Thank you, thank you, I am here all week!

Blocking the resonator only has an effect on start up is my understanding as its supposed to balance off the richer mixture sounds at start up to warm the cats. I do not believe it has any effect once tha start up period is complete.

Bingo! God forbid you get caught drilling holes in your airbox. You must spend ridiculous amounts on an aftermarket HAI that does the same thing!

Best advice so far

More air in does nothing unless you can get more air out at the same time...

^^^^^ i was gonna tell him to drill holes in his mufflers......if he didn't like it he could always epoxy lag bolts into the muffler or just go all out and put baseball cards in his spokes

As crude as the test was, there's at least some data to prove that the "hot" air intake has some benefits. https://rennlist.com/forums/997-foru...surements.html

Let's see some data to prove otherwise.

Hey more power to ya if you think it adds 3-4 HP's. I personally think that 1) if it adds any more power its negligible at best and not noticable at all contrary to people's placebo butt dynos (and there are plenty who think it reduces power) and 2) there are plenty of better ways to add real sound to the car

Also I just think it's funny that people were aghast ne horrified, that someone would consider drilling their airbox even though it's quite common with the air-cooled crowd and it's really the same concept as adding a much more expensive aftermarket HAI

To clarify, my statement along with the rest of my post was in SUPPORT of swiss-cheesing and in opposition to those who were criticizing the idea.

I think I'll have cheese and crackers for lunch.

There's a bunch of stuff in Bimmer forums about drilling holes in your mufflers for more sound.
Of course....that would be stupid.

I'm always amazed at forum members command of the English language and ability to both support and diss a post! There are responses related to increase/decrease in hp. Let's remember his request for input was only related to sound.
My recommendation to increase sound is push sport and pse button. Take a 110 lb woman for a ride. A high rpm ride. Then use your porsche approved drill bit with wing in up position for 4 hr (see wing posting) to elicit lots of increased sound.
Lots better than passing car at night on my k100rs with wife on back. Drop 2-3 gears. Immediately after passing dump throttle. Huge backfire and shoot a 3 ft flame from tailpipe. Scare hell out of car. Wife quit riding with me.
I say drill away!
God forgive me for having 2 scotches and a Cuban cigar.

Not correct! Listen to the video again. It's my car. It makes a big difference above 5000 rpm. It's the high pitch noise you hear. More pronounced if you fast forward to ca 50 seconds. A little bit like opening a hatch to the engine bay. Or the YPVS valve on a Yamaha RD350 for those of you who know Warm engine or not - intake sound is always there. The video is shot after 25 minutes of driving to work.

Of cause resonator has no effect except better intake noise.

RD350? Great sound and bike. Not near as loud as a Hodaka rat or Kawasaki 500 triple 2 stroke with expansion chambers whose packing lasts about 1 1/2 hrs. All 3 cool bikes.
Sadly the original Kawasaki had drum brakes that took forever to stop from high speeds. The only vehicle that caused me to throw out both underwear and pants when I left Blueridge Pkwy at triple digits and tried to stop in Clingmans Dome parking lot before running out of pavement. Sadly when they put disc brake on it they detuned it. Finally stopped but didn't go like before.

Wanna talk about nice sound on a bike?

KTM RC8R - Full Ti- Akprapovic Evo 4, full club race kit w/o dB killer or Ducati 1098s with full Termignoni's... those sound awesome!
