KWV2s still available?

Do these bolt right on? Or do you need to make modifications to the Y pipe?

I have a nameless axleback I'd be able to trade along with some extra cash. Or a whole borla catback.

Need one of these (scroll to the bottom), but they're discontinued. Will pay top dollar! (see attachment) https://www.btssm.com/?page=hardware

Are those Enkei M52s? I was wondering how the car looks with those! HAWT!

Probably got them replaced around 2012-2013, car is at 91,000mi. Had left/right replaced probably around 60 and 70 respectively. Right one was under recall.

Thanks! I actually did this experiment. The noise doesn't seem to change with parking brake. It also has a dead spot of maybe 5 degrees. I need to raise it around 10 degrees (or 2-3 inches) before parking brakes are applied sufficiently. How would this explain the engine load dependency though?

I have a strange noise that's best described as wheel bearing noise, but I have doubts it's the wheel bearings because it doesn't vary with suspension load (though it does with engine load). It's loudest at exactly 60mph, and makes the same pitch as the engine at 5th gear (but it happens in all gears). When it first comes on, it's pretty quiet, but gets louder over time. Here are a few symptoms (some that contradict each other) 1) When hot, brakes make the same noise (or make the existing noise louder --I dont know which it is) when applied. 2) When the noise just starts, it's entirely ENGINE load dependent (but not suspension load --when I upset the balance of the car, the noise does not change). No load, no/low noise. 3) When traveling at >60mph for an extended period, the noise begins to persist even though there's no engine load. I can shift to neutral, and the noise continues. 4) Rear brakes seem quite hot (I don't dare touch them) after an extended highway drive. Getting an IR thermometer soon to see if I can get an actual temp. The strange thing is, everything points towards rotors, but I had both rears machined, and it didn't eliminate the noise. However, if it's rotors, that doesn't explain the engine-load affecting the noise. My next best guess would be driveshaft or CV shaft. I got a shitty junkyard CV shaft as a replacement because I wanted OEM, and couldn't find it anywhere. Finally found a dealership who stocks them and will pay an arm and a leg for them if this is the real culprit. Anyone here experience something similar or have thoughts?

Did you notice a large decrease in damping on the low end with either of them (<1500rpm)? Or are they roughly the same? First thing I noticed when I put the WRX/Exedy in was decel chatter (faint, but still noticeable enough to be annoying to me). Engine also transmits a lot more vibration than stock (you probably need to drive one with the stock DMFW to tell the difference though)

I'm currently with an Exedy (not sure what model) and 06 WRX fly and to me it's a little harsh and makes the car sound boomy. I liked the smooth stock feel and sound and not crazy about racing the clutch or anything. I treat the car as more of a cruiser and dont need perfect rev-matching.

I did a huge amount of forum searching and haven't really found an answer to my problem. I know most folks (including my old mechanic) recommend a switch to SMFWs. I had my DMFW and clutch changed to an Exedy/06 WRX setup about 5-6 years ago. I immediately noticed a stark increase in NVH at lower RPMs (and the decel chatter), as well as a more metallic sound at low-load around 3000/4000RPMs, and it has bothered me since. It's time for me to do another clutch job, I'd like to either switch back to the DMFW or a quieter option. Just wondering if any of you have any thoughts on: 1) whether there is a quieter SMFW setup (ex: does 6 spring vs 4 spring make a difference?) 2) what options I have for a more reliable DMFW setup (or if OEM is the only way to go). 3) Car is now at Stage 2 and will be going for a conservative VF52 tune (maybe 260whp, stock fueling). Will the stock DMFW setup handle this? 4) Other options for preserving OEM smoothness/quietness

So the LWG map helped smoothen it out a smidge. Here are some graphs.... but it definitely still feels like the hesitation is still there. Without LWG With LWG It's certainly not a normal feeling by any measure. Also attached are the logs. If this is different from what the folks experience on this thread, maybe there's a better thread I can post this in in order to get more opinions. datalog47.csv datalog48.csv

I don't actually have access to AccessPortTuner. Do you think a low-wastegate map could be used to test this?
