markski Posted April 1, 2011 Report Share Posted April 1, 2011 (edited) Hey all, I installed the MRT off road H-pipe, VMP pulley and tune from Justin last weekend on my 2010 GT500. Just as others have experienced, the pulley and tune turn the car into the beast it was supposed to be. Here is a link to the before and after videos. The mufflers are still stock.

TheOtherRob Posted April 1, 2011 Report Share Posted April 1, 2011 Been thinking about doing this on mine, sounds like it might be a little on the raspy side? Sounds mean on decel... Quote Link to comment Share on other sites More sharing options...

The pipe if from MRT. There isn't much interior noise at idle or low rpm in a higher gear but you really hear it when you get on the pedal. I made some interior videos over the weekend that I have to edit and post. Quote Link to comment Share on other sites More sharing options...
markski Posted April 22, 2011 Author Report Share Posted April 22, 2011 I updated my video with some in car footage with windows up and down for those who are interested. Just an FYI for those who are thinking of purchasing from MRT, they say you need an o2 extension but the stock wire reached just fine. The part they sent also did not mate up to the factory harness, it had a different configuration. I didn't find that out until the car was on the lift with the new pipe installed. When I called them about this they said I could have just clipped off one of the prongs so it would connect, not a fix I would prefer. They also made me eat the return freight on the extension.
