SLP (91-91 package parts) Parts Wanted
Hi All,
I am looking for the parts that came in the SLP package available from GM dealers for TPI vehicles in the early 90's. It included a cat back exhaust, tri-y headers, siamesed runners, and a performance chip. I am looking for these parts for a L98 (350 cu. in.) engine. Please let me know if you have one or more of these items for sale. I am willing to pay top dollar for top quality.
Thanks,
Chris

Don't forget to find a SLP header install "kit". It will come with all the proper plug wire shielding and header bolts of all the correct lengths.
Expect a set of tri-y headers to run you $2K. Hold out for a dual cat set if you can.
Also if your car is lowered, the y-pipe will take a mean beating on speed bumps and such to beware, it hangs low. After 10+ years my tri-y y-pipe was half flattened and no one local could fix it.

Oooo, the Accel base is great with the SLP runners, I have that setup. Only slightly needed to modify the base in one tiny spot for the runners to fit perfectly flush with no vacuum leak. I think the passenger rear.

I have the upper and lower SLP intake from a 1991 or 1992 Firehawk. Not sure if they have much value, but back in the day it was one of the better flowing setups for the TPI motors.

Yup, Have a NOS set of tri-Ys with the install kit for dual cats (going on a very special project)
Have to make your own gaskets for the T-ram right now until someone steps up and has them made
