GT500_012308 Posted August 8, 2016 Report Share Posted August 8, 2016 I have an 11 GT500 and I am looking to install an exhaust. I want it to be EXTREMELY loud I was thinking of going with lethal performance off road X pipe with either a lethal performance over the axle pipe with either SLP loudmouths or PYPES bombs or the lethal x pipe with a pypes cat back also I will be deleting the resonators Thanks in advance Quote Link to comment Share on other sites More sharing options...
sheppd01 Posted August 8, 2016 Report Share Posted August 8, 2016 If you want loud put headers on it. I don't start my car before noon for fear I will piss off the neighbors 3 acres away. Quote Link to comment Share on other sites More sharing options...
GT500_012308 Posted August 9, 2016 Author Report Share Posted August 9, 2016 so will catted or high flow catted headers be the same? Quote Link to comment Share on other sites More sharing options...
mavisky Posted August 9, 2016 Report Share Posted August 9, 2016 Borla Attaks seem to be a popular choice for people wanting maximum volume with a good name attached to them. Quote Link to comment Share on other sites More sharing options...
sheppd01 Posted August 9, 2016 Report Share Posted August 9, 2016 (edited) so will catted or high flow catted headers be the same?Mine are high flow catted only because I have a yearly visual inspections in my state. From what I understand uncatted makes a difference at above 800-900 hp. Not sure about any difference in the sound.

sheppd01 Posted August 9, 2016 Report Share Posted August 9, 2016 Yeah you have to lift the engine to put them on. I bought my headers from Shelby. http://www.shelbystore.com/product-p/Z52-S7M-9430-C178C.htm The one and only reason I bought from them was for the GT500 engraving. Not surprisingly the headers I received didn't have that engraving. I guess it was my fault for once again trusting Shelby to deliver on what they advertise.

GT500_012308 Posted August 10, 2016 Author Report Share Posted August 10, 2016 so all require engine to be lifted? Quote Link to comment Share on other sites More sharing options...
sheppd01 Posted August 10, 2016 Report Share Posted August 10, 2016 I believe so. It may be possible to do it without lifting the engine but it is so much easier to just lift it. Quote Link to comment Share on other sites More sharing options...
