hey all,

i have read here that several people have put flowmasters on their caddy's. so i am wondering, what is the part number or size that i need for a 98 sts?
my ride isn't listed on their website.

thanx,
rash

You'll have to go with universal mufflers if you want flowmaster. Corsa makes a catback exhaust for STSes but I'm not sure if it covers your year, and it's nearly $1000. Other than that you'll have to go with universal mufflers. I went with magnaflows. The only thing that's necissary is that the mufflers have an offset inlet and center outlet - you can use any case-size muffler, and any size pipe with pipe adaptors, I believe it's 1 7/8" or 2" if you don't want to use adaptors. Magnaflows > Flowmaster anyway.
