Radical08 Posted May 27, 2010 Report Share Posted May 27, 2010 Looking to see what was changed on the 2011 vs 2010. I'm thinking the only thing are the mufflers from what I see. 2010 has; cast iron manifolds x pipe what ever mufflers not sure if it's considered tuned or not Link to comment Share on other sites More sharing options...
JimC Posted May 27, 2010 Report Share Posted May 27, 2010 Don't know about the stock exhaust system, or what performance differences there might be. I can tell the 2011 aftermarket is a whole different ball game, a 2010 and earlier set up will not fit on a 2011. The only company I know of that has a 2011 system is American Racing. We, they, us had fun learning that one the hard way, you might want to contact them. jim Link to comment Share on other sites More sharing options...
GT500 rolls Posted May 27, 2010 Report Share Posted May 27, 2010 One big change is the move from 2.5" to 2.75". Link to comment Share on other sites More sharing options...
henrycp Posted May 27, 2010 Report Share Posted May 27, 2010 One big change is the move from 2.5" to 2.75". Do you know if that is from manifold all the way back? Wanting to install the "KR" axle backs (M-5320-SA). They gonna fit? Link to comment Share on other sites More sharing options...

I would put money on it. They wouldn't go to a bigger exhaust for just part of it as the 2.5" portion would restrict it in a way to negate the benefit of going with 2.75". That one area would be a choke point and negate the rest. I would expect there will be KR type options and others for the 2011s once more of them make it into the hands of owners.

Cdvision Posted March 15, 2011 Report Share Posted March 15, 2011 One big change is the move from 2.5" to 2.75". The 2011 also got an H-pipe instead of the X-pipe. Link to comment Share on other sites More sharing options...
The Batman Posted March 29, 2011 Report Share Posted March 29, 2011 I can confirm that the KR's, part #M-5320-SA, will not fit on a 2011 gt500. i found that out the hard way when i purchased them, got the car on the lift and noticed the different hanger positions and ball type joints on the stock pipes. also, the 2011's have a stock H-pipe. Hope this helps.... Link to comment Share on other sites More sharing options...
