ok so the natural first step was a CAI, K&N. now what would be my next step to beef up my 4th gen 2000 z28. i did 3 1/4 inch flowmasters. now what?

 

A good set of LT headers and a new Y pipe.

 

LT is that the brand or the type? and what is the Y pipe for. like i said i already did flowmasters is that similar?

 

the y-pipe is what joins the outlets on headers or manifolds into one pipe on one side of the car. a bigger diameter y-pipe will aid in exhaust flow and smooth it out, so your not going from say bigger diameter headers to small y-pipe to big pipe to the mufflers.

 

LT stands for "Long Tube." If you put on LT headers you have to get a new Y pipe because you can't connect the collector of the header up to the stock Y pipe location. If you get shortie headers they'll bolt directly up to your stock Y pipe, but then they won't get you anything because the stock Y pipe is known for being extremely restricive.

 

thankyou gentlemen ill have it done by the end of this month if i can, perhaps the beginning of next month
