Short or Long tube headers??
Short or Long tube headers?? I have a 98 camaro z28 A4 and i wanted to get long tube headers. My problem is that I live in New York so the car needs to be emissions legal 
. I was told that I can use shorties and still use the factory cats. I wanted to go with long tubes but there is a $$$ issue. Is there a cheap way to use long tubes and still be emissions leagal???? Any info is greatly appreciated.

Stock manifolds flow well enough for n/a applications. Expect to see 3-5rwhp from shorties as a maxium.
LT's do scavenge and will produce a lot more power and torque and make a real noticable difference.
Both will work well with FI because scavenging doesn't take place so the lenght is not important, flow rate is and both when used with FI will outflow stock headers.
Technically I believe LT's are illegal in all 50 states because they change the stock location of the cats. Most inspection places here in PA will pass you as long as you have cats and are not throwing codes even though going by the letter of the law they are not street legal. Not sure how strict NY inspection folks are but I know there are guys here in NY running LT's on the street so at least someone is passing them
