there you go.

Was hard to be certain, as the original came out in... shards.

I actually am very jealous. It's one of those things I keep forgetting to buy...

Just got back from a failed attempt at data logging with Testo (seemingly didn't record anything), and it is decidedly quieter with that installed.



Action shot, reading your post.

Technically I think this is lighter than the original rubber sound deadening mat.

Hol' up, you added weight to the car?

Took advantage of my daughter moving from child seat to booster seat and did some hardcore modding today-- updated sound deadening pad under the back seat.

I'll be installing mine soon too. Looks great.

I wrapped my entire CSL intake in gold and I got laughed at.

Well well well lol.

You get laughed at regardless LOL

added some bling



… but did it such that it will not be visible when the airbox is installed in the car.

I pretty much have an f1, now.

Do you have a price in mind?

Emailed you.

[George Hill]

Yep, it is!

I was thinking M5board, but I don't particularly feel the need to list it at all if he's interested.

Doing a little spring project on the M3, which is fun-- with building the house, the e60 M5, etc, haven't really had time to do anything with it for a while. Changes:
1) new/updated/lighter/not crumbled under back seat sound deadening pad
2) Bry5on's additional exhaust mount point
3) Higher flow injectors (Bosch 0280156063), with new OE BMW injector o-rings and vacuum rail o-rings.
4) one step colder plugs (Denso ixu27)
5) creating a little spacer to allow my OEM (Die Wethje) CSL airbox from before CSL's existed to use the factory CSL air filter (my filter is slightly larger in one corner, so it doesn't get a good seal as is with a factory filter)
6) replacing two of the power steering lines that are slightly weeping
7) installing a wideband so I can use the forum partial throttle auto tuner
8) moving to an HTE tune, to update for my new injectors and colder plugs, as well as tuning the WOT with the wideband/data logger.

All my recent car projects have been e60 and e82. The e46 is so nice and easy in comparison. Really missed it.

Saw this in another thread when checking head studs vs. bolts and was wondering if your S54 had a head gasket failure:

I’ve replaced my head bolts one time in almost 20 years of e46 M3 ownership. It’s unlikely I’ll live long enough to have the reusable arp head bolts be cheaper, at 4X the cost.

Nice. Have you seen the equal length stepped headers for the E60 M5 from Euro Power Sports? He has a video up with stock exhaust and those headers and it sounds just amazing and right.

The evolve long tube headers (made by supersprint) that I have installed are already pretty absurd looking/sounding/power gaining.
