New exhaust system with 3 "cutouts

[aafc]

While my ECM and chip are out being tested, i removed my power effects
exhaust system. Then installed a stock LT1 system with factory mufflers
with H pipe and added 3" cutouts. I have not tried it as the ECM and chip
won't be tested until Monday or later this week.

That's what I did with my '95. After testing probably a half dozen systems over 20 years on two cars, and mostly using Corsas, I went back to a stock system with electric QTP cutouts. At first I placed them where you did and removed the spare carrier. Then decided I wanted my spare so had Marc H move them to right in front of the mufflers. Have a rocker switch hidden under the carpet on the passenger side of the console. Here are a couple of pix--Bob

interesting...
does a stock LT-1 Exhaust system bolt right up?

I do not have a sound clip of the new system with cutouts,working on it.
The stock LT1 exhaust will work just get one that was used on a manual
transmission. Ii should have all the parts you need. Not sure if a lt1
system used on an auto transmission will work.
When i made my system i only needed the exhaust pipes from the resonator
back. My system uses Jeal headers no cats to 2 3/4 in H-pipe to the stock
2 5/8 in lt1 system. Cut outs are open/closed with a key fob.
my LT1 system came off a 1995 car.

Bob had an awesome ZR1 set-up with his Cut Outs. OP, I'm curious why not go with Corsa then add Cut Outs?

C4RAY,
I brought my car in April 1994 and install the power effects system
in AUG. 1997. Never tried any other system, removed PE system Feb.
2016 and installed the LT1 from a 1995 C4. Now my exhaust system
consists JEAL headers, 2 3/4 in H pipe connected to 2 5/8 in LT1 mufflers
with the 3in cutouts. To sort of hide the cutouts i painted the parts with
high temp header paint. The PE system (resonator rear pipe and mufflers)
are for sale. Prefer local sale, do not know what shipping would be.
