Exhaust

[HespelerC4]

Has anyone put louder mufflers on their c4? I don't care about the horsepower of a full cat back just would like a little more rumble. Can I just switch out the mufflers? If so what kind are best to give a little more noise without droning me out of thecar when cruising?

I had just borla mufflers, sounded great and no issues with drone.

I had Flowmasters on my C4 & the drone was un-bearable.
Magnaflows have a nice deep rumble, Corsa's sound great with no Drone.

I have magnaflows and I find them to be great. No annoying Rumble on drone. Just a nice souund on acceleration

Thanks everyone for the great feedback. It really helps

I added headers to my '85 C4 without changing mufflers. Performance was minimal but noticeable and the exhaust rumble increased significantly.

Thanks for the heads up on the flowmasters Mark!

Stainless steel, as opposed to the old mild steel that rusts, will give a different sound. Nothing major but definitely different. In the musclecars, Magnaflows were noted for drone. Well designed mufflers won't drone. I had stainless mufflers on our el Camino and the drone was a total annoyance. Do your research before spending a lot of money. Maybe I am just getting old but I like our 2005 just the way it is, quiet when it should be yet has a mean snarl when it gets down to business. Works for this old guy.
