Pros: It's the ultimate sleeper. It sounds badass when you're opening it or closing it. It's super loud then all of a sudden it's quiet. Let you have a stock sound when you're cruising with a hot chick in the passenger's seat.

Cons: It leaks when it's closed so it sounds like you have a good sized exhaust leak.

also, if the rest of your exhaust is stock (ie. moderately restrictive) then switching back and forth often may "confuse" the ecu. for example, the first time i took off my oem muffler, the car didn't really start responding to the lower backpressure until i did about a day's worth of driving... then it definitely came alive.

it's not like it will do any damage, but you probably won't be able to open the cutout and immediately reap ALL the benefits (at least not without an ecu reset and a shiv iam trick).

The only real down sides I could see would be if you place it before your rear o2 sensor and don't run a resistor. You'd run the risk of throwing a check engine light when the cutout was open. Also, if the cutout were to start leaking then that would suck as well. The cutout I bought and compared to others on the market looks to be much better manufactured and doesn't leak as of yet. I've also talked with a few guys running the same cut out for close to 3+ years and they have had no problems with operation or leaking.

D-I-Z-Z-L-E, has a short clip of his car with his cut out. It's pretty cool. PM him and I am sure he will send it your way!

Cool

With my vf22 and MBC, It surprised me to see it jump 2 psi in boost when I unhooked the catback for a test run.
With the stock ECU, it hit the fuel cut and gave me a CEL.

So if you were to use a cutout, you would have to have an EBC.

a chronic problem i saw on other boards was that the servos didn't really hold up to the normal abuse of daily driving. kind of an expensive part for it to not last very long.

although you don't hear about the "mine's lasted me 100k miles in perfect shape" cases nearly as often, now do you?

Electric cutouts are the ****!!!! I have one on my car and love it. One of my biggest sponsors, Quick Time Performance, is the provider of my cutout as well as the cutouts on several of the cars we put together at our shop! Go to the website, www.quicktimeperformance.com , or call and talk to Barry! You cant go wrong, this is an A+ product and it will scare the **** out of people when you open it at a stop light and rev on someone who just reved up on you!! Again, go to the website and see the sound clips that are available and check out Barrys' WRX!!!!

I have one and i love it. I think it works very well. The unit i have is from Quick Time Performance, it is their QTEC. It is a great product, well manufactured, and worth the price. Check out the link below

I hate saying bad things about companies online...but the QTech was the main other cutout I compared mine against. The DMH unit is MUCH better quality. Hell, my friends that have them on their F-Bodies are getting ready to pull their QTecks off and get the DMHs.

the one CON that I see is that when the cut-out is closed, there is just that open pocket. By that I mean there is a pipe section with no exit. That small section creats turbulence in the exhaust stream...so unless you're running this thing open all the time, I've gotta assume that you're losing a little bit of power...not alot, but a little bit...

BTW...it sounded AWESOME!!!!

DO NOT BUY A CUT OUT

I bought a QuickTime Performance cutout, and the leak that it gave when closed was so annoying... it sounded horrible. Sounded like a constant hub hub hub, the sound of a beat up car. The best thing i suggest to you is, keep the stock muffler, and have the rest redone. Do it yourself, i did mine, and it's very quiet. I mean is it worth it, loudnoise all the time, or even a little hum all the time (subaru sound isnt all great unless you're opendownpipe, that sounds freaking mean as hell)? 5 hp at the best, o.k. to be on the conservative, actually ridiculous, 10 hp lesss? So what, exhaust isn't everything. 10 hp correlates to what, .1 off your quarter?

I have a few friends with the QTP and theirs have already broken on them. I run the McCord, which I bought used, and it's been going good for about 6 months. Yes, it does leak and it is very very annoying, but I hate the droning sound of an exhaust on the freeway. The only thing is that the cutout has seen many speed bumps.. so I believe it's on it's way out. It takes 8 seconds to open up now instead of the usual 4.. and it hesitates when I'm trying to open it.
