No dust on my OEM belt and pullies on a 97.

I had underdrive pulleys many years ago. No belt slippage or dust. Just charging issues.

I had slip on wife's G35 with the gator belt. I would dump that gator belt.

Get a Continental or O'Reilly brand.

Also get a overdrive alternator pulley (49mm/2") to keep the alt spinning oem speed. You will need to measure the belt length needed.

Honestly, I don't think any of them are "worth it".

i dont think i would spend money to swap under drive pulleys for the whole 2-3 hp they net you.

Id clean it all up, put a new belt on and check the tensioner while you're at it

The gains from a UDP set show more around the 6k+ rpm range. They extend the hp band.

This is where many dynos/tuners start to pull back because they think the show is over.

I personally like them. I haven't gotten a PS pulley yet but I plan to. I don't have any issues with charging or anything also. It's been recommended to use the 1 piece dampeners. If you stay under 7k either the March or steeda is fine
