Ive got pacesetters and for the price i spent, i couldnt be happier. I picked up some felpro mani gaskets from AZ for $10. I used these Dynomax Lap-Joint Band Clamps: WLK-33226 - summitracing.com for my y pipe. And i used one of these Percy's Seal-4-Good Collector Gaskets: PHP-66002 - summitracing.com at the collector. You are also gonna need some longer crossover bolts which you can just pick up from the local hardware store. I also just picked up an O2 extension because i didnt feel like hacking away at the O2 sensor wires. Ive had them installed for a little over a month and i have yet to have any sealing problems (knocks on wood ).
