Get some nice headers and a good exhaust and it will sound great, make some power and not sound like a Ricers car. I have S-Car-Go headers and Mille Migla exhaust. Trust me it is plenty loud enough.

Though they are quite expensive, my Supersprint sounds sooooooooo sweet. Esp when I added the intake. The combo of the two sounds is just SHWING!!!!!! Keep an eye out and you can get a smokin' deal on one.

Lets see, gives 9 more hp, and makes the car 30 pounds lighter. Definately worth the money if you can't build it yourself. It's still street legal and removes the secondary set of cats. Ever heard a car with the cats removed? VERY LOUD! I just thought it was a easier alternative compared to the first post with the bi-pass valve video.

true, less wait and 9 hp count for something. Do 1997's have 4 cats? when i was under the car i didnt see but only 1 cat per side. If i have 4 cats total, i can have some little mexican muffler shop do it for 50 bucks.

As far as I know, yes. All of them have 2 sets = 4 cats. Stupid and no reason for 4 sets. Two are built onto the headers and 2 after just before the mufler(the ones you can easily see). If you use some shop to get rid of the 2 before the exhuast/mufler, then you still will need the bung-hole for the sensors to go in. How are they going to do that? That's why I posted that link. It has holes(one for each pipe) made to hold the factory sensor, making it still street legal and able to pass emitions.

hmmm whatever will do i, im curling up into fetal posistion cause i know not what to do........ oh wait, i can buy 2 anti-foulers from autozone for 5 bucks, have the shop drill a hole in the new pipe and screw in then weld the anti-fouler/o2 bung-hole... its not rocket science.

I agree that these parts are completely over priced. If you are going to have a shop make an alternative for cheaper than you might want to see if others on the forums are interested and perhaps work out a group deal. I think there were people here who were interested in the bypass pipes if they could get them for 200 or so. Just a thought.
