Edelbrock vs Magnaflow
 

I have an 02 SSEI. I'm looking at swapping out my mufflers later this fall or next spring. Does anyone know what the power increase would be for both of these types of mufflers? Which one is louder? I want a little more rumble but not too much. Mainly, I'll be looking for a little more pep to go along with my k&n filter. Any current owners of these products with feedback?

performance wise magnaflow is slightly better
sound well thats personal preference!

BonneMeMN has a good collection of exhaust sounds. Sounds
Your gains will depend on everything else like high flow cat, headers or ported manifold etc.
Say 5hp for the mufflers alone?
