theres alot of debate on actual numbers and gains. but every little bit helps when it comes to flow. i have already dropped to a 2.5 pulley with supporting mods. i plan on P&P the TB and Blower when i do 1.9 rockers and get it tuned. real question is. do the m62's have silencing slots like the m90? and could i fill them in if i want to? i know filling them in on the m90 makes it louder. would i get the same thing from the m62?

I'm pretty sure the M62s have the silencing vents just like the M90. Speaking from 1st hand experience, I wouldn't bother filling the vents. I honestly don't think I noticed any difference filled vs not filled and I was unfortunate enough to have some of a filling let go and go through the motor - not cool.

The sliencing ports on the m62 are a little rounder and not as long as on the m90. The problem with filling them on the m62 is the material is not as thick where the ports are(as it is on the m90), making it extremely difficult to fill it safely with anything short of TIG welding it. TIG welding has its own problems with warping of the rotor casing as well. For the m62, its really not worth it IMO, the thing screams as it is with the 2.5 pulley and a good intake.
