If you have long tubes and high flow cats (Stainless Power in my case), how much louder do you think Corsa Sport is over stock mufflers?

Kind of debating that as I think Xtreme will be too much, especially with potential future changes to the motor.

I have the Corsa 3 inch ZL1 Sport catback on mine with LT's, no cats and it is about twice as loud as my friends cammed, whippled Camaro with LT's, HF cats, and stock catback, but I do have to say, I did like how his sounded with the stock mufflers, sounded pretty good! The startup bark was awesome. But yeah, mine is pretty loud, but NO drone at cruising, I like that.

I have the Xtreme, with long tubes and no cats. It is insanely loud - similar to no mufflers, which is crazy, since the mufflers are fairly large.

If I could do it again I would likely go with the Corsa Sport, but at $2000...I'm NOT doing it again. Corsa doesn't make an axle back or sell just the mufflers for our cars. Actually, I would prefer a valved setup over anything else, but that'd be even more expensive.

Not quite sure how much quieter the Sport is over the Xtreme.

From what I've heard of the Vettes with the extreme over the sport I have, I would guess it is about 20% louder than mine, and mine is pretty loud! The mufflers on the sport system are longer than the mufflers on the extreme system, but built the same inside. They are pretty much a straight through design from what I've seen of the inside of both. Here's some cool info.

If you look at the pics of the sport catback, and the extreme catback, you will see the difference in the muffler sizes.. So yeah, the extreme will be pretty loud.

I have the Corsa 3" Extreme system with LT headers and no cats.
It's Very loud. I liked it a lot and it had zero drone.

However, I did have to add a pair of in-line Borla 12" resonators because my local track has a 96db sound limit and I was regularly blowing 103+db.
Borla claimed they would knock 10db off and they did. I am hitting 90-93db.

I have been told that the Cats will have the same effect as the resonators I added, so you might be good with your current setup in terms of loudness.

Also if OP is interested, I got an email from Phastek this morning, their Corsa syatems are on sale with a 15% discount! Better than nothing if you're looking.

Got a ticket for my Corsa extremes a while back and at idle it read 96db. I have no cats or resonators with longtube headers.
