This past weekend some idiot took out the internals of his Supertrapp on a big Kawasaki KLR dual sport dirt bike. It was riduculously loud. You couldn't carry on a conversation when he drove by. Idiot.

 

A Cobra on any thumper is way too loud

 

I used th think my buddies 350x with a worn out Cobra was the loudest. Now it is just the most irratating. My CT440 with a Curtis Sparks is louder but it is a symphony of thumposity. Pure music to thine ears. However, on Sunday, at Red Bud some guy had a TC480 with the TC prepped Supertrapp 4" Shorty and honest to god it was louder than a Harley with Porker pipes. I want it! When you see me at Silver Lake though, I'm in stealth mode with the Pro-Circuit T4 spark arrestor. Just a tree-hugger down deep I guess.

 

The loudest pipe i ever heard was on a husqvarna. it was a 79 with no silencer and bored 80 over. besides that its an indy car from like 5 ft away.

 

I disagree cobra pipes on any thumper is to loud I hafd a yfm 225 with a cobra header/exhaust nad it was throuty but not loud. the loudest pipe I have ever heard would be a tie between my 85 rm80 with no silencer and a big gun on a 440ex we where riding on 2000 acres and when we where about a mile away U could still hear it it was crazy. my FMF gold series/power core 2 combo on my 250r is pretty loud to. and when my end came of my DG silencer when I had fmy stock pipe on was LOUD to.

 

the ds650 was my buddies, and he has the ron woods
stage 1 kit on , the pipe is a rotax pipe. he was
the only one there with a pipe on the ds650.

 

the loudest pipe for a four stroke is the [red]RCM[/red]. if you don't belive me buy one and you will see. just my 2 cents.

 

wb e-series on a 300ex i was standing in the portable(portable class room its the size of a class romm except up on bricks and it can be moved like a mobile home) at school and this guy started up his 300ex and the portable started shaking he was about 25 ft away. then he reved it and stuff started rattling on the shelves!

 

the loudest i a have herd was a DG pipe on a 98 warrior it was loud, louder than my FMF MM2 on my 250x
