o/r h pipes is better. a little advice instead of buyin new flowmasters if you kno anyone get flowmasters off someone gt their sellin it sounds better afta they been broke in.

Yea - right now I have a MAC O/R H midpipe. I haven't captured it on video yet. I wish you would have hit me up about the mufflers a month ago. I have them collecting dust in my closet. Hopefully they'll be on next week. Any pointers on chips?

i here alot of GT owners go with a JET chip. but personally i would go with hand held tuner. and if you have the time and money get it dynoed tuned. good luck with your Ricekiller

Thanks man.. I decided to go with an SCT hand held tuner. HP Gains were very noticable

[SAtownZ28]

no problem.. actually i have been looking into a tuner for my car. i might go with a hypertech or a FAST. either one i here give noticable increase in power.

Thanks - I noticed improvements on the highway - the sound is amazing when I touch the gas! The biggest improvement I got was from the gears
