So yes- if you need it, we will sell it to ya. Only after we finalize any design changes that may be necessary.

Just for a clarification- this is a diverter not a cutout in the traditional sense. We use 4 butterflies all in sync which would require 4 'cutouts' and an exhaust plumbing master to pull off. This is the industries only self contained dual butterfly piece that gives you infinate range from full stock to full 100% open header/manifold. "Cutouts" just give exhaust an escape path but your exhaust system still receives alot of noise and energy making them less effective. As we open up our system we are progressively closing off the quiet side completely. Believe me, this makes a huge difference!

The "h" design will allow you to leave every factory hanger/bracket untouched and we just shift the loud stuff to the side.

And- with a recip saw and a 9/16" wrench it should only take 10 - 15 minutes per diverter to BOLT-IN YOURSELF IN YOUR GARAGE with NO WELDING plus whatever time it takes to wire the controller.

so if i want a really quiet muffler on one side and a loud one on the otherside would that be possible? id get my a$$ handed to me by johnny law by having a straight pipes, but i really want to be able to cruise with without going deaf, also if not possible do you get any gain on turbo charged systems by having a cutout?

Is it safe to simply release hot exhaust directly underneath the car?

Correct me if im wrong but are you asking if you can be 50/50?

How it works is both diverters work with each other in sync. However, if you want to open it only 5%, (which usually sounds rediculously cool by the way) then leave it there. if you feel even a little bit more is ok with out getting in trouble give it a little more. With our controller you can even program your favorite SWEET SPOT with the middle button- just push and hold it for 3 seconds - similar to an FM radio preset. Then if you need that perfect "barely legal" tone you love just hit the middle button and it goes exactly back there.

To keep the cars engine and computer happy though we want equal pressure on each side so both diverters do the same thing at the same time.

Safe enough. I've seen a ton of exhaust done that way and had several myself, but safe is a tough word. Heck driving a car isn't "safe."

i was refering to having 2 seperate mufflers like the stock one (or quieter) and a loud one like a flowmaster 40 series on the other side and go one side to the other. or does the partial opening still keep sounds under control

I guess the better question would have been, can it damage anything or cause any long term problems? There has to be a reason why all (stock) cars release exhaust away behind the vehicle...

Technicly speaking the main reason to dump exhaust in the back is to prevent excessive fumes from entering the cabin. Legaly all exhaust must clear the cabin.

A turndown is used in most cases to direct the exhaust to the sides or back based on location of diverter. Directing heat and fumes toward the edges of the car is normally how its installed and should be kept in mind to keep it safe.

More than likely the diverter is going to be right at the front edge of the back tire and the loud open exhaust will be directed either straight back or turned down and out at 45 degree angles. This is approximately where we install on the C5 Z06 and it works amazing back there.

But won't that put the valve behind the cats?

Ok, that makes sense. So then the obvious question is, in your experience (or anyone else's), do you notice a strong exhaust smell when the diverter is engaged?

Sorry for all the questions, but I would definitely consider something like this in the new Camaro.

Partial open will keep things civilized. We have done exactly what you are talking about before though and it does work that way too.

To keep weight down and keep it simple i would try without first- then add second muffler if it 'needs' it. It really is adjustable though. Like a volume knob you can keep bumping it.

It does, but sometimes with engineered floor pans we have limited options. With the 5gallon bucket sized mufflers on this car - im guessing alot of sound is getting back there that they are trying to supress. The cats and resonators are usually very high flowing on these hp cars.

If there is room though- the front is better

Only on a race car because they dont have insulation or weatherstripping and often times have holes for the shifter or cage that let the fumes in.

If the diverters are before the Turbo...you're gonna have serious issues (as in a rear-mount setup)

If they're after the turbo...all I can see you getting is a crazy-loud sound.
