Not sure if you bought the stainless model or not, but you should put some anti-seize on the allen bolts. I had a stainless version years ago on my '91 Escort GT. Looked great, sounded great, but the innards rusted out completely after a year. The stainless exterior looked great though!

Funny thing was, when I hung the original exhaust back on, the performance of the car got better. Dumb sometimes how a louder exhaust makes you think that you've suddenly gained 50 hp. That original aluminized steel Ford/Mazda exhaust was tight and rust free after nearly 10 years and 233,000 miles.
