It's actually not horrible to do headers with the engine still in, though it takes some patience. It is much easier to do when the engine is out, which is how we did it in this build.evan_aggie wrote:Hey Honad, you put on headers if I'm not mistaken, right?
I had a couple of questions.
Most people say headers on the NA w/o the motor pulled is a huge PITA, but do able. How did you install the headers?
Second, what exhaust did you go with? Is the exhaust not effective without the headers, or can you still get gains?
I was looking at the Labree H-pipe with resonators. I wanted some more "gusto" without an obnoxiously loud exhaust.
The car has Specialty Z Test Pipes and non-resonated Greddy SP exhaust. It sounds like f'ing crap between 2k and 4k rpms as it's raspy, from 4k to 7k it sounds great.
I did the full exhaust all at once, so I'm not sure what the power gains were with just headers, but knowing how it worked with other Z's in the area, you will pick up some power when you add Catback, and then again when you add test pipes and again when you add headers. Often I recommend doing Pop charger, Exhaust and ECU before doing anything else. I had some really f'ed up Air/Fuel before I changed Eproms.
The Labree with H-pipe is what I have on my TT, which is actually moving over to my Slicktop this year, since I'm going to 3" on the Turbo car. I think that's a fantastic choice in exhaust. It's got great bends and very little restriction, plus the fit and finish is fantastic.
Also, get some friggen broadband man! Half the joy of this thread is all the pictures.
