Corsa Exhaust Available Soon

[tommycap30]

I spoke to Corsa today and they are finishing up a prototype system and getting ready to start dyno testing.They are sending me info and I will be happy to pass it on to anyone who wants it.I'm planning to add a system to one of our GTO's as soon as it's availble and I have dyno results.Our Chevy store that sells a lot of Vette's installs them all the time and have had good results with them.They have a cat backk system available for 04 Grand Prix's that adds 10hp at the wheels and I will be adding one to special edition Comp G that I have coming

[Adam4356]

Nice. If you could pass that info to me i'd be interested. I've heard good things about corsa and really like there tips. :thumbs:

[tommycap30]

No problem.Theyre sending me the info and we plan to add one to one of our GTO's as soon as I see what the dyno results are

Obviously, your service manager is a little more liberal than most, regarding warranty rules. I was offered a deal for submitting my car for header development. Service manager said warranty would be voided. Period.

[DevilYellow]

I hate that, it should only void the exhaust warranty and nothing else. Corsa sells GM licensed products and dealers offer them.

Our Chevy Store sells a ton of Vette's and they put cat back systems on a lot of them.They haven't had any problems.I could see if it was a supercharger or nitrius system but a cat back system or headers wouldn't hurt anything.It's no different than putting a K and N airfilter on.For that matter I have several conversion trucks on my lot that all have aftermarket duals and no problem with the warranty.On the other hand,back in the eraly 90's when I was a service advisor in a Buick/GMC dealership,We were required to scan the ECM of every Typhoon and Syclone that came in for warranty service and check the Prom Code.If it wasn't factory we had to fill out a form and fax to GM that voided the warranty

You need to get a copy of the Magnuson/ Moss act from SEMA and drop it on the service manager's desk. To sum it up a dealer must prove that the aftermarket part/ accessory caused or contributed to the problem to void your warranty!

Bringing your car in for a warranty repair such as a bad alternator or something they would have to prove your headers caused or contributed to your alternator failure.

DY is right though some dealers are more forgiving or not such "a$$es" about aftermarket adds and some are not!

Thanks, Tommy. I'm not sure how the whole service thing works. I was under the impression that one was encouraged to have service at the dealer who sold it. I suspect that warranty work is not all that profitable, and thought that they might resent working on cars that were purchased elsewhere. I live on the east side, but purchased on the far west. I would love to go to a certain nearby dealer on I-90 in Euclid, very close, but they treated me like an idiot on the trade in. Actually, an old dear friend is the owner of Motorcars group. I would have loved to buy the goat from him, but his allocation was tiny. Next time I'm down Canton way, I'll pay you a visit. What are your off days?

to start, the Magnesson Moss Act is very specific. It states the factroy is responsible for proving the item you installed caused the warranty problem you brought it in for. Being a GM Service manager, I know the majority of them are are brain washed. however, part of the problem is items installed can interfere with the repairs they are trying to make, plus some GM reps can be ugly to work with and deny claims after they hve made repairs. We are one of the largest accessary dealers (GM and aftermarket) in California. They ae watchingg my warranty expense extremely closely with a lot of scrutiny. Service managers do not have a lot of free time. So most of them do not want the hassles. You need to find one that will work with you. Sometimes just sitting down, and having a "car" conversation and letting him test drive your vehicle, may be all it takes.

Also, GM is a distributor of Corsa exhaust systems. We have installed over 200 of them. just finished one on a GTP. They are great systems. GM warranties them for life. there is no welding/cutting involved. The systems are made exactly for the application and are all bolt on stuff. Again, Corsa stuff is awsome :)

DMS - what does a Corsa system normally go for installed by the dealer (roughly - I know you can't give an exact figure)? I live in NJ and am looking to make a few upgrades.

Also - do you know if GM dealers will be allowed to put on the LS6 heads and Z06 cams - to bring the GTO's up to Autocross levels? The car is an A4 - which may or may not be an issue.

Thanks

Do they do headers, or just catbacks?

Cat back systems only

[mistermike]

So far, the couple of folks posting dyno numbers on catbacks, have shown relatively mild gains over stock. Despite the flattened spots on the factory plumbing, could it be that the stock exhaust isn't as bad as some may believe? DY, on the other hand, really lit up some nice numbers with LTs. Perhaps the factory manifold/cat combo limits what a better catback might be able to accomplish downstream.

What are your off days?I'm off Fridays and Sundays except for the last week of the month.Stop down anytime.I'd love to see your GTO and meet you in person.Your warranty is good at any Pontiac dealer.My customer lives up your way and had a problem with his washers freezing right after he picked it up.I called Pete Baur and they got him in right away and were very pleasnt about it.I've always heard good things about them and theyve had a great reputation even back to the early nineties when I was working for a small Pontiac Store

Corsa has said its in the tuning, but even if you look at tha A/F ratio I and take into consideration that the PCM might be hindering the performance I doubt a solid 10HP will be gained from the catback with tuning ON A STOCK CAR. If I had a heads and cam the headers would help me out even more so and dropping the catback would also make a larger difference.
