How loud is the curtis sparks pipe with a jet kit and air filter on a 400EX? How many decibles? because ive heard that they are really loud
i got 105 decibals at the local track.
01 400ex 416, xr cam, Sparks x-6 exhaust, Houser chrome stem, burgard a-arms, douglas shamrocks beads, razors, ohlins shocks.
is there a diff in sound and power between the x-4 and x-6 also are those pipes good for 400EX's with no engine mods?
The x-4 is good for a mostly stock engine, the x-6 is for heavily modified engines.
If you put an X-6 on a non heavily modified engine will it hurt the stock engine?
I'm not shure, you might want to check with Sparks on that one.
