so on the greddy site i was checking out an exhaust and theres the tic dual and single. the single is a turbo exhaust and im just wondering why they say its for turbo's cause you can be boosted with a dual exhaust. im just wondering whats the difference other than weight, and price. i know the single will get more gains but does a dual exit mess up the backpressure or something so it wont work with a boosted setup?

 

Don't pay attention to the names. The single is a 70mm straight thru and the dual is a 60mm iirc. So if ur boosted the single will be best.

 

im boosted and rockin the GReddy Ti-C dual.. though im SC'ed

i went from a custom 3" single to a GReddy Ti-C dual (70mm single to 60mm dual)

i noticed better response down low and mid rpms..
