Question for people with LG longtubes and Cats - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Well my question is i just bought some LG longtube headers and cats (thanks Ivan from Sw speed btw) and i just opened the box the other day and looked into and i see the hi flow cats are 3in in and out and is this gonna bolt up to my Flowmaster Outlaw exhaust correctly? I know its a full 3in cat back. Someone told me it wont work and i might have to have it welded on there. I was hoping for a bolt up and get with it.

based on the pics from flowmaster, the outlaw cat back necks down to 2.5 to bolt up to the stock cat pipes....

you will need different connection pipes or a muffler shop to make it work right.

if I were you I would go the muffler shop route and have them make it all 3 inch.

Box should have contained an adapter I believe.

Southwest Speed has great customer service and should be able to help you out.

yup i was missing parts now i gotta wait even longer to get these put on. And does this eliminate the rear o2 sensors? After the cats?

If there's no bung for the rear O2 sensors, then yes it does.
