i love the sound of my car (bassani cat back system), but would like it to sound a little bit more aggressive w/o losing that sweet exhaust note.....i bought some 1 7/8 kooks headers,lg hi-flow cats,fast 102lsxr intake (ported).....mow much is this going to change the exhaust note?
However, the huge difference is when you press down that gas pedal. When you do that, your car will not sound the same in any way. From tapping it to stomping it, it’s going to scream.

That will be good as long as there isnt too much drone. I want to get to about 450 whp and Im hoping the headers, x-pipe w/hfcs, axel back and tune will get me close to that on my A6. Then may do the ported/polish IM and throttle body. Will all that get me there? Dont think I want a cam unless there is one that will net decent gains and keep the car very DD as it is my DD.

I picked up 24rwhp/21rwtq on my LS2 (cammed) with a ported FAST92. Same tuner (ECS) and dyno for the cam, and a few months later the intake.
