Looking at getting a new exhaust system fab'd up for my '92 Loyale, so... a few questions.

1. Is the exhaust from an '87 GL the same as from the '92 Loyale? I'm planning to go with a custom engine-back exhaust, glasspack instead of the cat, etc... and the '87 passes as an "offroad only" vehicle. If it'll bolt right up to the '92, I'll do that.

2. Glasspack instead of the cats, and a good sized muffler in the back - will this be nice and quiet? I'm looking for a fairly non-restrictive, but yet still nearly silent exhaust.

3. What diameter piping should I use for the Y-pipe, and then behind that? This will *actually* be for my '92 Loyale, so it will be used for in town driving, highway cruising, and the occasional rallycross - but mostly in-town & highway, so I'd like low end torque. I seem to recall 1.25" on the y-pipe, and 1.75" from the junction back - does that sound sane?

Other suggestions?

There is a seeming endless possibility for exhaust. By my own reason (if it helps) the factory dimensions right off the heads are great, the junction needs bigger until the "second cat" or resonator,(even if nothing is going there, just use it as a distance) then pipe can go back to oem, even the muffler, as it is cooler by then anyway. Sounds big, not loud. Keeps oem stuff for fuel, etc all good.If high revs for a long time, all the way back with 2" is very good.
