I am sure you will get mixed opinions on the exhaust and filters - I have a 1996 that i bought used in may of this year had 6900 miles on it stock everything.....i changed the oil/filter, checked the air filter cleaned and put it back in the stock filter box, added a Jardine slash cut muffler that I got used (barely) off craigslist for $50.....it is loud!, probably adds to the backfiring but I like the backfiring and the loud - lets critters & cagers know I 'm there.....I have not re-jetted or done carb work - just the jardine muffler, 50 mpg around town....

For the best sound and performance, the Supertrapp is the best slip on but its expensive. Around $400. Sometimes you can find them on sale for around $250. Expensive but worth the money.
