In an effort to put out the best possible PEMs we've researched and hit a wall. The problem lies in the front header piece. Opening the inlet as people are isn't doing anything because the inlets are already 1.53" (as big as the port in the head). The problem is the lower section of the manifold. It's 2" OD and 1.63" ID. At that section you're sharing with the other ports. Trying to exhaust all 3 front cylinders out of a single 1 5/8" pipe is crazy. It's no wonder so many people pop front pistons and have questionable gains from other PEMs on the market. The rear manifold and crossover aren't as bad. Notice the crossover is also 2" OD, like the front mani, but because it's thin wall you get 1.91 ID. So, the front mani is the narrowest section of the exhaust, giving you 2.09 sq/in of exhaust area. The crossover and rear manifold are up to 2.89 sq/in. So the front manifold section is over 30% smaller than the entire rest of the manifold network and it's the only section that guys selling PEMs aren't doing!

Fortunately ZZPerformance now offers a cost effective solution. The powerlog uses 1 5/8 primaries which feed a 2 1/4" pipe into the crossover. Uses factory mounting, so all the factory bolts and gaskets can be re-used. Excellent for use with our downpipes.

  • No loss in torque as seen with headers on the L36 engines
  • Perfect upgrade for turbo kits
  • Low cost
  • Lowers KR and keeps the front bank of pistons safer.
  • Quicker engine cool downs from eliminating the cast iron
  • Power log is 5 pounds lighter than OEM cast front!
  • Doing the front only gives great gains and takes less than 30 minutes!

 


Over 10WHP gained from the addition of the powerlog and no other changes!
I also wanted to post that I just went through my 1st full tank of gas after the plog (yes I drive a lot) and I have picked up a few MPG as well. About 35-40 miles extra to the tank on the exact same commute as before the plog.
Below is from another member who scanned before and after his powerlog install. Notice how much more timing is achieved and KR eliminated!
Stock front exhaust manifold scan below, as you can see some light KR up top.
Powerlog Added scan this is with the front 3 cylinders skewed with 2% extra fuel. I also added 1-2 degrees extra timing and raised my Base PE by .1 (leaner).

The Powerlog and Ported rear manifold will support up to around 300whp, but for a goal higher than that, we highly recommend our Stainless headers.
Do not wrap these exhaust pieces as cracking can result.

Everything I've gotten from zzp is excellent as far as the power law goes installed very easy and definitely a little noticeable gain In power and throttle response

Front power log with Lava heatshield

Being new to the 3800 platform and given age of these cars and seeing what the masses are that drive these cars "Seniors" or maybe its just Florida lol, I was surprised to see an aftermarket for this platform, So far that parts I've ordered from ZZP have been of good quality and all have fit with no modifications which in the world of Chi-bay is a blessing. I recently installed my power log and despite heeding the advice to not wrap these I just could not get comfortable with the fact of so much heat so close to the Air conditioner high pressure line so I did some research and found that the product I used would not void any warranties and allows the manifold to release some heat avoiding the cracking issue from actual header wrap. Just to mention there is no gasket in-between the header and crossover tube like I thought there was, the 2 pieces compress into each other forming a seal much like AN fittings. I mention this due to the fact when i started the car i had a leak from this area and had to tighten the bolts pretty tightly to stop the leak. Not sure if its in my head but the car cruising feels smoother, doesn't seem like it struggling to breathe out the exhaust. Under spirited driving/launches it feels bit more responsive with a tad more pull in the upper RPM's.

Best thing yet

This was very easy to install and looks amazing under the hood. It did a fantastic job of cleaning up the exhaust note and making it less raspy at higher rpm. The fit and finish of this product is amazing and I can't thank zzp enough for making it affordable and such a fantastic product
