what would you benefit from that? it straight open doesnt flow 100 percent of the air already

That's pretty inventive! The new C6 z06's have sortof the same thing going on in their mufflers. At 3500 (i think) a trap door opens up and it's straight-thru.

I like people who think about stuff. Almost as good as my old exhaust idea......

It would work,but to an extent,the airflow wouldnt be NEARLY as good as it being off,maybe if you got the right spring tension,and got rid of the threads on the screws so the plate could slide easily....very good idea,but needs more thought


My buddy has a cutout and at slow speeds the exhaust barely goes out the cutout, but when he gets on it,the exhaust rushes through it and is incredibly loud...so in theory,with more thought,your idea could work

I had an idea where at lets say 3800 RPM the cutout would open because as we all know when the cutout is shut we feel more torque until ~3800 where the exaust becomes restrictive. So if you had a cutout that opened up around that time it would be the best of both worlds!

you could find out the surface area of your plate and use that to calculate the spring pressure you would need so that it would open anytime the exhaust built up back pressure and you could even tighten/or loosen the bolts to change the preload. it might be neat since in would idle quiet but open up everytime you needed it that way if somebody pulled up beside you it would be stock quiet and even when you are lined ready to go it would stay quiet right until you took off.

but in I think it would probably leak if you used a weak enough spring that it would actualy open and once you had one strong enough to not leak it might do open enough to help. could idea though and three bolts and springs might cost 3.00 bucks so if you already have the cutout might as well try it when your bored one day.

Guys check this out. You can hook the controller to WOT switch and open it up at WOT or any ground setting.

I like my ~$3 controller idea better if it can get the bugs out, than over $260

gasket sealing would be an issue because when i did do it I blew out the collector gasket. Still workin on it tho

2 bullets PLUS a flowmaster.???????? WHY??? And why put cutouts AFTER the bullet mufflers.??? NOT Knocking you..jus' wondering.

What you have there is a pressure relief valve, you
will always have the springs' force to overcome and
that means a few PSI just to clear the seat, a few
more to get it well cracked open.

I favor the idea of a butterfly cutout with a spring
to open, vacuum biscuit to close on the bellcrank.
Like an old-style cruise control vacuum biscuit.

The cutouts right after the bullets would keep my mean as hell TSP TD's sound when they were open. Close the cutouts and all the gas would be routed to the quiet as hell flowmaster to keep my neighbors windows intact and add to the sleeper-ness.

The situation I was in was that the TSP TD's dumped with bullets were too loud, but I loved the sound. The dual cutouts and extra piping would have given me the best of both worlds. The only problem was that crossover pipe runs right through where the driveshaft/tq arm is lol.

I threw that idea out and went with 2 3" magnaflow cats and had the pipes ran out the back.
