Custom LS y-pipe

Had a 86 camaro come in for exhaust. I never get to do them it was like a little treat. Had Chinese headers on it and I forgot the name of them, never heard of them.

Nice, clean job you did. I wish I had exhaust shops like that around here.

02 sensor hit trans so I had to move it back a bit.

Used this summit connection after the y for removal.

Pretty good ground clearance

Re: Custom LS y-pipe

Nice work, this is what I plan on doing to mine since I have an otherwise mind 3' catback still on the car following my swap. What size "catback" was that? 3", 4"?

Re: Custom LS y-pipe


It’s a 2 3/4 dynomax cat back. I had to swell it to fit the coupler. I’m trying to get him to do a 3” with a single in single out magnaflow.
