GTM Test Pipes
Ive had mine on for almost a year now. I love the upper rpm power i feel with these. The car feels like a rocket past 4k rpms. I for one dont take my car into wot all that often, but im not afraid to get on my **** every once in a while haha. With this cool weather, i went to merge last night and the car propelled forward so fsat i had to hit the brakes to keep from running up the guys *** that i was trying to pass lol. I didnt really notice any loss of performance in the lower rpms. Its a tad bit raspy sometimes, but i attribute that to my current magnaflow exhaust. Ive heard other setups with the GTM rtps and it sounded smooth and not raspy. But really, the rasp doesnt really bother me all that much. Also ive never had a check engine light either.

I couldn't resist and pulled the trigger a few days ago...

Nice 
I'm about ready to but Black Friday set me back a little more than planned lol, so i'm gonna wait it out a little longer. Did you buy through GTM or another source? What exhaust are you currently running? Give tons of feedback when its installed bro. and a few video clips would be much appreciated.

test pipes shud always be non-resonated, n u may sacrifice the raspness for the performance
Not true. A rtp is still straight through and will outflow any hfc. Take a look at the inlet and outlet of any hfc and you will understand more clearly the differences
