Ok, I'm just trying out something I've read a few times...

Can you post up and let me know if you have the 1 - 3/4 or 1 - 5/8 headers, and if you had to dent the header for the steering shaft or not? Thanks.

 

1 5/8". No dent, plenty of clearance. Y-pipe didnt fit.

 

I have the 1 3/4" and yes i had to dent them.....Eric

 

1 3/4 w/o air, coated, no dent. Just had to replace the driverside motor mount to get clearance between header and steering shaft.

 

I have the 1 3/4. No denting, no new mounts, nothing needed. Fit just fine. Have had them in and out many times now with no problems.

1 5/8 slp w/kit purchased in 2001 here at TGO during a group purchase. No problem with installation. Y pipe fit. Passenger side went in much easier than the driver side. When I finally an engine swap on the 92RS, I will go with the torq style bolt.

 

SLP 1 3/4 headers and did need the hammer to dimple them on the driver's side.

 

Have both 1-5/8 and 1-3/4 slp headers. Have had no problems with either. When there is a clearance problem. I "think" it maybe a engine mount issue . When installing new mounts make sure you have the left/right side mounts in the right location or it will move the engine over towards the driverside of the car and create a clearance problem with the headers.

 

1-3/4, with no problems.

 

1 3/4 No denting. Y pipe perfect. Had "slight" rubbing issue on steering shaft. Took file and filed away 1/16 all round the shaft. No problems now.

 

some cars have that problem,my best freinds car in 93 had to make adjustments to his car for the headers to fit loosened up the steering column at the floor inside and slid it as far over as it would go(91 z28)..my car they slid right in,changin plugs well homemade tools fit the job..btw we only use 1-3/4 slps

 

for previous post of mine..i also use hooker/headman 1-5/8x3".the slp 1-3/4 and the heddman/hooker 1-5/8 are a proven set of headers they work!

 

slp 1-5/8" headers.
Small ding to clear steering.

1-3/4" no denting, new poly motor mounts.

 

Had 1 3/4" SLPs (now have Hooker 2210 LTs). Stock tired mounts, no denting. Had to loosen column bolts and shove it over a bit though. I ended up with at least 1/2" of clearance when it was all said and done.

 

I've got the 1-3/4", with a mild dent. I'd try to move the steering column if I had it to do over, though...

Oh, and the Y-pipe fits well.

 

1.75" with new poly motor mounts..dented to clear.Y pipe was another issue with a deep pan..

 

I've got 1 3/4" SLPs without AIR tubes that I got Jet Hot coated. I've also got energy suspension motor mounts and I have plenty of clearance between the steering shaft and the headers. The shaft used to hit the headers because a previous owner of the car had moved the steering column to the left (which scooted the steering shaft to the right) but now that I have the steering column centered where it's supposed to be everything is perfect. The y-pipe also fit great!

coated dual cat slp 1 3/4 headers.

dent indeed

 

i havethe 1-3/4" headers, w/o AIR.

the steering shaft did hit, so i grinded a little of the shaft away to clear it. i couldnt bring myself to dent the header, especially since i paid $220 to get them coated.

everyone gives me crap about grinding the steering shaft, but its been fine for a while. i keep an eye on it for stress cracks, etc.

keep in mind that i have original motor mounts too, so mu engine is a little lower than it probably could be.

I installed the SLP TRI-Y 1 5/8" headers with no problem. Allen

 

I have the SLP 1 3/4 on L98 Alum heads.
and they just touched, so I removed the steering shaft and
machined the shaft down just a little , mainly takeing the corners
off.
Better than denting those Expensive SS SLP Headers.

 

1 3/4 SLPs and I had to squeeze (in a bench vise) one DS tube to clear the steering shaft, also the DS Y crossover pipe to keep it a bit further away from the oil pan.

 

1-5/8, with air tubes, original motor mounts, they fit fine.

 

I know this may sound stupid but on my car my brake lines are right against the steering shaft between the shaft and the motor. I checked out mdformula350s engine bay pics and his are between the shaft and the body. Is this normal? If I go messing around with the steering shaft do I need to worry about the airbag going off? I have the same headers as md's bought in the same group purchase and a 90 gta.

 

well i can answer this

i bent the brake lines to the other side to make more room. simple as that.

the 1 5/8 would fit fine on my car, the tri's either side would fit fine.

it seems the 1 3/4 newer ones give some people problems.

no biggie just a dent and i wasnt going to touch the shaft especially after putting heavier and bigger front rims and tires.

 

1 3/4" no air... no denting... but it hits the pass frame in motor compartment... wasted the engine mounts

 

I have the 1.75 they rub the shaft with the afr heads but not with the trick flows I had.

 

On my 1-5/8" SLP headers mixed with Dart Iron Eagle heads (straigt plug hole), there is almost no spark plug clearance at all for #8. On my GM heads there was no issue. I have to use the shorty header plugs from Accel to get 1/8" clearance from the plug boot. With standard length plugs there isn't much room to breathe without the plug wires! I think #5 is pretty close too.

The really funny part is that my y-pipe didn't bolt back up with the new heads, the headers were a good half inch further apart at the 'collector'.

Anyone else have this issue with their header/head combo?

 

1-5/8, with air tubes, original motor mounts, they fit fine.

 

Got the 1 3/4 slp coated with air they hit slightly replaced mounts with es polly ones still hit so i pulled out the hammer.

 

1 3/4" No dent, but did replace the motor mounts with energy suspension polyurathane mounts. Here is what it looks like.

 

Kerry, on Joey's ramjet car, we had problems with the steering shaft hitting the header. We went as far as to move the steering column a bit in the factory-ovalized mounting holes. This effort was of little help. To fix, simply turn the wheel a couple times Back when I had SLPs, the steering shaft was a good 1/2" away from the tube.

 

1 3/4", no dent, but removed steering shaft first.

 

I had just installed the 1 3/4" SLP headers in a few weeks
ago. I used the Prothane poly. motor mounts and I have a
good 1/2" clearance from the steering shaft. I had to do
nothing to the headers to make it fit and clear. Only problem
was to reroute the brake lines so the brake fluid doesn't boil
over on a 1/4 mile pass. Just a precaution. They weren't hitting
the headers, but I don't feel like taking a chance on having
my brakes crap out on me and get injured/killed from my
stupidity!

P.S. I am using a Ramjet 350 crate motor that comes
with GM Vortec heads.
