hey i just got a 2003 400ex and was wondering if the fmf factory 4 pipe was good or not, also the yoshy full pipe, or even pro cuircut and white bros. what are your opinoins on these and these companies. My price range is about 400.00----thanks

 

i was in your situation not to long ago. id go with a yoshi rs3 full system ive found them for about 360 for a full system and a few people i know run them and said they wouldnt trade the rs3 for anyother pipe. another good pipe to look at would be a curtis sparks full system but i think there about 460 or 520 on the sparks website but if you saved up they'd be something worth looking at. i have a friend who runs one on his 02 thats got a hi comp piston and cam and he passed my step dads banshee on alot of occasions ( my stepdads banshee is stock tho) so id say yoshimura or sparks if you could save money for the sparks go for that.

 

hmf makes a good pipe for them too. i love my yosh TRC

 

What abut the LRD full system with Ballistec coating, that looks nice and it will never rust .But idk about power gains.

 

I have a 416 EX with the Sparks X-6 and it performs and sounds great.If you look around on ebay you can find them cheaper,I bought this one for $489.00 shipped.I put it and a rev box first with jetting and it made a big difference.jmo
