I have a "00" 300EX. And over the winter I am interested in upgrading some of the stock parts on the quad to improve performance. Exhaust is one of them. There are so many choices out there that I was wondering who has had what luck with which one's. That was a mouth full. I am leaning toward White Brother's E-series and FMF powercore IV. Does anyone have any experiance with either of these or any other pipes?
How loud? What kind of gains? Long lasting?
Thanks for the help.

My friend has a '97 300EX and he just got a Cobra Megaphone for it. It helped the power all around. It is also alot less than an E-Series or a FMF.

'88 Quadsport 230 '99 CR80

 

The most powerfull, loudest etc. is the FMF Megamax II.

If you're planning on leaving the engine relatively stock, you might want to look into the Supertrapp system and the Powroll System. These two were the best in a pipe shootout that Dirt Wheels did a few years ago, with the Powroll system slightly edging out the Supertrapp. I think they both gave you about a 12% gain over the stock system.

You can buy the Supertrapp from White Brothers at 714-692-3404. Powroll can be reached at powroll@aol.com or call 541-923-1290.

My wife and I both had 98 300ex's. I had an FMF and she had a supertrap EAR. The supertrap was much quieter but the FMF had much more power, snap and NOISE. I don't know how these compare to some of the other pipes.

 

My '98 300EX has a White Bros. pro-meg silencer ($230) and their stainless header pipe ($120). Yeah that's rather pricey, but the exhaust system looks great and is quite corrosion resistant. As far as performance is concerned it pulls a little harder than my friends '96 300ex w/ a Supertrapp system ( did the '96 and before have a smaller 28mm keihen carb? the '98 has a 32mm I understand). Unfortunately it is rather loud. Good Luck
