Cat replacement pipe with electric cutout?
1991 Camaro Z28 vert 5.0 M5. Only current modification is a Borla catback. I am planning to remove the air injection system and replace the catalytic convertor with a straight pipe. I am also interested in an electric cutout. Does anyone manufacture that combination in a bolt in configuration? I know I could make what I want but I am 71 and would prefer to find it already manufactured. (Yes, I understand the legal and resale ramifications of what I plan to do.)

I do not believe there is a premade version

Race Ready Performance has what you need. Great company to do business with. They take great pride/quality in their cutouts. HTH's

Thanks for the referral. I think I may combine these two and see how that works.

Where did you get that test pipe from? I have wanted to remove my cat and have not been able to find a pipe with the flange to connect to the exhaust. Thanks.

I found it on eBay here but apparently I bought the last one.

Re: Cat replacement pipe with electric cutout?
I just noticed that the eBay seller has listed two more of these pipes here if you are still interested.

Re: Cat replacement pipe with electric cutout?
I had a Quick Time Performance cutout installed years ago, pretty sure it came with a mini Y pipe too, you could probably get something similar and have a shop put the flange on so it'll bolt up
