i have the qtp on my car and its fun when hondas try to mess with you and then you open it up and rev back. they never look over again. :rotfl:

yea im interested in getting one too..but not too many people with subarus have them...could this be a tuning issue?

That's what I'm worried about and especially back pressure and not burning everything out cleanly.

im assuming faster on freeway in high rpms, and not as good at slower speeds? i dont know

yeah tuning wise im clueless... i just want to hear/feel my car

i dont even know about sensors or anything in the exhaust, like if it would throw a check engine light.

my borla with welded silencer put on by previous owner is just too quiet

yes I believe there is a tuning issue because I met a guy around my area with a cut out and he said his tuner (mike) had troubles tuning his car. But this was way way way back then. ewg and cutout abou tthe same sound

I have the QTP cut out down pipe mated to a s*rs cat back. they run about $550 with shipping. 2 problems I've had with it is 1) It's a divorced wastegate and the plate that seperates the 2 exhaust ports got in the way of the wastegate fully opening and I ran uber boost and hit fuel cut a few times before I found out what was wrong...easy fix, just dremmeled it a little thinner in the middle and cut a little notch in the top to let the wastegate swing by. 2) after a while of opening and closing the valve it doesnt close as tight because of the over-torque. it's hard to not do this. but I only use it at the track so a little rvt around the bottom half keeps it nice and tight. You can tell a major difference in hp/tq. spools alot faster and if you do use it on the hwy practically no lag. but it does get annoyingly loud after a while

its going to be like running an open downpipe, which gives you less low end torque. yes, LESS low end torque

oh, and supposedly they break pretty frequently.

i've heard it in person, hella loud.

I had one, car was slower. went from 13.3-13.4 to 13.6-13.7 consistantly. took it offand bought a new down pipe and am right back to 13.3s again. waste of the money spent on the cut-out and my stromug dp. by the way its forsale pm me to buy it.

i had one and i notice it got faster when its open (13.6-13.9) and close (14.3-14.5).

mine wasnt that loud was it? or maybe it was loud because the car was in the garage.

i have one and feel like i dont have as much power from a stop. but on the freeway it feels like i have more power.

I would think you'd need a custom tune to reap the benefits.


Also...wouldnt this lead to boost creep for the STi ?

pros: 10 whp and 16 ft/lbs torque more when open

just got tunned with it closed. im told that having a tune with it open i will see even bigger gains
