Hey! First off all, this forum is dead that's why you didn't get any response haha. For info and help on the 2nd Gen, check out the "Second Gen Prelude Owners Worldwide" group on Facebook.
There are no exhaust system available for the 2nd gen. Same as with any other aftermarket part lol. There is one header option "OBX"....ebay headers. Quality is fine but the hang really low, so if your Lude is lowered they aren't a option.
If you want an exhaust custom is the way to go. Just go to an exhaust shop an let them make you one. 2" is a good size if your engine is stock. going up wit modifications 2.25, 2.5....3" is the maximum I would put on a 2nd gen, but only of the engine is heavily modified.
I am just occasionly looking on here to redirect lost soules to the facebook group👻
