The sound is exactly what I've been looking for. Has a very tight raspy sound but keep in
mind I have a catless downpipe so I'm sure that gave it a bit more uph.

Here's a few iphone sound clips.





Here's a crappy take off clip


Hey man,

I know you got rid of these but do you know what the "coughing" sound is when the revs come down on your video? Did it have something to do with the valves or your castles DP?

Thanks!

I must be the downpipes; however without the downpipes it did have those coughing sounds every once in awhile.

I like to call the exhaust farts
