The tips are replacements, I also replaced the exhaust with Agency Power cans (which really sound nice) and got the tips from eBay.

Plans: Pinion bearing in transmission is making noise, so "while I'm in there" to remove the transmission to send to be rebuilt, I plan to replace the clutch, TOB, RMS, IMS, AOS, chain tensioners myself.
Leading evidence: 'Replace exhaust' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace clutch, tob, rms, ims, aos, chain tensioners myself' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Clutch actuation changes the sound slightly, as does the current gear selection, since those things change the load on the pinion bearing.

I've had thoughts of instead of putting more money into this car, of selling (with full disclosure of all known issues) to buy a high mileage 996 turbo, as it seems they could be a better long-term platform, prices seem low-ish, and I can still get decent money out of this one while it is still running, versus after something serious with the engine occurs and it turns into a roller.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Made it! Happened as I pulled into my driveway by chance.
1999 C4 Ocean Blue 6MT
Bought for $14,000 July 2018 with carfax showing no accidents and not much else records-wise.
Original IMS and no record or indication of major engine work.
Daily driver, runs like a champ.

I hope it's worth it. I've had thoughts of instead of putting more money into this car, of selling (with full disclosure of all known issues) to buy a high mileage 996 turbo, as it seems they could be a better long-term platform, prices seem low-ish, and I can still get decent money out of this one while it is still running, versus after something serious with the engine occurs and it turns into a roller.
Love threads like this that show how durable these cars can be instead of scaring everyone like the current Coronavirus mentality. Just about to hit 102K on my 99 C2.
I think that the ocean blue metallic was a popular color that year, mine is the same color same year 99 build date 3/98. I do have you on miles still, 205k miles and still runs great.
you won’t regret moving to a turbo. I already have just over a year ago now. It’s a blast having that much more power.
you just need to learn when to use it.
205k miles, nice!
It's a great color, lots of dimensions depending on lighting. I spent quite a few hours with a clay bar, compound and polish bringing it back, totally worth it. The front end is full of chips which given the dark color are quite visible. I've thought about painting the front clip but then I'd probably stress about driving it more.
The turbo would be nice to make up for the hp I lose at 5400' altitude on the NA car. We'll see how the next few months play out.
Posted in another thread but 203k on mine and just did a spireted DE day on mine. Its fun pulling to 7200rpm in 4th at over 120mph before slaming the brakes into a right hander.
Pit shot
GarrettSR5,
The pinion sounds like a fairly low level "rushing", "roaring" or almost like a semi-periodic wind noise but happens at all road speeds, and varies with road speed. Seems to come from the transmission tunnel and also seems to be transmitted through the shift cables to some degree. Independent of engine speed (rpm) or if the clutch is in or out. Clutch actuation changes the sound slightly, as does the current gear selection, since those things change the load on the pinion bearing. I think I've heard that 4th gear places the highest load on the bearing for some reason, and it does seem louder but it's hard to tell. Also in full load or full engine braking is surprisingly quieter (for me at least), feathering the throttle in gear, clutch engaged, so that the load through the drivetrain is close to neutral stress (coasting) seems to make the most sound.
Hope that helps, it's hard to describe in words.
