I have some X-cellerator exhaust systems that were used for testing and therefore can not be sold as new. They have anywhere from 25-200 miles on them and are in like new, perfect condition. Both 2.5 quiet and 3.0 loud are available. This is an opportunity to own a high end, high-flow system (either with cat bypass or 100 cell cats) for a fraction of the new price. For those that are not familiar with this system, it utilizes a V-flange component system for quick and easy swaps between the various configurations, which include cat w/ muffler, cat w/straight pipe, no cat (cat bypass pipes) w/ muffler, no cat (cat bypass pipes) w/ straight pipes. This allows you to reduce weight and back pressure for top performance at track events and quickly switch back to a normal street set-up when you are finished. And it's very quick and easy to do. Optional components can be added at any time.

Additionally, the cross-flow sound is well documented as being the best sound you can get on a 911TT. To give you an idea of the sound, I ran across a Ferrari F430 yesterday at a toll booth and we took off together. The Speedtech cross-flow sound was similar in nature and didn't give up anything to the Ferrari! I feel confident this is the last exhaust you will ever want for your 996TT.

I can do catless exhaust (race), 100 cell cat exhaust (street) or complete system with cats, cat bypass pipes, muffler bypass pipes, etc. - these special sale systems will be a great deal. Please PM me for details. Some pictures below...

Did I make the cut off, hopefully I will be sporting one of these soon

Josh,

Check your PM....you're in!

Please pm. me for price of 2.5"quiet and 3"loud. How load is 3" loud compare to Cargrahic loud? Thanks.

the link for the 3" isnt working.

Mark,

It works for me and I just tried it from a remote computer and it worked there, as well. It's a large file, maybe you need to give it a little more time to load? I think it's a good link...


aroonkl,

I sent you a PM, as requested.

Can you PM me for the 3" loud. Thanks, Mark

PM me for the 3" loud please.

yep, it works now, thanks! the exhaust sounds fantastic! have you done any testing in terms of flow with a crossover exhasut like this? Conventional thinking would lead me to believe that the exhaust gases running into each other would rob a ton of power. what are your findings? thanks John

Thanks and yes, I agree, the cross-flow design produces a wonderful sound! The principal of the cross-flow exhaust is that when a cylinder fires it is forced out the exhaust. This creates a vacume in it's trail, which helps pull the next cylinder exhaust out quickly. The cycle infinitely repeats and makes for very efficient flow. We have not done a back to back comparison to compare to other style exhausts, but there is every indication that the design works well. When I switched from a traditional 200 cell cat exhaust to the X-flow 100 cell cat exhaust, I noticed quicker turbo spool, improved throttle response and what felt to be an overall increase in power with a crisper feel all around. I believe a lot of has to do with the more effecient 100 cell cats, but when you combine these attributes with the exotic sound the cross-flow produces, it's like "ding, ding - we have a winner". Personally, I love the cross-flow performance and the sound is awesome! Having used our cross-flow for a while now, I strongly prefer it to a conventional design.

PM me please with the price of a 2.5 shipped to Florida
