I have JBA longtubes with shorty off road H pipe on my 2010 GT. Originally i had flowmasters on them and it sounded great, but i figured why not see what the stock mufflers sound like. To be honest, they are a little less raspy and i think it sounds better with the stock ones on.
Now will this hurt my performance? I understand it may restrict my exhaust alittle by a few hp but it wont slow me down will it? Car feels the same to me.
Just wanting some input
