QTP Y-Pipe Cut Out: $150, Welding the piece into car: $75
Look on Mr. Carerra's face after he revs it and I open it and rev: PRICELESS

I've had my QTP for about six months now, no leaks. Only problem I've had was the clearance problem. I've bottomed out on the flange a few times but no major damage has happened so far. I'm untuned but I'm saving up for Ap Stg 2 or the Ecuteck. Power feels much more smoother. Cops haven't noticed it at all...yet. All abd all it has been a very good upgrade and definatly worth the money.

I called today to inquire about the price of the new controller.....$110! Guess Ill stick with the old switch.

Not sure about time but a couple of guys have said they picked up 2-3mph in their trap.

Default VES cut out

does any body else have any information, or experience using this cutout. It seems simple and perfect for the application… closed until boost is reached ideal for minimal backpressure.

Very informative thread- thanks. I'm kicking around the idea of running a few mufflers in my catback section (I'm old and like quiet) and putting a cutout between the two. This would allow my "cutout fury" to still be muffled some. Thoughts?

You could also put a cat and/or resonator before the cutout if you don't have one already. I think a muffler would just cause too much restriction for the cutout to be worth it.

SWEET! It's like a post-turbo External Wastegate haha. I might have to get me one of those!

That unit is really big, and mounting it sideways in the exhaust is a bad idea, to get maximum venting you want it inline with the exhaust flow imo.

Yeah, I find it odd that it is a T intersection instead of a Y like it should be.

Good input. I've been struggling for a long time to find a good balance between flow and quietness. I love the stock, almost silent system on my long trips, but I know I'm killing my performance during every day driving. The loudness of an open cut out without a muffler isn't appealing at all either. I think I just need to run a dual setup with a quiet system on one side and a louder system on the other and a cutout in the middle to switch between them .

I have 2 questions.

1. would running a cutout without a tune be harmful??

2. are there any bolt-on models as opposed to a weld-on?

For my STi, I was running rich to begin with so it wasn't harmful running it without a tune.
QTP makes a bolt in catless downpipe with a cutout built in.

I used it everyday, with no EM, for almost a year. No problems.

Just installed my badlanz 3 inch cutout with the stock catback and absolutely love it. My question is, although it has kind of already been addressed is will my ECU learn with it closed and then make my car run like crap with it open or vise versa...it is a Utec on a stage 4 02 wrx by the way...thanks.

Turbo engines need a back pressure. If you use a catless downpipe with a cutout - you won't get any power at the top end. It's great for start, but sucks for high speeds. Unless you port your turbo. I mean, I loved the sound of my Badlanze cutout, but the fact that when you need an acceleration at 100-120 Mph - and you don't get it, but have a check engine light instead - it's a bitch. I had 3" catless downpipe with a cutout - lots of noise and after I installed a stock cat exhaust - I gained power! I love my STI setup right now - fast and f///king quite! The sport car has to be as quite as possible with a maximum power gain. + Noise gets cop's attention//// Hate them///

Seriously, the only reason I've taken off my 3" cutout downpipe with a cutout - 'cause the ECU was giving me a CEL each time I asked for acceleration on the top end and I had no acceleration when shifted from 5 gear to 3rd... (on high speeds over 100 mph///) Talk to any professional mechanic - anybody will tell you - don't use catless downpipes on turbo engines, once again - it needs a back pressure to slow down when you don't need power and will give you a nice acceleration when you ask for it... cutouts are great for non-turbo cars like Camaro or Corvettes.

You have it backwards.
NA Cars need some back pressure - as so I've heard.
Turbo cars definitely don't need back pressure.
Just think about it, the turbo is blowing out exhaust gases and instead of it being free flow the gases bottleneck at a cat or restrictive muffler, this slows down the overall flow. Having a freer flowing turbo back exhaust lets the turbo work more efficiently since gases can escape faster, decreasing spool up time.

Anybody that has installed a downpipe, or TBE on their turbo car can attest to this.

There is something wrong with your car or setup if you lost power and got a CEL on acceleration with your cutout.

Have you ever heard about boost creep? I'll give you a couple links to it here at NASIOC... You get it even if you only install a catless downpipe... not talking about the cutout//// Give me a minute///
