Hi all, I came across this little item while browsing the web for some mods for my Roc, I was looking into going a dual Exhaust setup for my Roc so I can pinch out some more hp and sweet sound, but I came across this site and decided I would try these out http://www.dmhperformance.com/ see what Kind of sound and hp I would get.

If any one has purchased these items please post your reviews about them.
I will post some sound + vid shots of the Roc when I finish.





If this has been posted In wrong location, I apologize, can you please place It In proper location...TY

 

I recently bought one, but mine is QTP brand (Quick Time Performance) from Summit. The mounting holes are not oval and it does not include the pipe segment that is shown in that picture. As far as performance is superb!! No exhaust leaks when closed and installation is a breeze. The opening and closing time is about 6 seconds and it can be partially open or closed if desired.
