What is the buzzing in my exhaust???
So, I get this 2011 Pace car--#230/500. Beautiful car....Exhaust sounds like a civic compared to other stock muscle cars. Anyway, researched this forum and decided on removing the mufflers. Yes, it does sound better. But what is the dang buzzing I am hearing? It is the L99 convertible. Does it have something to do with those spring looking things on each side? I am about to have them take the resonator out and replace it with a dual in dual out Maganflow. What do I do with these spring things?? Thanks for your help and opinions..

You're probably hearing the AFM kicking in. its the thing in L99's that make the car switch off 4 cylinders at cruising speeds. Get a "Range AFM delete" and forget all about it

You generally only grab a cel when you start playing with the manifolds and cats. You can hack everything off behind the cats and you'll be fine. |

Awesome. Can't wait to get some sound. Terrible choice by GM to not compete with other stock muffler sound.

My resonators went to junk last year and caused the same problems. The old exhaust is now on it's way to a scrap heap.
