Cats or bullets
Cats or bullets I don't want to lose to much power but what should I do here. I have pacesetter headers, offroad y pipe and a Corsa cat back. It is pretty raspy and i'm about to add a H/C setup. Should i just throw cats on it or what should I do. I just want whatever will keep the most HP and sound better.
I have yet to see any proof that people lose any noticeable power from the tiny cats that are used on these cars. They do a great job at removing rasp as well so I'd go that rout.
Magnaflow 59929. A very high flowing metallic substrate catalytic converter. Will last much longer than ceramic core units. Kills the rasp. Will make you lose a few horsepower but not noticable. They are fairly compact too.
Do your research. Many people swear by this unit.

Trust me, go with cats if you plan on keeping your corsa. A bullet will nto eliminate your rasp, take my word for it. It may tone it down, but anyone who tells you it totally eliminated the rasp is full of it. Corsa sounds absolutely sick with cats, but too raspy without them. Either run cats the right way, or go with a catback that sounds great with no cats
