I picked up an exhaust off of a 1996 Z34 from the junk yard for 45 bucks. I have a 1998 LS with the 3.1L engine. Would this be a direct fit onto my Monte? If so, would this cause any problems from putting this 3.4L exhaust on my 3.1L?

 

If it's just the catback I'd assume it'll bolt right up.
Nice find.

 

As long as the flange on the catback is the same as the flange on your downpipe, everything else will fit. Did you grab the hangers from the drivers side muffler off the Z34?

 

It should fit no problem, may just need a hanger or two

 

Oops. I forgot to get the hangers. I will have to make a trip up to Auto Zone to get the hangers. Thanks for the info guys!

 

If you're getting it welded on, the welder shouldn't have an issue with adding some hangers

 

There shouldnt be any welding required. The hanger for the driver side muffler should unbolt from the car. Get the hanger and the two rubbers and everything else should be a direct fit. I ask about the flange on the DP because different year Z34s use different flanges on the DP from what I have read. I would check to be 100% sure it fits.

 

Great find Best way to get dual exhaust!

 

I got it put on with some universal exhaust hangers but the are pretty crappy so I will pick up the original Z34 exhaust hangers next time I get to the junk yard. The down pipe has a different flange which is a little off but it will work for now until I can get to a muffler shop to swap the connector. Here are a couple of picture of what it looks like so far. The driver side is hanging down a little farther than it should be because of the universal hanger that does not fit right. Not too bad for the price I paid for it...

 

Please don't hold the ugliness of the paint work against me! Haha! It will be headed to the paint shop once I get the body flaws worked out.
