I was thinking

I have a 21 sgs. I was thinking about having the se highflow exhaust installed . I was thinking that would give better sound , performance and keep my warranty intact. I would upgrade the air cleaner with se ventilator extreme along with se tuner and auto tuner if they have available. Then once warranty runs out do the complete stage 2 with good quality aftermarket parts. My real question is are the se head pipes serviceable with just a better muffler upgrade.

I had great engine performance with the SE Highflow Exhaust. It sounds great (not too loud, and it has a nice deep rumble), and you will not need to change it after warranty runs out.

Thanks for the input. I perfer it not too loud . I do like the looks of the system , was wondering about changing out mufflers when warranty runs out so I could do away with cats. They said there were relocated into mufflers.

No need. The sound and performance is great and there is no heat problem with the cats back in the mufflers.
