Just wanted to get a feedback about exhuast systems for the ss/sc. I am looking a doing a couple of mods, such as the modified K&N, exhaust, possible header, and computer work.....any ideas from anyone would be extremely helpful.

 

Just go through the posts already in these forums dude. Everyone is blue in the face from trying to answer these same questions every day.

 

No one really makes a mass-produced kit just yet. There's supposedly stuff coming soon from Magnaflow & other big companies, as well as some smaller performance shops.

For now, though, you're limited to either having one custom fabbed like in this thread...

or just waiting around for a few months until some kits are available.

 

Just installed the 2.5 magna flow exhaust today sounds real nice. also installed the 2.85 pulley for the s/c. The intake from modern performance is next for me, they state no cel guarenteed.
