Question about headers

I have a 06 GTO that I'm having headers installed this spring. Does anyone keep the stock mufflers when doing this or is it best to upgrade the rest of the exhaust? If I keep the stock mufflers will I notice a big change in sound? Thanks

If you are doing LTs, the stock mufflers will sound raspy and crappy. I ran that way for 3 months until I put on Kooks Afterburners.

Current: MGW-p, H-pipe, SS OTRCAI, Lovell rear springs, Eliminator shocks and Pioneer AVH-P3300BT, JBA LTs+catless mids, Drilled/Slotted rotors, Kooks Afterburners, catch can & Tune Next: ??? Wish list: Intake & TB, modest cam, UDP, gears

I have the stock manifold and Kooks Afterburners, which increase the exhaust note quite a bit alone. How much louder is yours now that you added the Afterburners?

With the LTs and no cats? Damn loud. But they sound damn good too.

I have OBX LT's, X-Pipe w/ muffler delete. When its cold there is a rasp right at 2k RPM's, but after its warmed up it subsides. Its loud for sure, but ya get use to it. Been complimented many times on the sound of her....
