I had the complete Corsa L99 System installed on my 2012 , but with my current mods : Whipple Supercharger Headers HighFlow Cats and a Rotofab , it was too loud for my taste at cruising speeds, even low speed driving just a small change in throttle and it was pretty loud.

Couldn't see any reason to sell the Corsa System without at least trying the Mufflers only , I spent a few hours today and cut the Factory mufflers off right at the weld seam closest to the Muffler itself.
Then put the Corsa up and did my best to get them secured.
Will still need a Muffler shop to finish getting the tips straight and a small amount of weld for insurance , there is only about 1/4 to 3/8 inch pipe overlap,think it could work loose without some weld spots.

I am pretty happy with the results sound of tone change and volume .
Its a few DBs louder at the low rpm/throttle position and cruise speeds.
But when you open it up past the 3000rpm mark its pretty aggresive.

This is what i need to be able to enjoy road trips.

So ended up with some expensive mufflers , maybe even gave up a few HP in the mix , but at least the wife will ride with me again .
