    Does a 95 z28 have O2 sensors on the catalytic converters?

    Question is in the title (disregard the illegalness of that), also, Im looking in to electric cut outs. Are there are kits you guys would recommend?

    Also are there any drawbacks to removing the catalytic converter and replacing with straight pipes? I've heard that it lessens the torque because of the lack of back pressure. If I get the straight pipes, I'm most likely going to put cut outs on then.

    Finally are there any other cheap mods I can do? Thanks

    95 should not have a O2 sensor past the cat cos its OBD1. As far as losing torque, maybe but you're not gonna notice much; cos you'll prob be concentrating more on the sound if you put a cutout there! lol. You could replace the cat with a straight pipe and put a cutout in the usual place under the pass rear seat area. You can either get the electric cutout kit from a place like QTP or just get the simple cutout for like $35 and crawl underneath to pop the cap off when you need to and get the electrical stuff later when your budget allows. If you do that though, Just make sure the cutout isn't welded tucked too far into the body cos you may not be able to clear the electric part of it when you get it. So in essence, get the whole thing together hahaha
    I like work. It fascinates me. I can sit and look at it for hours.

    DMH makes a nice cutout. You can check it out on KY Speed's site: DMH Cutout

    It appears that your car is OBD-II from the info I just read. You can go to OBD-II to see the list of cars. Looks like '94 to '96 were the transition years to OBD-II

    It probably IS OBD-I 'cos it's a '95. Even though a '95 may have the OBD-II style connector under the dash, it's still a OBD-I with a OBD-I PCM but with a OBD-II style connector. GM didn't roll out OBD-II on the f-body platform till the '96 year (federal mandate) even though they started getting the wiring ready for it in '95. ... so call it a OBD 1.5 if you must ... lol

    '95 is a tricky year and it confuses a LOT of people and if that's what your experience is, then a few OBD-II's slipped through GM's cracks 'cos a larger majority of the '95's are OBD-I

    Correction, looks like 'in '95, LT1's were still OBD-I while the V6's were OBD-II ... http://www.obdii.com/connector.html#dates, look under GM, it only shows the 3.8

    Thanks, so, I shouldn't have a problem right?

    Edit: and do you know where I can get that ~$35 non electric cut out?

    Wiki doesn't sell anything, and he wasn't referring to you.

    ObdII was added to many GM v6 cars durring the middle of the 1994 model years in passenger cars and in the middle of the 95 model years in f-bdoy IIRC..

    OBD-II cars will have 02 sensors after the cats.. But they have no effect other than a catalyist code (SES light) and will not effect an obd-II's performance if removed or tuned out..
