SLP 1 3/4" headers
Y-pipe is sold.
These have barely any miles on them. They are the non-AIR style, stainless steel, and yes they're the 1.75" primary model. These have not been clearanced for the steering shaft, or modified in any way.
Can accept credit cards through Google Checkout, or money orders.
$175 shipped

Re: SLP 1 3/4" headers/dual 2.5" pipes/bolt in test pipes
Complete setup from my 1991 Formula 350. Swapping in an LS1.
These have barely any miles on them. They are the non-AIR style, stainless steel, and yes they're the 1.75" primary model. Also, I didn't like how SLP's y-pipe necked down to 2.25" so these have custom 2.5" pipes. Includes the proper length allen head-bolts and reusable aluminum collector gaskets. Using red RTV and aluminum gaskets, these never leaked. You will want to purchase new header gaskets of your choice.
These have not been clearanced for the steering shaft, or modified in any way. There is a second O2 sensor bung on the passenger side pipe, intended for a wideband sensor, or could be used in an OBD2 setup.
From SLP, you would have only been given the pipes going from the headers to the front of the cats. As you can see in the pic, this is a dual cat setup with dual bolt in test pipes. The Y-pipe is a Flowmaster 2.5 to 3.5". The intermediate pipe is not included so the exhaust will be cut after the merge.
PM with questions. Can ship, buyer pays shipping. Can accept credit cards through Google Checkout, or money orders.
$600

Re: SLP 1 3/4" headers/dual 2.5" pipes/bolt in test pipes
I will separate if I have buyers for both parts. We can work that out.
They performed great. Why I'm selling them has nothing to do with the headers themselves.

Re: SLP 1 3/4" headers
Payment sent for headers.
Do you happen to still have the header bolts? I know SLP used like 3 different length 3/8" bolts rather than normal header bolts.

Re: SLP 1 3/4" headers
I do and they will be sent with the headers. They are all odd lengths and are allen head with lock washers.
