Corsa sport with resonator

[ace ventura]

I'm having my stock muffler replaced with my corsa sport muffler only. If I leave everything else in place will it lower the sound output? Should I delete the resonator for sure?

Where did you find the muffler alone?

I put the Borla Touring Cat back on mine is it's much louder during acceleration but tones down a lot cruising. Corsa is similar to Borla with the touring and sport mufflers so if you put on the sport it will be a lot louder. Don't know about the resonator.

It will sound like crap with the flapper and resonator. I did the same thing on my first 2014 with a 14inch Maggie. The only way to get that good sound is remove the flapper and resonator and then you have to out run that invisible BlackHawk helicopter. Now Im on my third 2014 and after trying ever combo there is I have finally settled on a Flowmaster 50 and BBP tune that disables V4. Just cut that junk off, put on muffler of choice, and drive in M5 till you can get a good tune. Unless you just have a thing for helicopters?

I really like my Flowmaster Super 40 as well, no resonator, no flapper. I use the Range AFM Disabler to keep the helicoptor away from me.

I found the corsa muffler for sale by itself long ago from a member selling it on here.

So getting rid of the flapper and leaving the resonator will still make it sound like crap?

I have the full corsa catback. No flapper or resonator. You can definitley tell when it goes to V4 mode, but its not bad. I've heard worse.

 

If you want have them both installed with the corsa, and if you don't like how quiet it is...have them removed.

So i had my corsa sport muffler installed and its just as quiet as factory. I'm so frustrated. This was the muffler I had on my 2005 silvy and it sounded great. I had the flapper valve removed but kept the resonator. The install shop came and got me to say it's really quiet. I said maybe its the resonator so they cut it after the muffler and it was still quiet???? Did the design of the corsa muffler for the 14's change that much???

Sure it's not the Corsa touring?

yeah as i've had it on my previous truck and it had an aggressive sound.

The resonator will drown out a lot of sound. Take it off.

 

Edit:

 

Nvm. Saw you had them take off the Resonator too. What year was your old truck?

 

I know the Corsa I put on my trucks was basically a straight through design. I could see straight through it. Maybe the earlier model ones weren't.

 

Or it's possibly a Corsa Touring.

I replaced the corsa with a 18" magnaflow today and it's perfect. My corsa is a straight through design and it's a sport too but it must be for the gmt800 series only.

My old truck was a 2005 Silverado 5.3

What's the size on the corsa, and is it FS?

It will be for sale soon. I think all corsa' are the same size. They are big!! Couple of small dents in it but no biggie at all.
