Exhaust help wanted : Vendors welcome - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I have a 2011 SS convertible. Has a Vortech Si trim. LT headers, cat delete, and stock exhaust from there back. I like that it has very little droan but it is too raspy/throaty sounding at idle and part throttle. I want a nice low rumble instead of rasp. It is SUPER loud at WOT but I'm ok with that part. It is an L99. I want to keep the stock resonator, so I've been looking at axle backs. Seems that most do not fit convertibles.

So, who makes an axle back for a 2011 Convertible without ground effects that will give a car with LT headers, no cats and stock L99 resonator a nice low rumble at idle and part throttle? All advice welcome, vendors are welcome to post or pm a price.

Thank you!

Save up the money to do it right.. Zl1 Corsa cat back. No drone inside. Amazing at WOT. Hit up Steve at RDP for the best pricing on the exhaust system.

Anyone correct me if I am wrong, I think there is a tunnel brace spacer available that would give you the space needed to run pretty much any SS exhaust.

I fit my 3inch piping thru my stock Tunnel brace without any need for a spacer.. Its all about how well you keep the piping pushed up during install i feel. there is also this but you don't need it really.

He has a convertible. The exhaust is slightly different from the coupe. I'm not sure exactly what the difference is, but I know most c/b systems are offered differently from coupe/conv. Corsa isn't a deep sound either. It has a very raw and unrefined sound. Loud as f*ck all @ wot with no drone. If you want deep, then look no further than the Flowmaster Outlaw axle-back. I'd for sure get a tune or something that disables the MDS mode as it will sound like horses ass in 4 cylinder mode.

Im running 14 psi ...... So already tuned. No 4 cyl mode for me.

I'm afraid the Flowmaster Outlaw will be too loud/raspy with running LT headers and no cats. Not seeing any of the other Flowmaster axle backs saying they will fit my car.

I see Borla S Type and Magnaflow Street both have an axle back for the convertible. I wonder which would give me a nice rumble? By looking at them, the S type is a small muffler, might not be a chambered design. I think I need a chambered design to give me the sound I want.
