Default Tell me what you think of this idea.

I have been pondering an idea to put on one of those motorized muffler bypass valves on my car. I have been running a Turboxs turbo back catless for quite some time now. I have had to go back to stock twice to bring my car in for transmission work and discovered how much more torque that car has down low, but feels like a slug on top end.

So here is where the "new idea" comes in. The utec has the ability to control the parameters at which an accessory activates. So I could set it up to have the bypass valve open at 3000rpm and WOT. This way I could run the stock muffler and have a semi quiet car, gain some low end torque and still have top end power!


The only two problems I have run into is finding more then one distributor for a motorized bypass valve and if the utec would be able to put enough power out to operate the motor.

If anyone can help me out or tell me why this idea sucks…say something!

sorry this isnt much help...but i have seen on the board a picture of an electronic bypass valve so search search search (hehe good luck finding it though I forgot what forum but i know it exists)

as far as the utec controlling I wouldnt worry too much. if it itself does not have enough power to flip the switch you can always use a relay (which is probably safer for the UTEC anyways)

It's an interesting idea. It sounds like a fun project. Who cares what anyone else thinks, go ahead and do it.

Using the UTEC's solenoid control, it'll be like an on/off switch though. It would be cooler if you could control it across the rev range. If you use the UTECs shift light output you'd atleast have 4 positions.

You will have to use a relay, but I think it's not bad idea. Try it out. Then if it's succesful, sell kits for profit!

The Legacy H-6 has a similar setup.
When You get on it past 3,000 rpm there is a by-pass that goes from the beginning of the muffler and around the otherend.Kinda neat.

I've been looking for a cheep project to do. Haven't "made" anything in a while.

-$179 for the valve
-$129 for another Turboxs race pipe.
-$50-100 for cutting, welding, fabrication
-relay....? not to much.

If it all works out I can sell my turboxs magnaflow muffler and the highflow cat that bought before I went catless to cover the costs and just about break even!

Talking But back on topic...

I think this is an awesome idea.... a tech-twist on an old hot-rodder trick. Don't cars like the Infiniti Q45 use tricks like this as well (the H6 Legacy system sounds pretty cool too)?

Back when JC-Whitney/Warshawski's was still in Chicago, they had a manual version of this basically a "dump pipe" where you twisted a lever/handle from inside the car and it diverted the exhaust away from the resonator/muffler stream and just *OUT* under the car (basically it was a Y-Pipe with a valve in it

you can buy a weld in motorized dump from just about any hot rod mag and im sure dylan could weld it inline...
though, you idea will work, there are some nice kits out there already.
although they are for dual exaust cars It does route the exaust to open dump. Im sure youll have no problem finding someone to buy the extra dump youll likely have left.
