PPE Engineering Equal Length Headers for the LC500
 

PPE Engineering has just finished up their equal length headers for the LC500.

304 Stainless
Equal Length
100% TIG welded
Parallel Merge Collectors
NIC Glacier Black High Temp Ceramic Coating
*Made in USA

These shots courtesy of PPE Engineering are of my friend's car with the headers installed. My car is set for installation of PPE's catless mid-pipe and these headers next week. PPE will be running my car on the dyno with some numbers to post. I'll get video clips as well. Finally, the LC will get that needed bump in HP and torque that it needs to get it's fat ass moving LOL. I think seeing 520-540 crank HP shoudln't be an issue with supporting bolt-ons in addition to these awesome headers. Add a little 93+ octane and I think the LC will be a little more fun to drive than stock. For more information please contact:

Looking forward to the video and the dyno results!!!

Only thing now, is finding a good performance garage here in Central Florida...

Virginia as well might have to go up to PA and see RRRacing

UPDATE***

Baseline dyno SAE corrected on a Dynojet with Boost Logic Intakes and Tom's Titan Axle-back my LC500 made 400whp in 5th gear. PPE Engineering has just finished up installing their equal length headers and catless/non-resonated mid-pipe and the car goes back for final dyno testing today. I would like to see 450whp but I think it's just wishful thinking we'll see.

Do you have a picture of the factory exhaust manifolds? Just curious what they look like.

Thanks!

I'm curious if after installation were there any engine codes / check engine lights generated. Did there need to be a 'tune' applied to the car to take advantage of the headers?

Mucha Gracias!

I can get a photo of those and post.

Just picked up car today and no CEL. No tune is required as the ECU can make the necessary adjustments.

DYNO RESULTS ARE IN***

Satisfied or no? I feel like that's a bit down for exhaust/headers/tune. Bit nonetheless, a ton of power to the wheels. WevWe just seen I/H/E/T isf's making 420-425 to the wheel, and that's with already giving up 50+ hp to the rcf/LC500.
anyhow, you thanks for being one of the first to do this and share your results!!

^^^^No tune! Don't believe there is one for the LC!

Lou

to help put the dyno in context, this LC500 already had a Tom's axleback and intake installed. So it was up about 18-20 Hp from stock on the baseline run.

on the same dyno, an RCF dynoed 377 max stock run. The same RCF dynoed 418 max with our headers and exhaust installed (no tune). Same numbers as the LC500

So doing headers and exhaust on the LC500 should net about the same power gains. About 40-45whp gain

RR Tune officially has RCF at 442 whp with header/exhaust + tune (no intake). 450+ whp with intake included. Some of it can be attributed due to different dynos being calibrated differently (Mustang vs Dynojet) or SAE correction etc. Our RCF stock exhaust is deplorable for a high performance sports/touring car. About 1.5 inch in diameter with a nasty 90 degree turn before the mufflers.

Lou, you're absolutely correct. Due to the LC not being able to be tuned I feel the ECU is running a bit rich with catless mid-pipe and headers once we can get the files for the ECU on the LC it's game on. With tuning it will yield that extra 20 or so hp left for those bolt-ons that we are not seeing on the dyno here.

After doing some research it seems that the 21" wheels are part of the reason for such a low reading on the dyno. The IS-F come stock with 19" wheels this may explain why they are reading higher on the dyno than the LC with similar bolt-ons. However, my LC has no tune as there aren't any available as of yet, and this would also explain why it lacked a little on the dyno.
