if you're really making 200whp stock... i'd get your ignition timing checked, a/f curve, and the dyno itself checked... something aint right for you to be making 20whp more than any stock SC400 i've seen (with the pre-vvti motors anyway)

my cars not really stock. all i really have is a air filter put on with a intake adapter. and a exhaust made with 2.5 inch piping from the cats back with any x pipe and some cheap ebay mufflers. i didn't know that it was going to make such a big difference . i also think my car needs a tune up too. it smells like its running hella rich.

i doubt a simple catback added 20whp (especially if it needs a tuneup as you suggest)

though nice job on making the exhaust yourself... we need more DIY-guys here

well it does seem possible with the 400s. i had my 95 sc4 dyno'ed at dyno day in norcal section and i got a 200rwhp/220rwtq with a jic catback. but the problem was, it was runnin pig rich above 4000rpm. at that point it started dipping as low into the 10:1s... and at one point for about 500-750rpm, it dipped below that point, can't say for sure how low since the graph went as low as 10:1.
