That setup in the video is really close! Mine was nothing near that bad.

If there are clearance issues with the collectors, and they are solvable with cut and weld that's what I'll do.

Please keep us posted on what you find.

That's clearly not right, looks like it's literally touching the under body. I recently swapped out my Spohn solid mounts for UMI solids/stock pedestals in preparation for a new header set up with flanges. I took a ton of pictures and wanted to start a thread showing the difference in height between the two, maybe I'll just post them in here. My point is though that even with the engine jacked up with Spohn mount the collector/flange wasn't touching the under body. A part of the y-pipe was however which was probably due to the exhaust being built before I installed the Spohn's.

From your signature it looks like you have ARH's now, how did they fit?

Yes sir, I do now. The ARH fit perfect! Just for the sake of checking I tried them with the old rubber engine mounts, new rubbers and the polys. Not a problem with any of them. Y pipe doesn’t touch anything. The problem obviously wasn’t my car or the mounts I chose to use!
Good 3/8" clearance with the ARH. This is where the TSP stuff gave me problems.

ORY tucks up awesome.

Little hard to give an accurate idea of gap but its right at like 3/8" maybe a tad over.

Very nice. So glad I didn't end up pulling the trigger on the TSP's during the Black Friday sale. Looks like I'll be saving for some ARH's.

I know some folks have had good luck, though. Thats why I was pretty upset that I ran into the problems I did. I tried 2 sets of their 1-3/4 headers and Y pipe too!!! In the end after how long my car was in pieces and how many times I had to send headers back and forth I am not the slightest bit upset at what the ARH system cost me. Buy once cry once!

Here’s another example of the collector being very close to the floor board. This one is a tsp

I've got good clearance with TSP 1 3/4 headers but I'm also still using stock 100K motor mounts.

Also running TSPs 1 3/4, with plenty of room to run 4” cats. The cats are Pacesetters, also running Speed Engineering True dual kit out the back. Here’s a small pic after LT install.

I bet something about the car is off. I know that I bought a seat mount for my Miata and it was off by 1/4 inch . The company is reputable and the product fits most cars but for some reason mine was off. Probably built on Friday afternoon.

Everything fit neatly, no issues with the k-members, ls1 external knock sensors on the LS3 cleared easily, and plenty of space between the collector and floor board. Both the driver's side and passenger headers went in with minimal effort, with the car lifted off the ground 24". I did not remove the steering shaft, oil filter, or loosen the engine mounts. I actually had each header in and out four times while I test fit things.

Those are TSP's? What are you doing for the ball ends?

Yes those are TSP's. Shortening the collectors, and using two bolt flanges to mount the cats.

I test fit them with the flanges tacked on, everything looked good so they are now welded up. I got them ceramic coated also
