#8868, "3" Downpipe received and installed! HOLY SHIT!!"
Damn guys, you weren't kidding. I ordered a full 3" downpipe off of Ebay, labeled Megan Racing, 3" inlet, 3" Flex, 3" Outlet, no cat. I had some fitment problems connecting to my N1 Catback, but I went to a welder, got an adapter plate made and it is all better now.
The performance gains are amazing. If anybody has not done a downpipe, DO IT!! I'm speechless. And the tone of the exhaust is amazing as well. Not much louder at cruising speeds, but quite a bit louder and deeper at WOT. LOVE IT!
I have a video and sound clips of my car with an enormous exhaust leak, basically open exhaust. I had to drive it that way for a day, and I'll try to get some new clips of the way it sounds now.
