Exhaust cut outs?
Did a search and only found 1 or 2 pics and most are on c5 or c6's. Curious if anyone with c4's are running them. Where are they mounted? What brand?
Went to a cruise last night and a 69 Z with a big block had them..sounded awsome!
While my car is loud aready through the exhaust I would love to pull in with the headers opened up.

I think location does present a significant issue. Putting them in that last turn before the mufflers seems the only logical place. But, whether it's there or further upstream, you'll be emitting fumes that could heat the underside of the car.
I wouldn't be crazy about that near the gas tank or under the floorpans.

A friend of mine has the QTP electric cutouts on his 1990 C4. He has had to replace the electric motors once or twice. He said installing the replacement motor was not hard. The exhaust shop installed two mini/short y pipes in the front y pipe. I will try to get some photos for you.

Pics would be great! Does your buddy have headers and/or a manual tranny? I am guessing you'll have more space with a manual tranny.

Also, any exhaust you dump under the car is going to be a ton louder in the car.
