Here are my mods.. (2000 SS M6)

Thunder Racing 224/224 114LSA Cam
SLP Cold Air Induction kit (FRAM Airhog Filter)
ASP Pulley
LS6 Intake
Magnaflow Exhaust
JBA Shorty Headers

After tune I got about 360whp.. the tuner says exhaust is my bottleneck. I'm in cali and this is my daily driver so Im trying to stay smog legal so LT's arent an option

Just wondering if there are any other mods that I could get to irk out a little more HP.

Assuming you still have the stock flat y-pipe, You could get a 2 1/2in catted aftermarket mandrel bent y-pipe from mac. It fits all shorties and manifolds & im sure it out flows the stock y-pipe. then just add some qtp electric cut-outs aft of the cats and run wide open until you have to cap them from inside the car w/ the touch of a button cuz of a smog check or cops lurking near. Also, a ported TB would be a good idea since its generally worth bout 6-8rwhp on a cammed car plus its a cheap mod. jus my 2 cents

True, but I think the Mac version is only made for the '98 and '99 manifolds/cats...Bassani and/or Random Tech might make one for the '00s and up.

Yeah.. I know.. LT's would be the best route.

I was just wondering if a new Y-Pipe or TB would be worthwhile mods at this point

LT1LS1, im dumb, i didnt see the 2000 SS M6 part. Im sure someone makes a 2 1/2in catted mandrel-bent y-pipe that'll fit CrazeD_SS's JBA shorties like u said. Get that LS6 intake and ported TB also CrazeD_SS & get it re-tuned. U'll get results.
