New 3" X pipe exhaust
#121
I had a 2.75'' catless Fabspeed X-pipe and it had their 4 individual mufflers on it,,all I can say it was the sound was very annoying in the cab and I went back to my 100 cell Milltek and am a happy camper again..

John, It's all in the design of the system. As a manufacturer, you have to spend the time to test the sound of various components, not just make a pipe to fit or look cool, as that usually does not work out sound-wise...as an alternate viewpoint of a 3" X-Pipe that the owner did not find annoying, I just received this email minutes ago from a customer that just installed a SpeedTech 3.0 X-Pipe:
Hi John!
You've asked me to provide you some feedback.
Here it is : I love it!
Finally made it and put it back together following your guidelines.
The cold start up is killer,my favorite part. It quiets down as it warms up,which I like and it comes alive going up gears.
I think I've made the perfect choice getting your system. I've heard them all and for me, in order to spend for a new system, it had to have made a big difference from stock. I didn't want to spend almost 5K and get a little difference. I wanted GT3 sound and for a Turbo, it is pretty close. Love to hear those Turbo spool too!
They are all different (X-Pipes) and IMO, many of the X-Pipes on the market are not the best sounding. We took the time to insure our sound was something the typical 996TT owner would love and we get similar emails to this one all the time!

True,,
As you know though, cats and muffler design goes hand in hand with any system...As does the most important spec is the pipe diameter to make a complete package..

I think people confuse loudness with drone. Loudness of an exhaust can be controlled by a muffler. The number, type, and size of the mufflers can decrease the loudness (inside the cabin and outside of the car) of the exhaust. Adding large mufflers can also decrease the drone.
What I wanted was an exhaust that sounded aggressive, was pretty loud, but didn't have any drone (aka: the low frequency vibration that rattles things in the car... including your brain). Adding the helmholtz resonators eliminated the drone and then Chris was able to separately tune the loudness of the exhaust to exactly the sound that I wanted using the smallest sized mufflers that were necessary. Obviously the loudness/sound of the exhaust can be tweaked based on an owners preference.
If you just use a muffler to eliminate drone, you end up with a massive, heavy system, that muffles the sound and reduces flow (stock exhaust).
I'm still extremely happy with my setup. The wife and I took the car out to C&C in Richmond yesterday, which is about a 45 min, mostly highway, drive each way. Not a single complaint about drone despite keeping the rpms at 2400-2800 the entire time. My TBSS with stock exhaust draws more complaints than the Porsche. So trust me, she would let me know if there was drone

Still haven't gotten around to it This would have been the perfect weekend to get some video but the car is in the paint shop right now... I promise I'll get around to it soon!

Not sure why it would sound like a leak. Those tubes are capped, so all the sound exits at the tips....

Guys the extra pipes are capped at the end, it's not for more flow. It's a resonator, removes drone through a mathematical calculation of wave length canceling. Most of these type of pipes are quarter length resonators.
Often referred to as Helmholtz chambers but are technically not the same but used for the same purpose.

Apparently corsa has this theory incorporated in their mufflers and have for a while.
I think I'm going to do it in my x pipe I built. Won't be nearly as pretty.
