Let me know if your interested.If you have this at end of week I may be giving you a shout. I absolutely LOVE the sound of the SW retro.
My guess is that it probably would not change much power wise. Not sure of the weight of the borlas but from switching to this exhaust from the factory exhaust it saved about 40lbs. Also when I was stock I ran 12.83 at the track. The next tiem I went after changing exhaust and to a little lighter wheel I went 12.67 with a little worse density altitude that day.interested, in houston. i currently am running borla atak axle back, and have read conflicting reports on axle vs. cat power gains. any insight on this before i pull the trigger? if it helps im also running kooks 1 7/8 lt and catted x. lemme know.
