Pro circuit or graydon proline

[9300EX]

OK I think I have it narrowed down to either a pro circuit T4 or a Graydon proline disk type exhaust .Any prefence from you guys? The T4 puts out more power cost less and is lighter then the graydon ( 400EX pipe shootout) but there is something about the looks of the Graydon I like.

GRAYDONS ARE LOUD!!!

400EXjoe How do you like that IDS2? I had one on my 300ex but the thing rattled like crazy. :cool:

I LIKE IT ALOT. I HAVEN'T RIDEN ANY OTHER PIPED 400EX'S SO I HAVE NOTHING TO COMPARE IT TO. IT SOUNDS GREAT AND GIVES A GOOD INCREASE IN TORQUE. ITS ALSO CHEAP. $179.99 FROM ROCKY MTN. I RECOMEND IT BUT SEE WHAT OTHER PEOPLE HAVE TO SAY. ALSO, DON'T WASTE YOUR MONEY ON A FULL SYSTEM UNLESS YOU HAVE ENGINE WORK DONE ALREADY.

I would get the T-4, I have one on my 250ex and it's makes a HUGE difference by it self!!

A guy we ride with has the Full Pro Circuit on his 400ex with a K&N Power Up Kit. He said it made it feel like a different quad. He said it was awesome. I like how it looks on his. It sounds great too. You can`t go wrong with the Pro Circuit.

I still throw in a vote for Curtis Sparks.

I knew somebody would say to get a Sparks. It`s an awesome pipe. That`s the pipe I would get if you didn`t get either one of these.
