X-Pipe question

X-Pipe question
I have a 2006 A6 with a GHL axle back exhaust. No headers and do not plan on adding any. However I am thinking about adding an x-pipe and wonderd what was my best option. Also what effect, if any, will this have on "drone"?

You already have an H-pipe
Which is to equalize left/right bank exhaust resonance in addition to "theoretically" balancing the exhaust & thus improving flow/scavenging effect, but the stock H-pipe I understand is not the full 2.5 diameter inside limiting it's capability of doing either very well, but does a better job on balancing resonance. A "real" X-pipe should improve both & go from theorectical flow improvement to actual, but no noticeable perf. improvement (on a stock LS2). At some point they started coming on stock C6s, so if someone who's gone full exh. route & has one laying around to give or sell would be your best option (bolt on & cheap), plenty of aftermarket X-pipes available to fit, more labor intensive than anything else due to cutting & welding. Call George at Kooks & see if he has any advise on both what & will it accomplish goal, he will undoubtedly know both. I use one in combo w/ complete exh. system, & believe they're worth doing, but I'm not so sure you're going to accomplish a terribly significant improvement w/ drone. Keep us posted, I'm sure folks would like feedback on the results, I'm curious myself. Good luck.

keyplyr and Mike V have provided a lot of good information on x-pipes and their advantages. Basically the main purpose of a crossover is to better balance the exhaust pulses between the two cylinder banks. The H-pipe does help with this however it is not real efficient. A properly manufactured X-pipe will help clean up the exhaust note and provide a little more performance. You can read more about out X-pipes at www.bbexhaust.com or give us a call at 888-228-7435.

PHUN4US, I believe adding an X-pipe to any typical V8 whether through headers or manifolds is a step in the right direction but real power gains come from headers. I'm not sure you'll see the real advantages an X-pipe provides while running through stock cats. X-pipes thrive on signal which gets interupted as the exhaust pulse crashes into the cats. This is why we place our X-pipe ahead of the cats on our header systems.
Just curious, why wouldn't you consider a quality header system? It's easy to install and can be brought back to stock if necessary just as easily. If I can address any concerns let me know. Thanks
