Is anyone else disappointed in the Corsa exhaust? My exhaust makes just about every sound imaginable. Pops, burbles, marbles in a can, etc... These are not the kind of sounds I was looking for in an exhaust for a "luxury" car. I don't really mind the burble, but the backfires and pops between shifts are annoying as hell, and the marbles in the can sound is just plain brutal. My dealer has already replaced a resonator to try to help the situation, but they aren't familiar with the exhaust (mine is the only one they've installed), so they're out of ideas. Is there a place in the Philadelphia, PA/Delaware/Maryland area that installs these systems regularly and can help me out?

I have had the Corsa for almost a year and I am very happy with it. However, I have had a custom PCM tune that eliminated the burble and some of the popping (which occurs when the engine is cold and the PCM has the V running very rich). The stock exhaust does a good job of muffling the pops, but with the Corsa, before the tune, it can sound like a shotgun blast. My tune was done by DTE and they were a pleasure to deal with. Since then, StealthV has developed a tune that may be better at eliminating the popping. The added benefit of the tune is much better overall performance.

There have been several posts regarding the "marbles in a can" problem that you mentioned, but I am not sure how that was resolved. You should give the folks at Corsa a call to discuss the problem. It is a very nice group of people. They gave several of us a tour of their facility a few months ago and take customer service seriously.

Many people love the pops and burbles, but I agree with you, it is not what I want on a Cadillac. Aside from that, I think the sound is great.

I have the Corsa and am pleased with the "symphony" of sounds...I'd actually like it a little more raw.

Please keep in mind, you didn't really buy a "luxury car"...its an LS6, you know...with an exhaust there are going to be some funky sounds from a race-engine. From what I've heard, though, a StealthV tune should take care of your issues.

Be good,

I think the Corsa is great. I'm running a StealthV tune to get rid of the pop. Spent the weekend (a week ago) with the West Michigan Porsche club at the Grattan race track and you can't imagine the number of compliments I got from the Porsche crowd on my exhaust.

Here's the way to look at the Corsa exhaust...it is a performance exhaust that basically makes your Z06 motor sound like a Z06 and is not meant to be tame and quite. For a civilized exhaust system, the stock unit is perfect. For me, the burbles and pops are what a high performance exhaust on a powerfull motor is all about. Maybe a better move for what you are after would be the stock system with the center resonator removed. Good luck!

Same reasons I dumped mine. The CORSA is a straignt thru exhaust. Not for everyone. Get you PCM done by Stealth and you will be a lot happier with it.

Agree.

Corsa (& most of the other aftermarket exhaust systems) make the car sound like a high-performance car should sound like.

Too loud?

Come on now... :hmm:

I'm in complete agreement with Ace on this one. This isn't a "luxury" car. This is a high-performance car, period.

ronr, I spent the weekend in Mt. Tremblant(Canada) with the Audi Club. It was 20 questions about Corsa Sport on my '05 GTO. :)

Mine burbles too when I cut the throttle, rather than roll out of it like I normally do between shifts. This also keeps the passengers head off the headrest. :p

The StealthV tunes eliminate the pop/backfire. The marbles in a can racket has not been resolved as far as I know. In my case it seems to be the drive shaft striking the pipes just to the rear of the resonator; you may be able to adjust the pipes some to allow more clearance. Now it only happens to me when driving in very heavy rain and it goes away after a while; strange but true; maybe some sort of expansion/contraction problem. Corsa is supposed to be trying to duplicate the problem, so they can come up with a solution. So far, no word from them. Other than that I love the sound of the Corsa.

For sure, the Stealth tune eliminates all undesirable popping and farting (but only from the exhaust).

I ordered the "No marbles" Corsa Sport exhaust, so I haven't experienced that sound. Don't know what to tell you on that score... could your "marbles" be what some of us are calling "burbles?"

1. As per 10 or so other advisors -- get the StealthV tune.

2. The Corsa note mellows and deepens a bit with age. Mine sounded much better after 500 miles or so.

3. I believe that Corsa's RSC technology is responsible for heightening the pops and burbles. I have a similarly-designed Arrow pipe on my Ducati and it does the same thing. See: http://www.corsaperf.com/arsctech2.htm

4. Cadillac choose to re-sell Corsa, so dealers should generally be more familiar with this than other brands.

5. Notwithstanding 1-4, if you want "classic" deep tones, sell the Corsa and go B&B, etc.

Make mine the 11th comment about the Stealth tune, I had him tune out the pop/reduce the burble. Not that I really minded them much, but since he was tuning it anyway...

I love the sound of the Corsa, it's quiet on the highway, and just muscular enough to make sure the world knows I'm driving a Cadillac spelled with a "V".

About the Marbles, when does it happen? Start noting:

Does it happen when cold, hot, or both?
Under acceleration, deceleration, or both?
Dry pavement, wet, or both?

You get the idea. To trouble shoot further it helps to know what the conditions are under which it occurs. Then we might have more ideas for you.

I have had Corsa exhausts on my last 3 C5's, and my Escalade and I am very pleased. On the Corvette's you need an "X" pipe, that stops the pops and the motorboat sound. :)

Had the Corsa on since early spring. Love the sound and absolutley no "marbles in the can" sound issues. Once I get the Volant CAI on then I am going to the Stealth tune. Lately it seems that I get more positive comments from people about the exhaust note than any other aspect of the car.:bouncy:

The burble is result of the difference in fuel tuning from stock exhaust to aftermarket, a more open exhaust results in a lean condition that causes the pops. From others' experiences, StealthV's tune eliminates it...as a proper tune should. I like the pops, but it isn't optimal.

Teros1, are you using the Arrow chip that came with the exhaust? They are no better than the DP chips, and you can certainly find a better chip. Call Bruce at BCM in NewHampshire, he'll get you the proper FIM chip and you'll be much happier. I have the FIM with a 50mm Termi exhaust and absolutely love it. I switched to the single injector mod with the proper chip and it hauls...much less popping than before. Volare senz ali...(to fly without wings).
Ve good,

Not happy at all with my Corsa. Had one on my H2 Hummer and loved it. Not liking it at all with the Caddy. :rant2: Thinking of changing out my Corsa for the stock exhaust. Luckily, I kept it. I'll probably sell it, how much are they selling for, anyone know? If your interested email me directly to [email protected]. I'm leaving on vacation tomorrow for 2 weeks so I'll get back to you then.

You guys should get rid of those crappy corsa exhausts and get the real deal, B&B with x-pipe. Just put the latest version on this past weekend and only a deep beautiful rumble. B&B IS THE ONLY WAY TO GO.
