Custom exhaust build

I purchased my 05 with this "Frankenstein" Flowmaster/Dynatech exhaust system that sounded OK at WOT and more like a Ford down low. My build began with the 45' merge X-pipe normally used on our Porsche turbo systems. Stepped the diameter up to 3" , found some BMW X5 M resonators , Ebay s/s V-bands, Lucas Fab rolled 15" muffler cans and stamped end plates, Performance Tube 180' bends and perf tube , BMW Eisenmann muffler packing etc.

I then insulated the tunnel with special thermal sheet and Dynamat Xtreme. Also coating the Dynatech headers with thermal Jet/hott stuff. And the finished product:

That's just pretty cool. Get ready for the "You could have bought a Corsa setup for what you have already spent" crowd.

Be interesting to hear if you could do sound clips and also if there is any drone in the cabin. You are gonna have lots of fun playing with this!

My goal was to achieve a "flat crank" V8 sound with no high gear cruise drone. It's nice to "tune" the sound myself and learn more about noise dampening. I can have both mufflers out and apart on the bench in less then 20mins , thanks to V-band technology.
