise, save some cash and go with the smaller size......

WhiteMnt's car ran low 11's on the Mopar 2.5" Cat Back

I would say go for the 2.5" unless you're planning on making more than ~350whp.

The 3" will take you up to the 550-600hp range.

I'm looking into a 3.5" exhaust for my car, and will likely go that route.
