I got PPE Long tube headers installed yesterday along with a fidanza flywheel and SS Clutch Line (another awesome mod !!! )... I was supposed to have a dyno and re tune right after but that was delayed until Tuesday. They did take a baseline dyno before the install though so there will be a before/after comparison.. However, My motor was just changed due to OC, so there are variables that could cause a bigger change in power with the retune. But from driving the he car is def quicker than before and I am expecting to see some nice gains. The shop praised the built quality and said the design looked good. Tuesday it is going back on the dyno and getting the tune tweaked, right now I am running very rich, they said 2 points rich at least.
The one pleasant surprise was that my cars exhuast note is actually MUCH cleaner than before. I went from Berk Test Pipes with Stillen Exhaust to these PPE Long Tube Headers and Stillen exhaust. The car is actually quieter at all rpms with a cleaner sound than before with test pipes. There is less rasp but a more aggressive tone (The pitch of the exhaust changed a little.. for the better ). There is still some rasp along with the lovely hiss but it definatly sounds better than before. I was expecting it to get louder and more raspy and they did the oposite...
My headers were coated and I believe go for around 1,000 on PPE's website. I purchased them used off another forum member a few months back. His Nismo is the car posted on PPE's site with dyno charts giving him 20+ whp , but his car was all stock otherwise...
On a side not, the shop had to drop my motor to get them in. They broke sockets and just decided it would be easier to just drop the motor. Driver's side was a nightmare. Mine was the only 370 that they had to drop the motor for (typical luck of mine) , they installed 4-5 sets of FI LTH without dropping it. But the install IS tough for these... The original quote was very reasonable but went up a smidge because of the motor, but still very reasonable. Money well spent. Performance Motorsports installed these...
So Tuesday I will post before/after dyno charts... but keep these in mind if you are contemplating headers. The biggest plus again is how clean the exhaust sounds.
I am super happy with these and do not regret the purchase or install a bit.
