Hi! W'sup, i'm a newbie here so bare with me ok?
Well, my friend just installed Arospeed Dual tips muffler on his 98 Corolla LE. I thought that it sounds nice on the outside and we can feel the power gain, but in the cabin of the car there's this loud buzzing sound that gets annoying at some point. Is there anyway we can eliminate that sound without making it loose power? I was thinking of maybe changing the piping to a smaller one or changing the cats but i thought that it would loose HP. Well, thank you for your time!

If the buzzing sounds like the muffler outside then the problem is most likely just the sound dampening in the car if its more of a rattle you might have a pipe resting on the chassis or another part of the car

It's the buzzing sound of the muffler that goes inside the cabin, so it is the damping.
Will dynamat do the job well, since it is pretty expensive? Thanks again.
