Best HP Exhaust upgrade?

hey guys, i was looking to get a new exhaust system for my 8 that would be the best performance-wise, or at least pretty good. I really don't care and don't really want a super loud lets wake everyone up sound. I saw a video with the "B&B" exhaust which didn't sound too bad. Anyways, i've heard Greddy SP2 exhaust is good, but any thoughts on good HP gain and still getting a nice growl sound out that doesn't get me in trouble?

Racing Beat Midpipe with Racing Beat Exhaust....If your going track/circuit.....Racing Beat MidPipe with HKS Legamax Exhaust is lighter. Like 20lbs lighter. Youll get anywhere from 10-15 HP (with intake) and video sounds are nothing compared to real life...TRUST...

don't expect 10-15 HP, even w/ an intake....10 at the MAX, and for the record, I have the exoticspeed exhaust, and I love it. Full 3" all the way back, and it comes w/ a midpipe

10-15HP

ALSO........Racing beat midpipe replaces stock midpip....a lot of exhaust systems require you to buy their midpipe with their exhaust.....so...FYI

how come everyone ignores single exit exhausts when these threads come up?

much lighter and they don't have a split.

HKS Hi-Power.

biggest restriction in the exhaust is the cat.

if you want best bang for the buck and most gain, get a catless midpipe for $100-200 and you're set.

best exhaust for the buck is the turboxs - it's 3" ID for full exhaust AND midpipe for $400 from an orlando based rx8 vendor. no other exhaust comes close. You will just want to drop another $100 for new tips.
