I don't know why this word didn't come across my mind sooner.

I will get some pics tomorrow after work and put it on here.

That is one way to end it

I like to use the KISS method whenever possible, but I'm always torn between my tunes and the awesome sound of my engine and exhaust!

For me it is 98% exhaust. If I had 2 badass leafblowers like you it would b 100%

I installed FI test pipes and exhaust. Don't have the vibration problem, but the HISS is driving me crazy.

I love the power gains way too much to give it up

There shouldn't be any vibration. Something is touching the exhaust. You may need to put a few washers on the exhaust hangers to space it down.

I thought you were going "washer mod" here for a sec...

OhOhOh123456 here is the video o me taking the bottom portion off and what I did to get rid of the buzz.

Sorry for the crappy lighting.

Hotrodz · 02-25-2014, 09:36 PM

Very Nice... +1

I use dynamat like products for large surfaces, but the utility of it diminishes with the surface area. For my hatch, I used felt tape where plastic panels met other plastic panels or touched metal. Zero rattles, cheap, and much easier to apply than dynamat.

This is simply fantastic. I really didn't expect such a detailed video. I will definitely try it out. Thank you very very very much.

Could it be an exhaust leak or maybe your exhaust pipe is rubbing up against the under carriage?

I don't think so. I think it sounded more like buzzing and always came in under the drone rpm (1.7/8k-3.0/5k) range.
