I am wanting to put an exhaust on my 05 ralli art, question is if our stock exhaust is 2.5 already wouldnt it be cheaper to by a high flow muffler and high flow cat or what is the benefit from getting a full cat back? thanks for all the input.

 

Uh oh here it comes.....

love the pic

 

There isn't a benefit to a full catback unless you're going turbo or all the way with NA mods.

Please refer to the newb thread at the top of the Ralliart General forum for more info.
