Offline project dc2



800$ shipped within 48 states for our 1 3/4 Standard stamped collector longtube headers ( L-based engines)
850$ shipped for our  1 7/8 stamped collector longtubes

950$ for our  1 3/4 Premium merge collector longtube headers ( LS-based engines of course)
1000$ shipped for our 1 7/8 premium merge collector long tube


1200 shipped for 1 7/8 STAINLESS premium merge collector longtube header 


 keep in mind. merge collector headers are for maximum power however due to their slip fit collector  style they do leak a minimal amount and its inevitable without going with a double slip collector.   90% of merge collector headers on the market exhibit the same issue  . the only ones that dont  arent a true merge collector instead they used a formed outer with a bent and welded inner spike.

What is the difference between the stamped and merged?  In the pict it looks like all 4 tubes have the corner edges lopped off by the collector is that a restriction at all?  What power levels do you reccomend with these before going to 1 7/8"?  Thanks

stamped and merged is different in the collector portion.   its not a restriction but not as efficient as merge collectors where the pipes scavange off one another and vaccum helps pull the exhaust gas out. Theres a lot of debate on the whole 1 7/8 and 1 3/4 deal  it all really depends on how your setup is, what cams, how big the motor, what you intend on doing with the car etc.

Really impressed with how well the 1.75" fit in your rx7 with samberg stuff.  From older posts it looked like it was going to be hard to get them in and we would need a BFH.  They went in really easy from the bottom with two people and had good clearance pretty much everywhere.  The car had to be jacked up pretty high, though.  They also look great.

Clearance shots below

You'll notice that the driver's side is a bit lower, but it's fine. A 3" exhaust made for an FD will sit lower.
I had no issues with installation, nor fitment.
No BFH necessary. I did dent one area of the heat shielding in the transmission tunnel only for more clearance, not because it was touching.

Overall, very satisfied.
