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.

Very cool, thanks for the advice to get it!

That's why we're here. :)

Is there any point in putting a 3" downpipe on a T25?

I have a 3" cat and catback, but I couldn't really justify getting a 3" DP for it.

thx

I don't know about a t25, that is why the pro's are here, but my Big16G spools to full boost, 18-20psi about 500 RPM's faster!!!! Approx 3000-3200 now.

Ahhh, I can't get over the sexy ass sound of my exhaust now!

i love hearing that whistle in the exhuast :) people know somethings up when you can hear that :) i noticed a pretty big different in sound, and boost creep haha. enjoy it :D

I have a full 3" megan setup turbo backs on the silvia.

wow is right.

i put a three inch turboback and new ported 02 housing on, havent driven the car yet since she is somewhat quasi dead for the time being. :-( i hate you.
