I just got off of the phone with an SLP customer service representative about clearance issues with their 1 3/4" headers. Here is what I was told:

HIM: One reason that the headers may not fit is due to the engine mounts. Over time the motor mounts may wear which can take up the clearance you need. Replacing them may fix this. If this does not work. We suggest putting a little flat spot in the headers. This will not affect flow.

ME: Are your engineers doing anything to correct the clearance issue?

HIM: No Sir

I was kind of suprised as to the whole engine mount thing, so I guess I'll put in some urethane ones before putting in the headers. Hope this helps.

Anyone else called them?

 

SLP are really morons sometimes. And they overprice everything.

 

Thats their standard answer for the past umpteen number of years. And there's not enough reason for them to update. How many people nowadays buy thirdgen headers? Only thru group purchases, it seems.

You may or may not have bad engine mounts, but the real fix is your steering shaft is crooked. You can loosen the shaft, slide it over a notch, and tighten it back up. No problems after that, and it doesnt affect the car or steering in any way.

Even with these minor details, I still feel SLP headers are the best smog-legal headers available for our cars.

 

I agree to that they are the best headers you can get that is smog legal, but I have really tight between my headers and plugs! Had to use the hammer to get the #8 plug in

 

I end up sending mine back this is after i tried takeing off the stearing shaft and also takeing the head off.Called summit and they exauged them for eldbrock with no problem.BTW bolted in with no real problems other than lack of space in the engine bay.Here's a tip though change your spark plugs while your stock manafolds are off and before you hook up your headers you'll save yourself some cussing till your next tune up.

 

BTW mine was a 92 purple rs maybe it's the color purple SPL don't like

 

I have a purple '92 RS w/ SLP headers, but I had a pro install them for me.

 

well so much for the purple idea

 

I have NO problems changing my plugs with SLP headers.........

 

must be nice i've had 2 different headers on 2 different camaros and had nothing but trouble trying to change plugs

 

Hooker 2055s make plug access hell.

 

Glad I have angle plug heads on the way

 

The 1 3/4 headers have some clearance problems. As for the steering shaft, i have urethane mounts and do not reccomend them. the engine sits higher then with rubber, since they are clamshell mounts there is no place for the engine to go if they break so i would get the stock ones, it also causes an interference problem with the mechanical fan setup if you have one.

My steering shaft fix was simple,

turn one of the flats on the shaft towards the header tube

find a piece of steel that fits tightly between the steering shaft and the header tube.

get a long pole.

place the pole up against the outbored side of the steering shaft at the same spot as the steel between the tube and shaft. you can angle the pole in from the drivers side hood hinge area.

hit it really hard with a big hammer.

you will put a very slight flat spot on the tube....... Just enough
