Ive just purchased a 92 l98 G92 car with dual cats about a month ago, and was wondering if the exhaust currently on it is stock. Ive looked under the car, and can see that the two cats have already been removed and straight piped, and that there is a muffler in the back that exits on one side with two tips... not too sure if its stock or not? What did the stock l98 G92 exhaust look like anyway?

Not stock, sounds like it has the SLP catback on it.

Weren't there stock dual tipped exhausts?

Yes, there were stock dual "tips," wich were really rusty turndowns, lol, but none that exited on only one side.

Ah yeah I didn't catch that part.

K guys, after looking at SLP catbacks, I am sure that I have a SLP Catback with straight piped cats. Is this hurting or helping me? My neighbor's got a set of Hooker shorty headers 1 3/4" that hes willing to sell me for 140 bucks, unopened never used. How much more power am I currently gaining from my current exhaust? how muchmore would headers help, and would it be better to just straight pipe the whole damn thing?

Definitely not hurting. Headers help alot on the L98s. The exhaust really sucks. I picked up 25hp and 25 lb-ft from headers and a nicer curve, on a stock engine with dual cats.

It's important to get a header kit with the proper y-pipes on the dual cat cars. You can have them made, but why when you can buy them. I don't know if Hooker makes a kit for dual cat cars so I'm not sure if you can get y-pipes that bolt to the Hookers offered to you. BTW, I don't think Hooker makes 1-3/4" shorties for 3rd gens.

If you're going to straight pipe the whole thing (headers back to tail), just get long tubes and be done with it and run "dual" exhaust all the way back. Heck, if you need to have y-pipes made up, might as well go all the way.

If you're not running cats, then just get the single cat system.
