The stock truck is just too damn quiet for 520HP. I needed to shake things up a bit. I talked to Rob at Leistung and settled on his Secondary Pipes and and the Supersport Exhaust.

Rob made some tweaks to the design on both the secondaries and the rear X pipe. The secondaries now have some nice adjustable mounting arms on them and the X pipe is 3" and has a new ball type joint to give the rear muffler 360deg of adjustability. It all went together nicely but took about half a day since I was really making sure I got it all assembled straight and without leaks. The top nut on the stock secondaries is PIA to get to. But, with a shorty 13mm I was able to get it off. The adjustability of both pieces gave it a lot of flexibility in positioning and it all went in like stock.

Now the sound...finally it sounds like the bad-*** it should. Boost comes on much quicker off the line and now I find myself pulling to redline just to hear it roar. I have the intake on order and it will be in next week. Can't wait!

I will post some install pics and sounds later. Time for a brew now.

Congrats and enjoy!

Is Leistung still selling parts? I've tried relentlessly getting a hold of them for some items, to no avail.

Sounds like your new exhaust is a thumbs up in all aspects!! Looking forward to seeing some pics and hearing the rumble!

how did you get a hold of him? lol... how long did you have to wait for the parts?

I thought they had ceased trading

I MUST hear this, . I think I'm in your neck of the woods too, and I'm looking for something different on mine.

Sure, wanted to meet up with you anyways.

Leistung took some time off in July. They are back at it now. I just talked to Rob today. He has been traveling a lot lately.

What's the cost for the parts if you don't mind me asking?

Congrad on the exhaust. Looking forward to hear it.

Do you have a video showing it?

I agree - Leistung has great products...Had an exhaust put on my 2006 Cayenne S and it roars now. Even wife likes the new noise!
