Which Y?

This is the Y-pipe I currently have mated to the Jet Hot LTs on my Firebird. It doesn't have the greatest merge on it, but it tucks up under the body the best of any 3" Aftermarket Y for these cars.
If you can't get your hands on this specific Y, I recommend purchasing a Catted Y from Texas Speed (or a similarly designed Y) and forget you even have cats. High Flow cats affect on performance is minimal at best. You may be giving up 5 HP. Unless you're looking the scrape every pony outta your car, I say find a Y with high flow cats and call it a day.
