Ok , I have a 2004 GTO. I wanna keep the exhaust exiting one side of car like it was from factory. I really like the sound of the SLP Loudmouth II. I would love to install Kooks headers as well, but I don't want it "too loud" because I have a state trooper who didn't like my '87 Mustang exhaust too well. Also , I helped a buddy install Kooks headers on his Pontiac G8. With their system it wasn't "too" loud until you stepped into it which was fine. I have full access to a rack so getting under it won't be an issue. I was curious as to how bad the install of LT's are on the GTO? It looks a lil tighter down there than the G8 did. I'm not fond of a banging noise at startup that might occur due to tight clearances either. I'm not planning on doing too much modding so exhaust , OTR Cold Air, and a tune is probably all I will do to it.
So gimme some advice fellow modders are the LT's a pain to install?
Is it going to piss my neighbors off , keep in mind Im not the butthole that sits and dry revs for fun?
Are the LT's worth the money for estimated 20 HP?
