i fabricated this awhile ago but i got my camera stolen so i had to use a cheap little webcam, anyway...this fuckin thing rocks, top end is so opened up. low end leave it closed because of needed backpressure. its hooked up on both a full boost activated switch and a toggle switch in the cab. its insanely loud and i love making ricers cry with it :thumbsup

i routed some more piping onto the dump with some oval tubing and a stainless slash tip to dump out the drivers door

good mod ;-) you dont have to leave it open all the time either

it replaces the stock cat location and its very very easily bolted on in 10 mins, only two wires too...power and ground :thumbsup, for us simpletans

sorry for the crude pics, but you get the idea. its black because im stealth like that :+

dude i love it

the other day some little civic ricers came up and were all eyeballin me, i dont think they liked the open exhaust rev...lmao, they were like :eek...you should really hear it at 7000 rpms man, its insanity

Oh I hear that. I just don't want to be replacing motors on the damn actuator every month. :P

could someone kindly explain to me what this is/what it does? I don't know anything about exhaust stuff.. need to learn, but i haven't yet, so I need an explination... lol

sorry for the dumb question

Hey, would this work on a turbo setup??? Also, how much would you charge to make one of those for someone?? Let me know, I'm interested.

turbo8u does have a turbo :-)

its a bypass for the whole exhaust system. Very nice btw josh......gonna make anymore? hint hint

just curious why you would want a bypass for the entire exhaust system? do you mean that it just releases the exhaust under the egine?
just lets it flow easier, not backing up with pressure or what?

It eliminates the exhaust backpressure at high rpm so the turbo will spool like a mofugga. On non turbo cars the exhaust back pressure is needed for torque. On turbo cars back pressure is needed for power before the turbo spools, and once the turbo spools backpressure is the enemy preventing the turbo from spooling to its maximum potential.

ahh... thx.

I'm in for one of these! How much will you charge to make one for me?

the performance end of it allows exhaust to bypass the muffler which is restrictive, thus giving you better flow and better acceleration in the top end. it does need to stay closed in the lower rpms or you'll have no torque, this is why he was saying to hook it up to a boost activated pressure switch and/or a toggle in the cab. this can be used with or without turbo. and best of all...the "oh shit" expressions you will see from the poor bastard sittin' next to ya will definitely feed the ego a bit, thumbs!!! chris

I want. I need. Turby, how long have you been running this setup and how many times have you activeated the qtec? I am just curious as to the longetivity of the qtec's electronics.

awhile, i have a lot of little crap like this



if you seriously want one, make me an offer. i'm totally up for making some if you really want them. the cutout alone sells for 154.99, and also youd pay for my time and i get damn sweet deals on piping so it wont be to much for that. make me an offer...i think the best way would be for you to get a qtec, and then send it to me with some money

if no ones interested its no loss to me because i didnt think anyone would be interested in the first place

turby, take a sound clip for us man.

Hell yea, if u got a sound clip, I bet everyone would be fighting to get one.

i dont even know how the heck id do that...i dont have a camera that records sound very well, i guess i could stream record on my little webcam thing with my laptop in the car but thats a lot of work, lol

i doubt i'll be able to get sound clips until i get another digi, but it is pretty damn badass sounding wot at about 6000rpms }( brrrrAAAHHHH! PSHHH!

instaspool people, INSTA spool...:D

haha, yup

lol
i think i will have to look into this one...

what did you use to block off the cutoff, and where did you buy it (the electrical valve thing)??

So Josh, did you completely remove the catcon? Once the weather get's warmer, I'm defintely making me one.

btw, for all you new guys. This eliminates the need for a full 3 inch cat back.

lol, josh was banned by thura...

and thats whats so kick ass about it imo, you can have quiet as stock.

Now, we were trying to determine if this will have issues with running lean. I dont see why it would, but i thought i read something about it forever ago, any insight?

Okay, so if I were to buy one of these little bad ass QTEC's, I would want to buy the 2.25" right? or 2.5"? I'll have the Star kit when I install this toy. What would it be? And also, would it go lean? The O2 is before the QTEC right, so would it have something to do with the exhaust flow or something to that effect? I'm just guessing, I wouldn't think that it would make it run lean, but then again, that's just me, I'm just as curious since you think you heard it somewhere.

there are 2 o2 sensors, the header one, which is the one that measures air/fuel ratios, then the one after the cat which is a "dead" sensor, its just there to see how the cat is doing. that one just turns on your CEL. so, no your air fuel would not be messed up, you will just run faster.
P.S. i think you can take out the header o2 sensor and put a bolt in the opening and have the sensor hang there if you want your car to run richer (i heard that somewhere, im not sure if its true)

You my friend should not give out anymore advice until you know shit, cuz right now you just know Jack. The downstream o2 sensor (on the down pipe) should not be disconnect at all or anytime. This is vital for your ecu to figure how much fuel you'll need in your engine. No ifs, ands or buts about it, especially if you're turbocharged. Your upstream O2 sensor (the one after the cat) monitors the condition of your cat and it will affect your a/f mixture somewhat. If the cat is clogged, the upstream sensor will trip a CEL. What happens when you have a bad cat? Fuel mileage sucks. So the upstream affects the a/f mixture somewhat. The cutout can be either put in between the cat and the downstream o2 sensor or completely replace the cat like Josh did. Either way, some of the exhaust gas still makes it to the upstream O2 sensor, so it won't trip a CEL. If it does, you can just close the flap the cutout.

lol, im not a fucking idiot, and the rear 02 does affect timing we have found.

its a retarted question, i was thinking more of abrubt exhaust change causing problems. I didnt know why and thought I read about it somewhere. But it just doesnt make sence that it would.

Yeah, I thought it would have something to do with the flow of the exhaust, cuz I and a lot of us here don't even have the rear O2. I could see the rear O2 somewhat affecting it going rich or lean like ^ said, but not enough to make a major problem. And uh, I don't tink I'll be taking out my only other O2 sensor, you can try it and tell us what happens if you want though richlo65. It would probably just put a crap load of fuel and flood wouldn't it?

Gah... I'm having an aneurysm here.

First and foremost, "backpressure" does not mean shit. An engine doesn't need backpressure to make torque, otherwise, we would cap the header or turbo, and make an infinite amount of torque.

What we do need in order to make power, is exhaust gas velocity. There are a lot of principles involved, but none of them include backpressure. Do a search here, a lot has been posted about this by myself and others.

Secondly, the downstream O2 sensor is in back. It is down the exhaust stream, relative to the upstream O2 sensor, which lives in front. Let's use the same terms to describe the same things, and this will make more sense for everybody.

You got your upstream and downstream backwards. Upstream ... further up the stream of exhaust ... closer to the source .. so this is the o2 on downpipe. Down stream ... further down the stream of exhaust ... closer to the exhaust exit ... this is the o2 on the exhaust after the catalytic converter.

simple mix up. I wasn't sure what I was thinking. Probably because I was concentrating too hard on trying to remain calm from the stupid post by mr. plug your o2 housing.

It's just like mine turby but I had mine first. And I put the stock exhaust back on so my GS could soundly sleep.

Amen to that, I want to put a stock gst exhaust on mine so I don't have to listen to "bwaaaa bwaaaaa" all the time. I just havn't found a nice sounding exhaust yet. Major headache.
