i was just thinking about asking the same thing. more specifically, is the QTEC Y pipe (with dual electronic cut outs) worth it. it's about twice as much as other Y pipes out there.

Yes a cut out is worth it, I went through 3 Q-techs before I gave up on them and just use the good old lay on your back to open it up method. If I could do it all over again I would just get the $20 manual open/close cut out.

I liked mine, went to a different exhaust and may not need one now...it only gets rid of about 35% of exhuast flow when placed typically in the rear of Y pipe prior to catback (per kooks)...I noticed a lot of exhaust coming through stock rear exhaust when open...lots louder and definately a difference on the bottle!

Yes it is it will always be there unless ya knock it off. And ya can open and close it at will! What even the mood.Shoot ya can even go to the track and do back to back runs one open and one closed and see the difference if none ya got a good noise maker!

I gained 5 hp open vs closed with my cut-out that is located right in front of the muffler. You might gain a smidge more if your cut-out is in the I pipe, just be harder to get to. Mine cost me something like 15-20 bucks and about 3-4 hours of cutting, grinding and welding,,,,, five hp for 20 bucks.

well after my previous car with all bolt ons and cam and true duals I was very irritated with the sound always droning. I loved it when I wanted lots of noise, but most of the time cruising I wanted to hear my stereo loud and clear but couldn't becuae it was always loud. Now with my current car I will not put true duals on and I have installed a cutout, and its much better. I can turn of the volume at will, sometimes I like to hear it with the stereo jamming other times without the stereo and other times I just want zero noise, so with the stock exhaust i have the best of both worlds. I would never do anything else but the electric cutout its much more fun. I really don't notice any real difference with it open, just louder, but its still worth the money. Of course it does make a difference, but the 10 or so horsepower is hard to feel, but every little bit helps. Mine seems to run perfectly as well-no problems.

Cutout it's the best one of Borla catback and X-pip. Cutout will be better if you put it closer to the rear end. it's so easy to see 5-10 rwhp after the cutout and the right place.

been there, done that, and got rid of it. if you are doing it for the sound. great. as one guy said, he gained a tenth. i gained squat for the 1/4 mile. then i put the bassani tru-dual on and gained .3 and 3 mph. stock vs open was same day back to back.
This is with 200 n2o.
distance ---stock ----- cutout ------ Bassani
60ft ------ 1.987 ------ 2.074 ------ 1.969
1/8 ------- 7.902 ------ 7.912 ------ 7.739
mph ------ 93.20 ------ 93.97 ------ 98.60
1/4 ------ 12.102 ---- 12.080 ------ 11.814
mph ------ 117.12 ---- 118.06 ----- 121.35
i did gain 11/13 on the dyno. but that was AFTER 3200 rpms. dynoing didn't show what happened UNDER 3000rpms.

Well, I do kind of want it for the sound, and for $35 it couldn't hurt to throw a manual one in there and see how I like it before committing to a QTP. Next time I have the thing up in the air I'll look for a place to put it under there (I have a truck BTW).
