Powercore 4 on 08 YZ450?

[CRFsean]

Im thinking this is the exhaust(powercore 4) I am gonna buy as my local dealer (roseville yamaha) just kicked me back a 500 dollar gift card for the price that we payed as otdcycles.com had a price that was $800.00 cheaper. So does anyone have any experience with this pipe? I just want to ditch the stock one, but how about the white bros e2 or the XCR. The XCR looks very big tho.

I believe I have made up mind to go with the TI Dr. D Pipe. From what I have heard It's the best for the money. You have to agree Dr.D does know Yamaha's! It's also reasonably priced!

I'm telling you guys, try the Yoshimura RS-2, I was die hard Dr D for a long time, not anymore, now I am die hard yoshimura. Better quality build, doenst block the oil filter so I dont have to move the header, and the power increase is on par with Dr D but Dr D has no over rev. Yosh, all the way!

Thats interesting because the E2 has that prob too.

They are very long silencers, I wouldn't be surprised if the extra weight hanging off the back end is causing those weld brakes
