I recently had a Corsa Sport system for the A6 paddle shift installed on my C6. I got the complete catback system (part no. 14167) including a new H-pipe with tunnel mufflers (resonators). I believe the purpose of the H-pipe with the resonators is to eliminate drone in the automatic equipped cars. I like the absence of drone, but I'm not sure I really like the sound of the exhaust under normal driving conditions. Now I'm wondering if I can replace the Corsa H-pipe with the stock H-pipe that was removed. In looking at the Corsa website, it looks like the Corsa part no. 14169 axle-back system uses the stock pipe. If that's the case, couldn't I use with the Corsa connector pipes and mufflers? Does anyone have this setup with an automatic equipped C6? If so, is there much drone and how does the system sound?

If im not mistaken, the two resonators are part of what comes with the touring system. The purpose is to make the system even quieter than sports. You should be able to just use your stock h-pipe. Best check with someone who has A6 tranny though.

 

You are mistaken. To convert to the touring system there are two additional resonators that install in front of the 'H' pipe. The resonators that are integral to the 'H' pipe are what makes the A6 version different from the standard version.

I'd encourage you to give the new exhaust some time. I've had mine on for about 500 miles and the sound has changed substantially. It is considerably louder than it was when I first installed it.

I can't imagine that there wouldn't be drone with the non-A6 'H' pipe...otherwise Corsa would have just stayed with the same system instead of developing a new one. This is just my opinion though...I have not heard a A6 car with the 'H' pipes swapped out.

 

I stand corrected.

 

No problem...I installed mine so know the system well.

There are actually two little short pipes that go in front of the 'H' pipe. Those come out and the additional resonators go in their place to convert to touring. I believe this is the same way the standard sport system converts to touring...it's just that the standard system has no resonators in the 'H' pipe.

 

I did a search to see if I could find any info. on the Corsa Sport system on an A6 without the Corsa H-pipe and resonators. I got tired of reading and didn't fnd an answer. I'm trying to determine if I can use my stock H-pipe and the Corsa over the axle pipes and mufflers. I think this is what the Corsa part no. 14169 consists of. I expect to get some drone, but if I find it intolerable, I can always reinstall the Corsa H-pipe resonators. Hopefully, someone with this setup will respond to my post.

YES, you can use them with the stock H-pipe. The drone will be there. Tolerance will vary.

 

Thanks, are you running this setup with the A6? If so, how does it sound and at what RPM range is the drone?

 

Actually I ran them with LG long tubes, and it sounded mean as hell. There was drone, and I could have lived with it, but the combo of the LG's and the A4 Corsa Sports, caused the passenger side pipe to contact the rear of the A6's tranny. To fix it, they had to weld it in a different position, which caused the tips to be misaligned. The A6 specific Sports will clear the tranny and will mate to the H-pipe. The drone should be less with the stock manifolds, so you should be okay.

 

Why dont you just call Corsa and ask them? I found their tech support quite helpful for my Corsa 14167 and they know their stuff. What dont you like about the Corsa under normal driving conditions? I like its sound/volume (dont love it) but just about everything else available has some drone...which is NOT acceptable to me. If you want louder, there is a price to pay for drone while freeway cruising.

 

I sent Corsa an e-mail tonight and plan on calling them tomorrow. I thought I'd post a message and see if anyone else is running Corsa Sports with the stock H-pipe on an A6. I'm curious to learn how much drone there would be. I'd also like to know how much that arrangement would change the sound. If I don't like the drone, I can always change it back. I just don't want to incur the time and expense if the stock H-pipe isn't going to work with the Corsa over the axle pipes.

I spoke to Jeff Rizzen at Corsa today. He's a nice guy and was very helpful. Ever since I had my Corsa Sports installed 2 weeks ago I've been troubled by a sound I hear coming from under the console area. In another post on this forum, I indicated that I had the 2 weep holes on the resonators welded shut. I subsequently ended up having the welds ground off to re-expose the holes. Afterwards, the sound returned. As a result, I posted this message as I'm now entertaining using my stock H-pipe as an alternative to the Corsa H-pipe with the resonators and associated connector pipes. According to Jeff, the stock H-pipe will work with the rest of the Corsa system. He indicated there may be a small amount of interior resonance, but he didn't think it would be overbearing. As an experiment, he suggested that I replace the Corsa H-pipe with my stock H-pipe. If I found the resulting sound level acceptable, he would then exchange the original A6 Corsa H-pipe for a Corsa XO pipe. The end result would represent an exchange of roughly the same value of the A6 H-pipe and resonators. He also said that he felt the Corsa XO pipe would be somewhat quiter than the stock H-pipe as well. He even offered to do the swap for me if I was willing to make the 2 hour drive from where I live to the Corsa facility in Berea, OH. I was so impressed with Jeff's customer service, I'm going to order a Corsa Sport system for my H2.

Hi...have spoken to Jeff Rizen too and he knows his stuff along with Paul Santiago. When I got my Corsa's off the Internet, one of the tips had a scratch in it and also took the long drive to Corsa in Berea. They promptly exhanged the muffler/tip and got a free Corsa hat. Stopped again back there to get my Corsa Sports tips re-aligned which was much better than I did
I also got a factory tour from Paul at the same time....very interesting. So too, am so impressed with them, am going in again next week to have Corsa's put on my Monte Carlo.

 

I'm in the service business so I always take note of good customer service from others. What really impressed me was when I told him that I had the drain holes welded shut on the resonators only to remove the welds to re-expose the holes. I figured that voided my warranty. His response was that I wasn't supposed to hear any sounds from under the car other than the exhaust note and that he would gladly exchange any part to ensure my satisfaction. This type of experience only reinforces the saying "you get what you pay for".

 

Mike, I have the Corsa Sports and have no issue with the sound. I will l ook for you on 6 mile.

 

Mike...would appreciate your keeping us posted with how the sound changes using the stock 'H' pipe and Corsa X-pipe if you end up going that route.

It will be very valuable information for those of us with or considering the sports for the A6.

-Thanks

 

LAX - I'll be l king for you. I won't be in the C6 until sometime next week. I'm getting a brick paver driveway and the car's in the garage. In the meanwhile, I'll be driving either a Pewter H2 or a Pearl White LS430

C-INRED - I'll be sure to keep everyone apprised of the results. It will probably be late next week before I can do the swap with the stock H-pipe.

I have a 2006 Z-51 with a A-6. I installed a corsa sport cat back system and there is a little drone @1700rpm but not bad.

 

Gregg, do you have the full system with the resonators in the H-pipe or, are you using your stock H-pipe? I plan to switch back to my stock H-pipe and if that's tolerable I will subsequently use the Corsa XO pipe. Before doing so I wanted to get an idea of how the system sounds if the resonators are not used on the A6.

Well, I swapped out the Corsa H-pipe for the stock H-pipe this evening. The first thing I noticed was that it was much easier to get the tips in perfect alignment. The minute I started it, I noticed a difference in the exhaust note. I drove the car around town and on the freeway. There's some resonance under certain acceleration conditions, but definately nothing I find objectionable. To be honest, it sounds exactly like I expected it to sound when the system was first installed. One thing is for sure, the sound I didn't like is gone. It's been replaced by much more robust sound that I don't find intrusive under normal driving condiitions. Corsa told me they would swap the Corsa H-pipe for one of their XO pipes if I was satisfied with the sound without the resonators. At this point I don't think I want to do that. Maybe they can cut me a deal on an exhaust system for my H2 instead.
