That's about the best sounding clip I could get. Going down the on ramp with the windows up

I do not but I'll see if I can get my hands on one from a buddy

I had my corsa sport put on at a local exhaust shop and they left the resonator/3rd cat, would it be worth taking it back and having them remove it?

I originally took out the ONLY the muffler and replaced it with a super 44. when they started it up, i was not surprised at all, i barely heard an increase in loudness but did hear a much deeper sound. I was like **** i will drive a day to see how it is. the next day i went back and had them take out the resonator and clamp the valve open, never been more happy since

I had everything from the muffler back removed and had a Super 44 single in /dual out put in. Never heard of a better sounding truck and is loud as hell but being a quiet cab it doesn't drown out the music when in the cab.

Hey guys, has anyone removed just the resonator and left everything else alone including letting the valve continue to function?

Just wondering what this would sound like to start with before spending much $$.

Thanks!

On my 13 I had my carven TR installed and all I did was a muffler swap. Is it a noticeable difference without that resonator / third cat whatever its called?

I installed a Magnoflow 12909 - 22 inch and had to remove the resonator and the flapper. The problem I had was the flapper would make a raspy noise when closed & was super quiet with the Magnaflow and when opened it started rattling after a while. When I looked at the Flapper after removing, it is a much smaller diameter pipe than other sections of the exhaust. After all were removed (flapper and resonator) the Magnaflow sounds great and throttle response seemed to improve imho. Great sound with throttle, good rumble on start up, near same amount of sound as stock at cruising speeds. I wanted a sound like my 08 SD came with and I am a satisfied.

If you delete the DOD, aka AFM, it won't make a difference if you have the muffler flap or not.
