Probably not. I have the FTRA (Fast Toys Ram Air) which was good for me but I had no air. I would concentrate on the long tubes, stall and catback.

I have heard the same thing about the flowmaster catback not flowing, but I had mine custom done with an 80 series and that worked out. It would not be the first thing I change, again, though.

I hear good things about the new Yank SS3600's and they were the best. When I blew my tranny and ruined their converter. Sent me a new one on charge. Also they will custom build you any converter you want as they are a pretty small shop so there is no such thing as "they don't make it anymore".

If your going to be adding heads and cam I would also be looking into a 12 bolt as these 10 bolts are not known for their durability. Gears in back will make it a bit easier in the quarter but any gear can go if it is matched too the STR of the stall. See below. Although if I had 4:11, a 12 bolt and slicks I would be 10's. I prefer 80 MPH at 2000 RPM being it is a daily driver.

All wheel drive <smack> what you do not think your car is heavy enough now?
