I plan on buying the Greddy Evo 2 exhaust, helix upipe and downpipe along with a Cobb accessport. I was first wondering about the fitment of the evo 2 with the helix combo. Also I was wondering should I go full catless or should I get the catted downpipe? I know some people have experienced back firing and that is what I am trying to avoid. Any help would be appreciated!

 

gruppe-s is running special on this right now, so they should fit fine.

 

fitment shouldnt be a problem . . . and if your worrying about backfire its almost impossible to not to backfire with a aftermarket exhaust. if you are catless w/ a bov and have a full exhaust you'll shoot fire out your tip so i deno if you still want this. hopefully you dont have a bov if you decide to go catless

 

No, I am still keeping the stock blow off valve.

 

don't get a greddy exhaust... save your money - go jic, invidia or aps.
