No clue, I am happy with grinding it down but some people might notbe, cause I guess it could hurt the strength of it.

Ls1 steering shaft allows room for headers apparently. I'm doing that upgrade because my rag joint is shot

Any updates on whether or not these work with a Pacesetter Y-pipe? I'm considering buying a set of these. I apologize if this has already been answered

Just saw these posts sorry.. Yes, I believe the PaceSetter Y-Pipe will work. For the annoying Y-Pipe issue the F-Bodies have, Mufflex also makes a kit that works to solve that issue. I am assuming it works for LT1's as well. Here is a link:

Just a update, these things are doing great!!! They have turned some pretty colors, took the car on a 12 hour day trip to the beach and no issues. These headers sound absolutely phenomenal with SLP LM1.

Damn wish they made something like this back when i still had my lt1. I just put some of their headers on my ls1 t/a though. Besides a terrible rub on my steering shaft even after taking a hammer to it ( new motor mounts would probably give a lot better clearance) and the y pipe clamp and bang issues, i love them. They sound so great with my hacked up stock exhaust (not sure what muffler was welded in but its got sound).

Are your headers D shaped at the flange or a true 1 3/4 or 1 7/8 round diameter?

Will you ever offer a 2" for LS/LT?

Speed Engineering

iTrader: (35)

Nope, they are regular oval port matched flanges with 1 3/4" primaries. We offer an 1 7/8" in the LS headers, but no plans as of yet for 1 7/8" in the LT1's.

Why did they go from $430 to $800?

Yes, sorry our Y-Pipes are on back order at the moment. We are in the middle of revising the design a bit. We should have a small batch next week, but our next full batch will probably be 3-4 months out.

Thanks

Any possibility of building a set of LT's that will fit the 93 Z28 with the air injection fittings correctly positioned? ie: the passenger side threaded riser tube welded in the rear tube #8 rather than the front tube #2? The driver side position is the same so it needs no change.
Thank you

We dont unfortunately. I believe Pacesetter offers an air/egr version, but not sure which primary they sit on.

Thanks

Have these headers been redone for fitment? They are good looking headers at a good price, but the OBX headers are not too much more and they are stepped headers from 1 3/4 to 1 7/8", and have 3.5" collectors. Even with that size collector, they need no hammering to make them fit correctly underneath the car, and they require no hammering whatsoever on the area near the steering knuckle. I have installed 3 different sets so far, and the only thing needed is the take the bolt out of the driver side motor mount to tilt the engine, and remove the starter to put on the passenger header. I haven't installed a set yet that rubbed anywhere. The driver side header will require you to run a shorter style oil filter, not the long ones. They are a great header, and I prefer them over a pacesetter or a hooker, seeing that I have ran all 3 brands.
