Installing RENNtech's new SL65 exhaust

All,
A quick update, since I've been quiet for a bit -- EuroElites is installing RENNtech's brand-spankin-new SL exhaust on my SL65. The car currently has RENNtech's ECU, TCU, airbox, and intercooler upgrades; we'll do a before-and-after dyno as well as weigh and photograph the new exhaust. I should have all the data by late this coming week.

Early word on the street is: +10 HP, a nasty exhaust snarl under WOT but no drone or excess noise in normal driving, and considerably lighter than stock. We shall see!

Whats the price on that bad boy? Also, did you get any gains from the airbox? I hope the sound is sweet!

The airbox picked up a TON of power - the car went straight from 11.4 to 11.2 at the dragstrip. If I recall, it made >40 RWHP on the dyno.

The retail price of the bad boy is $3450, of course mbworld members SL 65, SL 55 gets a good deal from EuroElites. (We love our mbworld clients)

I will find out soon, but honestly the TB is not available anytime soon.

Ben will most likely post the pictures, dyno charts and sound clips. So be patient guys!

Rumors are that the new Renntech stage 3 cars gain additional 70hp/70 lbs torque. So add that to stage 2.

Cool Hey Treynor :-)

Hey Treynor, long time no see big guy :-)
Can you give us some more info also on your new 997 turbo? What power are you running now and what are you plans for it in the future? What is your ultimate horsepower goal for it?

How much power (rough approximation) will your SL 65 have after the Renntech Stage 3?

Thanks

The 'turbo is currently making 560 HP (ECU only), and is on its way to 650-675 in the next few weeks as we put on exhaust, headers, and turbo upgrade. I'll stop there... for a while

Thanks
With the exhaust, I expect to be making 600-620 RWHP in the SL... enough to get out of its own way
