The powercore is garbage IMO so you're not missing much. I ran one on my 70 with a TB 88 with race head and it just sounded like crap. It was real raspy sounding. I hated it, which is weird because my friend has a powercore on his 50 and I dig the sound. I just bought a used two brothers big bore pipe and I love it. Much nicer sound. FMF is doing 20% off their exhausts now, I'll bet the factory 4.1 is a pretty nice pipe and you can get it for 239 new. Lots of people run the 4.1 on thier 50s. I was about to bite the bullet and get one but I got lucky and found my pipe used. It sucks though cause finding a used 70 pipe is pretty tough so unless you're patient you'll probably have to wait a while before you find one.

Exactly my scenario. I'm sponsored by FMF for racing nationals and get my pipes for my CRF302 at an unbeatable price, bit my discount doesn't carry over to anything else. As much as I wanted the Factory 4.1 to match my big bike I just couldn't justify the price for a new one. I too found a used two brothers big bore pipe and absolutely love it. It has a hell of a bark to it and breathes great, and the quiet insert still sounds good and does it's job when I'm riding in town on streets. (cops don't care, and everybody waves).



If buying new I would do the FMF, then BBR, then 2Bros in that order. All three top notch and sound and look great.



If you PM me a cell number I can text you a video of me launching in the snow with quiet insert in with my GPX 140 motor. I'll have another video with it out after this weekend

 

Theres a guy selling a yoshi 70 pipe in the classfieds you may be able to get on that.

 

Check out Stickyickys thread he has the used 70 Yoshi for sale. If you go the new route I'd say look at BBRs D2 or CHPs UHF both are quality systems.

 

Yeah i've been trying to get a hold of him. I told him I would buy it if he showed me some pics and it's been a week or so and no pics. What do you all think about the pro circuit t-4? I saw one new on ebay for pretty cheap.
