As with any louder exhaust combos, there are some, and it's not that bad to me. Of course, everyone has different ideas of what drone sounds like. Having said that, I saw a set of Borlas for sale at a very good price so I picked them up. I wanted a little bit more bass at the lower RPM range.
There's dynos floating around for sure. I'll let someone else confirm but you can expect probably 30-40hp from this combo?

Any update on the resonated test pipes? Pictures and/or a sound clip would be awesome.

Hoping to pick some of these up once I get back from the desert.

Got a call today from Matt today @ AUTOcouture, saying the second batch of pipes are in. (Already impressed with the service) Can't wait to install them and hear how they sound!

I'm very interested. I bought my 08 M3 used last year and it came with an Akra cat back and the rear resonators deleted. I'm debating getting the Akra x pipe or maybe just your test pipes. I guess I'm confused where the test pipe goes relative to the xpipe and and how the test pipes will be affected by my lack of rear resonators. Please advise me on what to expect. Thanks!

The primary purpose of test pipes is to replace the primary cats, which restrict air flow through the exhaust. By replacing the primary cats with test pipes, you increase air flow, which increases sound, and also allows the opportunity for increased horsepower provided you take advantage of a software update to match. However, it should be noted that the intent with test pipes, is to keep both the secondary cats and resonators from the stock x-pipe in place, to allow for some sound filtration. I'm a bit confused with what you mean by Akra cat back. Akra has two different systems. The X-Pipe (Which I suppose could be called cat-back, but isn't usually) and the Slip-On (Axle back). I'm assuming you meant to say you have the Axle back, because I would be very surprised if someone bought the Akra X-Pipe and removed the resonators. If you really did mean that you have the Akra X-Pipe without resonators, personally, I wouldn't install the test pipes on a resonator-less xpipe. I would double check to see exactly what x-pipe you have, and go from there. If you do have the Akra slip on (Axle back), then you could try the Test Pipes first, and if you didn't like the sound, get the Akra X-Pipe. It all depends on what setup you actually have.

Just to clarify, can the test pipes be removed and the primary cats reinstalled for smog testing? A pain but it just goes with living in CA. |

I assume this is a butt connection? How well does it seal if not welded (although I would most likely weld)? Is there documentation on where to cut the stock pipes so I can prepare?
And finally, price to 30066. Thanks. |

If anyone out there would like to get just the pipe, let me know, we can split the promotion and both end up happy as I only need the software.
We can both get the promotional price, $379 for the pipe, and $900 for the software. PM pls |
