Resonater?

I just got the cats cut off and was surprised at the increase in the db. It's very loud now! More then I thought.

Are there any resonaters I could buy to quiet this down a little? Even at 2200rpm on the highway it's pretty loud inside. And then when you crack it open at lower speeds....wow!

thanks

Re: Resonater?

Catalytic converters make great resonators. Put them back on like you're supposed to, and enjoy the cleaner air and lower sound.

yeah at some point I might put some big high flow cat back on. Trial and error is my motto!
