I have a 1991 GTA. There is no aftermarket exhaust on it yet (except a flowmaster muffler installed by the previous owner).

I am looking at having my Spohn Subframe connectors installed soon. Should I tell the shop to install them in a particular way to avoid possible clearance issues with an aftermarket exhaust system?

Thanks,
Bill

 

If you are planning on putting an aftermarket exhaust on, I would wait to do that before welding in the subframe connectors. Once you weld those things up, there's no getting them off again and you may run into problems with the exhaust clearance... particularly the catalytic convertor.

Subframe connectors are a great help to the rigidity of the car, but most thirdgens have been running without them for years. Waiting a little longer to put them on won't hurt anything.

 

 

Then help me find a new exhaust!

I'll move this to a new discussion.

 

I didn't have any problems mounting the SFCs with 2055's - until I put new poly engine mounts in. It isn't the cat, it's the y-pipe that gets close to the SFC.

I ended up cutting the side SFC beam to give the y-pipe clearance, then reboxed the beam by flipping over the cut out piece to close it back up. An unexpected hassle, but really not that big of a deal.

 

i welded my sbfc's in then i did the custom exhaust. its a lot easier to bend exhaust pipe then it is to remove part of the sbfc's.

 

I'd do SFCs and then exhaust for sure.

And Nate86, you can get them off again. Nothing a grinder and a sawzall won't fix

 

Yeah, but who really wants to do that?

 

I would definately do the SFCs first as most of them are designed
to go in where they should.

If having the Exhaust done as custom it can be easily adjusted
as to clearance issues

Just my 2 centavos

I agree with doing the SFC's first, that way you can build your exhaust to fit (not hack at your SFC to make it fit - like me).

I had to remove my Y-pipe to put the SFC on, just to find out that the SFC had to be notched to fit the exhaust when I put the Y-pipe back on. Not too big of a deal, just more work than necessary.
