SpeedTech 991 exhaust system
We are pleased and excited to announce our recently completed SpeedTech Porsche 991 X-cellerator exhaust design - 100% T-304 stainless steel, manufatured in the USA. The total system weight with the two dual mufflers, tips and hardware is only 28 lbs. A full muffler bypass X-Pipe is also available for a louder "race" sound and additional weight savings.
Our center muffler delete X-Pipe, designed to be used with the OEM side mufflers is currently under development and will be completed later this week.
As with all systems in our X-cellerator line of exhausts, our new 991 model relies on our proprietary "X" design at the core for it's exotic sound and the system is modular with other 991 components, such as the muffler bypass pipes. This allows the user to swap components, thereby altering the sound level as desired for special events, track days, rallies, etc.
Here's a couple of pictures -

Hi Justin,
The complete system pictured above can not be used with the OEM tips - it is a full 2.5" diameter exhaust (including the tips), which is a slightly larger diameter than the OEM mufflers/tips, so the tips are not interchangable.
A "Center Muffler Delete X-Pipe" is currently being developed to take the place of the OEM center muffler, which can and will be used in conjunction with the OEM side mufflers & OEM tips.
We are offering a special introductory price on a limited number of systems, then we will have an ongoing Rennlist Member Discount program, as with all of our exhausts. I will PM you the details of the introductory pricing.
Best Regards,
John

Weight savings = 25 lbs.
This system made an additional 15HP same day/same dyno on a very conservative Mustang dyno. I don't have a copy of the dyno sheet yet, it was just dynoed a few hours ago by an independant third party. The word from the shop was the system made very good power and sounded fantastic...they were excited and very happy with it.
