SteelTownStang Posted February 17, 2012 Report Share Posted February 17, 2012 Just installed the Borla S-type on my 2012 GT500. While it sounds good, I would like more volume. Are there any 2 3/4" H w/high-flow cats available that can connect directly to the OEM mid-pipe? Also, would the high-flow cats make any noticeable difference in sound? Lastly, I'm planning to reinstall my 2.59 pulley w/tune. Any special tuning required w/the high-flow cats. Thanks! Link to comment Share on other sites More sharing options...

05mustangman Posted February 18, 2012 Report Share Posted February 18, 2012 Hmmmm... Interesting! Says its for 2011 only but looks like it would connect right to their longtube setup. Wonder why for 2011 only though. Link to comment Share on other sites More sharing options...
05mustangman Posted February 18, 2012 Report Share Posted February 18, 2012 You know i just found this as well. This is for 07-10 GT500's. Very cool, looks like these are interchangeable with the kooks x pipes. The system i got was the 1 7/8" headers and x pipe. I believe with the oem 2.5" connection. http://www.ebay.com/...5#ht_1495wt_905 And so far everything I've seen like what you want to do is using an h pipe with their cat back systems. Basically 3" systems. Link to comment Share on other sites More sharing options...

05mustangman Posted February 18, 2012 Report Share Posted February 18, 2012 I absolutely LOVE my longtubes! Believe it or not installing the headers and a tune picked up about 30hp and 35 tq. MBRP doesnt make one for the stock fitments only for their systems. But I dont think i want to go with an Off road pipe just because of emission issues. So far the high flow cats on my kooks x pipe have been working great. But would really love to have an h pipe just for the deeper throatier sound.
