1 5/8 Street Legal Performance (SLP) Stainless Steel Headers
Pending deal fell through, so these are still available...
This post is for a used pair of 1 5/8 Street Legal Performance (SLP) Stainless Steel Headers for a GM Third Generation F-Body. These will fit a 1982-92 Chevrolet Camaro, Berlinetta, Z28, RS or Pontiac Firebird, Trans Am, GTA with a 305(5.0L) / 350(5.7L) power plant. These headers are compatible with carbureted or fuel injected engines, specifically Tuned Port Injection (TPI), Throttle Body Injection (TBI), or Crossfire Injection (CFI). These headers were installed on my 85 Z28 (355 TPI) for about a year and I ran 12.90s all day long through these headers. SLP makes a quality product that fits incredibly well and performs as advertised. These smog legal/C.A.R.B. approved headers have since been discontinued and are starting to become extremely difficult to find.
Please note in order to achieve the appropriate clearance in relation to the steering column, the #2 tube on the drivers side header needs to be massaged (dented). This is extremely common with this particular F-Body fitment, not only with the SLP product, but several other header manufacturers as well. Additionally the fixed nuts on the collectors have been opened to accept 9/16 x 2 Ύ shoulder bolts. I have found this configuration is much easier to work with when changing collector gaskets. These headers are in remarkable condition and will deliver with everything you need for installation (with exception of the Y-Pipe). Again, this auction does NOT include the Y-Pipe. If you have any questions, please feel free to ask. Good luck!

The 1 5/8" tubes dont need to be dented, only the 1 3/4" headers. And that's only if you dont want to do the easy fix of loosening the bolts to the steering column and sliding it over a 1/4 inch.

I'm surprised these are still for sale. These are good quality headers and will make a substantial horsepower improvement. As the saying goes do your exhaust upgrades first.

The funny thing is that I sold another set of the exact same set of headers back in March for $475 on eBay. These were the absolute best header on the performance aftermarket right up to the point they were discontinued by SLP. James and I went well into the 12s through these headers many times over. Just plain boggles the mind doesnt it?

Dyno Don makes his own custom headers 1 3/4" (with no denting required) and a custom Y=pipe. They are very similar to the SLP only better IMO.
Since I never heard back I'm guessing it's a no to the offer.
