This is what ya have to do to get them to fit. No, these aren't Flowmasters or mine, but you gotta lay them on their side like this. BTW, I had the 2 chamber 40's on my '99 and when I traded it in on my '00 I missed the rumble so much I had another set on within 2 weeks. If you put them on you'll need (1)2.5" offset inlet/2.5" center outlet and (1) 2.5" center inlet/2.5" center outlet. Beats the hell out of that escort sounding stock muffler. FWIW, they make a dual in/dual out Flowmaster but some guys have complained of a blowing sound while at WOT and others have said they didn't hear it.
