I have a set of Corsa Indy's with GTR tips and they have been installed on the car since new. After 5k miles.....they seem to have mellowed and maybe I have grown tired....but....under WOT they are nasty (thrashing sound) and under idle they sound like a delivery truck. Corsa tells me to spend more $$$ and buy their X-pipe but why ?? Corsa sells the most expensive system made and the sound should be pleasing at all times. Anyone have same experience ?? Ideas?? :crazy: :crazy: :crazy: :crazy:

 

I had this *same* problem. I bought a Corsa Touring system for my '99 Coupe and hated the way it sounded. It sounded like a MAC truck and had some weird resonance "vibration sound" on deceleration that was terrifically annoying. I even sent it back and had them send a new system to me, thinking something was wrong with the first system, but the new one did it too. Besides that, I didn't see much if any gains on the dyno with the Corsa system over stock. I know the indy system is different than the Touring, but just letting you know my experience. I'll get B&B PRTs next time....

 

I put B&B PRT's on my 2001 Coupe a year and a half ago. Three months ago I bought a new Convertible that I put the exact same PRT"s on. On the 03, they sound like they have a rattle when they are warmed up. I can't find anything rattling, and the guys at Corvettes of Houston tell me the same thing - needs an X-pipe. I have read that on the forum, but don't understand why it did not do that on my '01 (the rest of the exhaust is identical on the 01 and 03).

I'm not sure what I'm going to do, because I really don't want to spend the money on an X pipe just to get rid of the rattle - if in fact it does fix it .

 

Why would a 800.00+ exhaust need another 300.00 (Xpipe) to make the system sound correct. I thought it had "patented noise cancelling technology"...or something like it. Please explain the reasoning ......

While Corsa and I have discussed the issue at length, maybe purchasing some Stingers and selling my Corsa's used would be the key.

 

Did you tell them that??? I would be curious to hear what their response would be. You touched on a point I have thought about for a while as I am looking into getting a new exhaust..."Why don't they package the "X"/"H" pipe with the exhaust if in fact it "needs" it??? :nonod: :flag :chevy

 

My friend has the Indy setup with the Corsa X-Pipe and he tells me that the X-pipe helps to smooth out the pulses, actually increasing H.P. ever so slightly and decreasing the burbling sound that you get like on a powerboat on deceleration. He loves it. BTW he also has it installed on a heads/cam car with LT headers! He told me the X-Pipe is a "must have" especially on a modded car in his opinion from listening to cars with and without it. Hope this helps just a little. :cheers:

 

my corsa's sounded ok and better with the x pipe. then i did H/C with headers and it was loud and not very pleasing sound. After I did the blower it really sucked so we dropped it off the dyno bolted on some GHL's that sounded great, and I got 18 more rwhp and similar torque. I never got a damn hp or # of torque from my corsa's.

 

GHL's are next on my list :yesnod: :iagree:

 

some of my contact with Corsa has been positive and they seem to want to help. I am still unsure of going any further into my own pocket to try this remedy at only cost to me is the smartest thing to do. Its list price is over half of what some good vendors sell the entire exhaust systems for....please chime in with your opinion as I need to commit/decline the xpipe today.

 

The x-pipe idea will work..but I would option for the breathless "off road" x-pipe..fits and sounds great!:D Stop by and you can listen to mine or check out this thread..http://forums.corvetteforum.com/zerothread?id=441631...:D

 

I love the sound of my Corsa's w/o x-pipe. I love the burbling/gurgling and wouldn't want to get rid of it. Exhaust sound is a very personal thing and what works for one person might be totally wrong for another.

 

After reading posts of others' exhaustive experiences with various exhausts, I decided to go with an X-pipe and Borla Stingers. I have had them on about a month now and love them!!

Bassani X-pipe almost new $200 shipped, bought off this forum
Stingers new $499 shipped ( from a non-forum vendor -- but got info off this forum )

Just keep checking this forum and you can get a good deal on almost anything you need.

:yesnod: :cheers:

 

What are GHL's ? :confused:

 

Jim Browning Jr. here from Corsa Performance. This has been discussed to many lengths, but I would like to clear up some of these questions regarding the X-pipe.

In 1997 under the early developement of our systems the original H-pipe had a complete 2.5" cross-section. The burbling tone was not prevelant then.

When we built the systems for the 98 Indy 500 Pace Cars, 2 out of the 3 had this funny sound... This is when we first found that the factory H-pipe in these cars were different. The earlier cars had a larger opening, allowing the exhaust gases to properly mix and equalize themselves. When they made a change, the opening got smaller, much smaller. By this it blocks a lot the sound, while creating a certain pressure which releases intermittently. Also, it became apparent that vehicles made during non specific build dates had either one or the other over the years..

Adding the X-pipe, allows the exhaust gases to mix and in doing so, gives the car a much cleaner sound at idle, under throttle and off throttle situations.

CORSA mufflers do not have any sound absorbant material which helps soak up some of this sound to a small extent. So it may appear to be more prevalent, however we have had many customers complain about this same sound with their stock exhaust systems too!

If you haven't already, you may want to visit our site to see the pictures of the factory H-pipe opening vs. the X-pipe.

I hope this helps.. and if Killrwheels has a problem with his mufflers, we would be glad to resolve any issues!

Thanks!

Thanks Jim for your response. I have your system on my 99. May get the X-pipe. More than happy with your Indy system!!!!!!!

 

I just put a set of indy's on my vette yesterday...so far I love them. I didn't get any of the burbling on decelleration but I wouldn't mind. :D

 

Get a generic x-pipe and the popping and MACK truck sound will go away. Of course, I won't do that to my MACK truck, I like it just the way it is.

 

Had the problem/sound at idle with the indys until I put the Corsa x-pipe in. It mellowed the wot sound a bit but idle sounded great.
Now with heads/cam, LT headers the exhaust sound throughout the power band is awesome. I constantly get compliments on the sound of my exhaust...

 

I love the sound during deceleration, it only happens with 6-speeds. I have the Indy's, x-pipe, TPIS headers and now a H/C package. It is a little louder since the H/C and has a nice old corvette sound during idle.

98 w/indys and now a 02 w/indys

Jim, it is clear that by this post the items I am experiencing "seem" to be related to the lack of an x-pipe. Unfortunately others within your business find it to be a potential bad muffler, although they freely suggest your product cannot fail, or can it, as some spot welds have been known to come loose in the muffler. Both your own people and some others on this forum have had to replace mufflers.

I already have your product, and cleary I have gotten the run around on repair or resolution. You admitted your product wasn't adaptable above, and expect your clients to spend additional money to repair your failure. (2 out of 3 = 66.667 percent w/ unnatural sounds) I also realize that some find this sound pleasing and unique, but it appears it was not originally designed to do such.

I am not trying to slam Corsa......as a matter some/most/all of my previous exhaust posts, I am pro Corsa :yesnod: :yesnod: :yesnod: :yesnod: . I wanted this before I bought the car, and am upset it did not live up to expectation. You say above you will work with me, well I look forward to it and hope you, Bob, and I can come to a reasonable resolution. I know the Corvette Forum loves a happy ending also :thumbs:
