So lazy with the 6MT and 3.15 diff, lol

Ok - very cool...

"Was that a flame? Oh, yeah, well of course there's an exhaust pipe coming from the side skirt."

That 6-to-1 looks so good... tempting.

One would think you have enough headers by now

wow that sounds buttery smooth, almost more like an s38 than an s54. Always preferred the s38 exhaust note. I like it!

Haha, ya its ridiculous but so much fun. I'm trying to tame it down without losing its character though. And its splitting hairs but its actually a 6 - 2 - 1

Unfortunately it makes no torque lol. HTE couldn't get it to make any power up top but I have some graphs from similar setups make a ton of HP up top (Epic Tune) so I'm not sure what the problem was. The consensus seems to be the 2-1 merge kills the torque but makes the noise so I'm conflicted haha. I was thinking about making a second 2-1 merge that is either bigger or to carry it out longer.

I think this kit is for an E36 and I've made it work in the E46 chassis. I don't know how different it is from his E46 kit (or if there is a difference at all), but it would be hard to package in an E46. This one is going to require a custom A/C line (and I had to cut the metal partition).

I guess one of us needs to scan an s54 without headers installed with the shear plate...

Modeling equal length headers shouldn't be very tough and there are a few online suppliers that do custom mandrel bent tubing nowadays. Should be a lot easier now than it was back in the 2000s and 2010s.

What is a shear plate?

[Bry5on]

What is a shear plate?

That aluminum plate that ties the subframe to the frame rails. Which reminds me, I also want to design a flat sheet to close that M3 plate out and stiffen it up like the non-m plate

The only reason I initially S54 swapped my wagon was because I had a set of Kromer Kraft headers. They were old and tired but sounded amazing. They needed some repair and were pulled in favor of a "temporary" euro setup. I think that was 4yrs? ago, lol. My spring goal is to get them back on and I'm probably going to make a muffler to quiet everything down as I can't really buy anything I like at least that I can find.

Going from E36 to ZHP, I think there's room on the table to make more power and be similar sound level even if you are guessing at some parts of the design. IIRC we saw a ZHP left 15whp on the table vs a Stromung conversion muffler, Dinan or BMW Performance mufflers (E36 was even more than that).

Nice! are they still making those headers?

I think they've been out of production for 15+yrs

Oh wow. They really look like art.
