I guess this is how they are building them now Glover997.

Installed, dyno tomorrow:
PPE Long-Tube Header install « J-Rho's '67 Camaro Z28 STX build

Nice write up j-rho. I especially liked the pic of you smiling before the pain :rofl2: If I've said it once, I've said it a thousand times...PPE headers are a major PITA to install especially the driver side.

Kudos for you installing them without removing the engine as did I. BTW, I had to make a wrench to reach/tighten the lower back nut on the driver side header.

Also, my butt dyno could tell the increase in HP after the install. Lastly, on the steering wheel linkage, there's an alignment flat spot on the spline shaft and yoke. That's what I used so I didn't have to go in and re-align.

Great write up! Thanks for posting. It took us a solid 12 hours to install these on the black cherry convertible and it spent most of it's life by the ocean so we had a few f^*@in S*!+ moments.

The dip is a characteristic of the header -- the gains everywhere else more than make up for it tho'. You can minimize it somewhat with VVEL tuning (dial out some overlap in that rev range). Adding in a "choke", such as a single HFC, will flatten it out too -- but you might end up losing a few up top.

We appreciate it when experts come in to talk about these products and share their knowledge. :)

That's because OBX copied PPE's design

OBX is said to be a much poorer quality. For the amount of labor it takes to install these, I'd spend the money to only have to do it once.

Bump - Good looks, solid gains, time consuming install but that SOUND!

Bump - Unleash some pent up power! Let your Z breathe! Lot's of deals this month! PM me for pricing.

All PM's responded to. Thank you for your continued interest, I look forward to assisting all of you further.
