Exhaust sounding raspier
So the other day I installed an exhaust, a HKS hi power cat back exhaust. Anyways at first it sounded really nice and aggressive and now it sounds a little raspy. Any idea why ? It mostly does it in second gear around 3000 rpm

Leaks will affect the rasp, check for soot.
Are you burning oil? Oil can contaminate the muffler packings, ruining the muffler. I'm suspecting that's what happened in my situation.
Burrs and misaligned gaskets will also cause rasp/farts.

I've had a fair share of exhausts that have changed note slightly once they get a good coating of carbon on them (the black stuff you see in the tip) and as they "wear in." it's possible that it's just the nature of your particular exhaust system. Still, like the others said, check for leaks and tightness first. If you scrape, like I do, check for cracks around the hangers, I've had that happen before.
