5 Mods you loved / 5 Mods you didn't

Which brand on those so we know to avoid LOL!

That makes sense if it's a track car but damn still after ten minutes hahaa.

All those parts are a waste of money no matter how cheap they appear to be at first glance whereas quality parts at 5x the cost are not, to me at least.

Noise from the bearings?

I lol'd at seibon, were they ever supposed to be any good? All these pseudo cf companies make me smh, everything is always a compromise. Buy it right and buy it once.

My buddy has a seibon hood and trunk I think on his e60 m5 and that shit is straight trash. Unfortunately none of my taste has rubbed off on him.

Yeah the sphericals were making noise/were loose with some play after 1 track event… and I could feel the loose/play while driving…

I bought the Seibon CSL trunk used for like 400$ and it was for a dedicated track car. I installed it and 10 minutes after I removed it from the car cause fitment was crap… and it was a dedicated track car LOL, can’t understand people with cheap replica parts on their street/show car…

I had 12x E46 M3 over the last 15 years, some were track/race cars and some were street cars. Here are my 5 best and worst:

-lightweight flywheel
-spherical bearings rear upper & lower control arms
-TTFS CSL tune
-Hard Motorsport composite sunroof panel
-Seibon CSL trunk

Best so far, 3M Crystalline 70 all around. Stock locking and a huge difference in heat rejection. Maybe it's only my car but heat inside is much higher than all other cars I've had.

I would love a CSL sect 2 & 3, but can't pay so much for such a small upgrade.

[Cubieman]

From what ECS has to say the entire CSL exhaust system reduced weight by a total of 11lb, the muffler accounts for 5lbs of the reduced weight.
I think they used different materials as well as thinner walled pipes, if that is the case (thinner pipes) the people that like a bit of S54 rasp would love the CSL exhaust.
Going from euro headers/section 1>SS stuff definitely reduced the rasp and I would have to assume it's partly or mainly due to resonance from a thicker walled pipe, at least that's my take.

[Thoglan]

Is the OE CSL muffler lighter?

Yes but only by a few lbs. And reasonably louder with a bit of a different tone.

[Will]

Are there any options to keep the exhaust sound stock or less than stock but cut the weight? The muffler is relatively heavy.

If you go 2.5" headers back, your overall volume, and pitch, seems to drop. So if you have a full 2.5" system, I wouldn't be as worried about noise from an aftermarket muffler as a bone stock car believe it or not.

Nope.

Muffler volume seems to be directly proportional to muffler weight.

It's just the best. Make the part of the car that sounds good loud, make the part of the car that sounds bad quiet, in the process enjoy no drone or obnoxious loudness when you're not driving the car hard.

[fattycharged]

Update: Installed a stock muffler a couple months back and loving it. Highly recommend the quiet exhaust, loud intake setup.

Best thing I ever did
