First impressions of 42 draft designs downpipe
Finally got it installed yesterday by the nice folks down at <a href="http://www.matrixintegrated.cc/">Matrix</a>.
Don't have alot of time with it yet, certainly no spirited driving. Temps are down into the 50s here so hard to say if increase in power is cold air or the pipe but it does feel quite good.
Anyway, first impression is it's quiet! From inside the car with windows down I think it's actually quieter than it was before. I have an APR exhaust and it had some droning during engine braking thru 3k rpm, it's pretty much gone now. The exhaust note is a bit growlier at WOT but that's about it.
Windows down and you can hear much more. Throttle blips for downshifts give you a bit of turbo sound and there's an overall throatier sound to the exhaust. I did a flyby past Danielle and she thought it was quite a bit louder outside, going to have to hear for myself on that one
Overall though I'm pretty impressed. I was a bit worried that it might be too loud inside the car with the APR exhaust since I do alot of longer roadtrips but it's very civilized. Two thumbs up so far. Gotta wait and see if there is really additional power there, already lost my first drag race with it installed to a certain blue car, and also waiting to see if I get any CELs.

Power is definitely there - they dyno proved that........
you'll see more increase as the ECU adapts. I'm surprised about your quiter comment though - mine is definitely a bit louder - actually just deeper sounding.

Ah, the cat is terrible in comparison to the testpipe...
in terms of both sound and performance. Granted, the cat is obviously more responsible, and that is an important consideration. I just couldn't bring myself to keep the cat section in after having driven the car with the TP. The differences for me were just too great. I actually miss having the 42DD stuff. The APR dp is really nice, and I'm actually using the 42DD tp (which was shortened by about an inch), but the sound isn't nearly as sweet as this was...<ul><li><a href="http://www.youtube.com/watch?v=7egY5Ma3RVY">I miss this sound</a></li></ul>
