The stock 3.62 is great. I just upgraded the diff but kept it 3.62– zero regrets.

What’d you do to your diff?

Wavetrac

I read some good things about Wavetrac . How you like it ? I have 170k on mine and definitely need to rebuild it.

Haven’t had the car on track with it. On the street, feels identical.

It’s silent, which is nice.

loved:
- 996 BBK upgrade - totally changed the aesthetics of the car overnight. stopping power is better, but not otherworldly. the visual update was worth it alone though, esp the 2-piece floating rotor upgrade i did
- powdercoating my BBS RGRs gloss black, another aesthetic mod that really made me happy
- exhaust work - i have RE El Diablo, Status Gruppe Section 1, Megan Catless Headers (ceramic coated) and my car sounds amazing. my favorite out the hooptie fleet
- ground control front & rear sway bars and adjustable endlinks - these changed the way the car handles overnight in the canyons, love em!
- KWV3 coilovers - best handling set up ive ever owned

HATED:
- Avin Avant 4 - total headache and poor support from Avin. i bought all the options too...quick way to waste $800
- Catless headers (without thinking it through). at first, it was WAYYYY too loud with my El Diablo section 3. then i did a second resonator to kill the rasp, it was better. the catless smell over time killed the vibe so i recently bought some high-flow cats for my section 1. never go full catless unless its truly a dedicated track car...otherwise its just not worth it. lesson learned.
- Vorsteiner full carbon fiber hood. this was installed by the previous owner but the UV finish installed by Vorsteiner is horrendous. its peeling and cracking on all the unpainted parts. seems really low quality (and its authentic)
- Vorsteiner full carbon fiber rear difussor - again, installed by the previous owner, but this thing has never fit right and always pops out of place. annoying.

What cats did you end up going with? Im trying to get rid of the catless smell as well.

Probably. My exhaust is not too much louder than stock (modified my stock muffler, think SS sport volume) and I'm extremely pleased with my airbox. It's plenty loud for me and makes a much better noise than what I've managed to get out of the exhaust.

A good condition stock muffler popped up for free a couple months ago on craigslist and I really regret not picking it up. I really want to try the quiet exhaust, loud intake setup.

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

[Obioban]

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.

[eXpensiveGears]

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

Nope.

Muffler volume seems to be directly proportional to muffler weight.

[Tbonem3]

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.

Is the OE CSL muffler lighter?

[Thoglan]

Is the OE CSL muffler lighter?

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