I have a few friends with turbos.. and some have gone the route of doing the exhaust cutout trick.. there is a shop around here local that does a NICE job of doing it... just wonderin if there are in horror stories or anything? i saw it and heard it done on an msp.. was nice.. and its ALOT cheaper then buying a turbo back.. i was jyst going to get the s pipe and buy another oem jpipe and let them do the cutout... worth doing or no? thanks
 
i have vibrant's 3" spipe back and i just had an electronic cutout put on last night, so far i like it alot. since my exhaust was already upgraded I didnt see any huge gains but i can tell it pulls harder. i dropped it one time and definitely smoked more than previously, through 1st, 2nd and i let off in 3rd. it sounds bad ass, but i recommend doing an electronic cutout so you can close it when you want easily. check out dmhperformance.com good prices, shipped uber fast and good quality/ easy to install. since i just got it on last night i havent had time to make any film of it, but it is in the plans so you can see it out.
 
velocifero could you post some pics of the cutout when you get a chance, thanks man. I just seached the dmhperformance.com website. I've been researching cutouts for a little while so thanks for the link. When i was running open downpipe 4th gear pulled like a bastard..haha good times.
 
i run a cutout almost 24/7. been doing so since the summer of last year. i did it after hearing equinox, discreetspeed and citizenpro all running cutouts. whenever i close it up i feel so slow, theres quite a difference. i would HIGHLY recommend getting an electronic one though. i just installed a manual one right after the downpipe so whenever cops are around i always have to shove it in to top gear to keep her a lil quieter or just coast around till the po po is gone. its damn loud. and probably illigal in every state (it is in mine). heres some videos for your viewing pleasure. i LOVE my sound. plus i get a HELL of a ot less civics and other smaller cars trying to race me. i guess they all feel intimidated. and everyone always looks at me when im driving down the road.

I just read a post where a guy with the unichip and either SMIC or FMIC gained about 9whp with it open. He had stock cat-back, but bigger mid-pipe... can't remember where the post was, but I think it's worth it. I have the QTP and LOVE it. I keep it closed 99% of the time, but the sound alone it worth the money.

I plan on getting a qtp electric cut out once i save up some cash.
i was debating QTP as well, I really didn't like the switch they provide with theirs, it is a toggle switch, where DMH used a flat rocker switch. Just my two cents that if you get the QTP, ask for another switch or wire on a new switch yourself it looks real cheesy. I also liked DMH because for $20 extra you get the Race Ready cutout, and for the 3" Race Ready at Summit it was like $56. I know jack about welding so I went to a local fabrication shop and we worked it out together. I'll be sure to get some pics and a nice little video up as soon as I have some free time after work, since yesterday I have been running around like crazy.

EDIT: i looked at QTPs site and I see they also have a digital controller, that looks pretty nice and it does some pretty nifty things for you. Either way any body goes I think you'll be happy with it, as long as installed correctly. Don't be fooled though, it is real friggin loud! I had two brothers bouncing away to some loud music in a car next to me and they couldn't hear me at idle then when I accerated their heads just snapped over instantly, it was a classic look that I wish I had a camera on it. You get looks from truckers and just about everbody.

QTP switch isn't that bad.... You hold it for 5 seconds to open or close it and it's dimly lit, so at rest it's yellowish, when you open it, the light turns green and red when you close it. It's not very pretty, but it gets the job done.
 
I am not saying the switch is faulty, just not my style and doesnt flow with the interior of the car. In case we are looking at different pictures here is the DMH and QTP from the Summit website. I also like the adjustable direction you can turn the DMH at the mounting points, it made it a little easier to position mine under the car. I am not bashing anything here, just dont like the switch. I know QTP is quality, they have been around for a while and a lot of other car makes trust them.

So this is just like running open dp.


Is there anything wrong with just unbolting your echaust from your dp and running open dp. I want get my car dyno'd and I think I might do that before I go to get a little extra power.

There is nothing wrong about being open dp... problem is that if a cop is nearby you won't be able to close it and get the noise level back to stock, unlike a cutout.

But if you want to try it on a dyno, yeah, sure.
 
i think i am going to have the shop do this.. better then spending 1200 on an exhaust.. ha ha now do you think i should get teh S and jpipe aftermarket? or say forget it and just leave those stock? thats my next decision.. i want the exhaust cutout.. but THe S and J pipe.. what to do what to do
 
wont an electric cut out give you a CEL?? and then dont CEL's kinda hinder performance by kinda limiting everything on the car bc the computer thinks something is wrong.
 
No you shouldn't trigger a CEL, I've heard of people running the O2 just hanging but I personally don't know any of them. I have no cats on my car and still don't trigger a CEL. Yeah an S pipe upgrade would be a great idea.
