I just put on my Helix DP and Catback on this Sunday. I'm very pleased with it. Haven't heard much on the Helix cat-back, but heard good of the DP. It's not too loud, well compared to my buddy's Nur Spec (That junk is LOUD!) Thanks to Calvin from Gruppe-S for meeting up with me in Emeryville on a Sunday to sell me the setup. Just waiting for the up-pipe to come in in late March. GraciASS.

 

Any chance you could post a sound clip of the new setup?

 

yea i second the sound clip, i would really like to hear that Turbo back, thanks

 

come by the BBQ this Saturday and you will hear all the catbacks and exhaust systems you want ...

 

Can I get the thread with the details...I have to work til 4:30 on Saturdays. Any chance I'll make it.
