NE HP Diff. between N1 n GT Spec

hey guys what the different between Apex GT spec exhaust n Apex N1 i know how they both look i just want to know the horsepower difference

u get about 8-10 more hp out of the gt spec and the gt spec is turbo back exhaust and it is stanliss steel 304 or sumtin like that. i have the gt spec and every 2 around me that has it, ENVEY'S it. i got great power and it also is not just cat back it gets rid of the resinator. thus givin thy mo powwa. in all ends, get the gt spec it is very deep and loud. u will not be dissapointed.

How sure r u on ur quote. Because my buddy has the N1 exhaust n it sounds pretty nice. but i never heard a GT spec on a two. Can ne1 else answer my response

im very sure on my quote and all the 2's around me want this exhuast. im also the only one with exhaust tho. i would get the gt spec if i were u.

you guys seem to know about exhuast, how does a hks super dragger compare to thoes ??

the hks is no big deal from what i have been told and the pipes are not as big as the gt spec
the gt spec has 3" replace the resinator then 3 1/2" from cat back and inlet to canister then 4 1/2" tip. very loud and much hp and better gas milage.
