Headers HP and TQ gains
hey i guys im fixing install some headers in my 94Z A4. they are Pacesetter LT's with ORY and LM1. i was wanting to know if anybody had ever dynoed their car after the LT headers and just a catback. see my car is completely stock with the exception of the LM1.

That's strange, we put long tubes on my buddy's L98 Trans Am and you could feel it, not so much down low, but you could really feel it up top. Not necessarily seat of the pants, but we could tell a difference.

When I did MAC midlength headers, Hooker catback, K&N CAI, and MadZ28 Tune I went from 255/290 to 285/320, so 30 rwtq 30 rwhp. This was through a single high flow cat, which probably robbed me of 3-5 HP.
I gained 4 mph in the 1/4 mile
Your results should be close. I am a M6 though, so I maybe gained a couple more HP than a A4 might.

I noticed when I added my headers it definitely helped my top-end, sound was much better... Hooker LTs with 4" ORY to a Magnaflow catback makes my car sound so so so much better.
Btw don't forget o2 extensions so the harness reaches the LTs!

I went from stock manifolds, stock single cat and muff to Kooks LTs with twin cats and true 2.5" duals over the axle and straight thru muffs and went from 236rwhp to 274rwhp with no other changes on the '95 TA

Its hard to put a specific number on those types of things, but you should definitely see some gains. After doing long tubes on my car, there was definitely a SOTP difference.
