That's a good question, but the CORSA has, in no way whatsoever, changed the low-midrange response of my car in the 17 months it has been installed. I was very careful to do (informal) back country top speed and acceleration tests, with Karen as timekeeper and CB operator, and no changes, before or after, were apparent. I can document a 0.5 mpg increase in highway (1660 miles, down and back) gas mileage to/from Florida, on 87 octane. .....and you oughtta hear the thing at 128 mph, steady, just under fuel cutoff. It sounds exactly like a car going past your seat on the tri-oval straight at Daytona.

HOWEVER, after last summer's lengthy discussions on aftermarket MAF's and throttlebodies, I shelled out just over $200 for an aftermarket MAF, which I discovered was a mechanically altered DELPHI OEM MAF. It made an instant adverse effect on low-end driveability (part and full-throttle stumble) and made absolutely no difference in the time from stop to 132 (GPS) mph, my limiter. It also cost the 0.5 mpg I gained above. The aftermarket MAF went back on the shelf. (The MAF was installed, a 4 minute job, after the CORSA, so the larger exhaust did more than just get the gas out faster initially, and the MAF countered that gain. Curious)

I reinstalled the aftermarket MAF 3 weeks ago, for no good reason other than I damn well felt like it, and had the same experience as before. The MAF is back on the shelf. I may put it up in the classifieds ^^^.

Wake, If you live in Montgomery Village (I grew up in Chevy Chase) contact me in here. We could hook up for a beer and oysters at Fisherman's and give you a look at my setup.

Glad to hear that, I might just have to get a Corsa system then. Of course it will have to wait until I find out what Uncle Sam is going to do to me this year... I sense great pain coming my way...

I do... I'm not much of a drinker, but as long as you don't mind me sitting next to you drinking tea or a soda, I'm game... I'd love to hear your system!!! I'm off for the next week so I might hit you up sometime soon...

i'd like to find out if the exhaust would sound any better without the center muffler installed on the system.

Did anyone remove the center muffler with a Corsa exhaust?

YEY! No more headaches!! Haha I love you but that old exhaust had to go. Plus you've been wanting Corsa since we started dating....

90devilleguy...........If you'll read the posts concerning this exhaust system, over the past 18 months, you'll find there's no advantage
to second-guessing the design engineers. The entire system is 100% straight through: no baffles, no packing, no screens, no cutesy
propellors, nothing but tuned straight pipe. Pull the front resonator and I'll bet the resulting 24/7 noise would run you out of the car.
If you cough up the bucks for a good exhaust, why try to get creative and butcher it ?? Let well enough alone, or, if you want "noise",
go to AutoZone and slap on a couple of ricer fart cans.

2003............Did your system come in 2 foam packed boxes ? How 'bout the color instructions.........You're gonna love it..........Sub

installed today
everything was there totally complete
what can i say
i kinda miss how loud my system was at WOT and the volume at idle but ill tell you what no way in hell am i going to miss the drone and all the noise inside when cruising!
i swear i feel a bit more power out of the corsa too but that could just be my mind.
the best part of the whole system, those tips, omfg those tips MAKE the system....
vids to follow of my system and the corsa system as well as pics

the corsas are the best systems on the market right now. ive installed tons of different cat back kits on tons of different cars and corsas simply sound better then them all, are higher quility, do not drone a single bit at any speed, sound unbelievable at WOT, and are some of the most well put together kits i have ever installed. i have it on my 01 sts and it was bought and put on 1 week after signing the papers and after my experiences with them on other cars and truck i knew i would be completely satisfied with them, as i still am 3 years later. no baffles, no packing, just a small sound cancelation chamber in the mufflers that cancels out all the bad resonances and makes for a great sound. they call it sound reflex technology, i call it my sts sounding like a zo6 vette with pipes going down the road and still beautifully drone free on the highway. i saw someone concern with low end torque, dont worry about it, your breathing 4.6 liters through a single mid pipe, thats all the back pressure youll need. your only going to gain horse and torque by freeing up some exhaust. if you got rid of the restriction in the form of a silencer in front of the air box under the fenderwell in the front youd get even more gain. and i can tell you with ported heads, cams, custom headers, and a custom cold air setup like i have on mine this exhaust simply roars, and the tips make the car look so much better and look unblievable when polished up real nice
