Happy with my magnaflow and cutout.

GMMG is cool though. Good luck with it.

Default dyno results
o.k so i dynoed the car again with the exhaust. first let me say i am extremely happy with the sound ,for me it has the right tone not to overbearing. On the hiway a very nice low tone, but when you give it some throttle it lets everyone know your accelerating. now my car is completely stock no mods at all except for the exhaust, the dyno results showed i netted 2hp more.Thank ful it wasnt a loss in power ,but i was kinda hoping for more. I did have the cme system already so i guess they are about the same, just a better sound. Over all im still happy. what do guys think ? do you think im in the ballpark for a stock engine with 15,000 miles? oh yeah this was on a dynojet dyno both times.
