hey, i have a 99 400ex, whats the best pipe to get me the most performance, money is not an option, thanks!!!

 

THE BEST 400ex PIPE I KNOW OF IS MADE BY A LOCAL SHOP IT ADDS A LOT OF POWER!!!!!!!!!!!!!!!!!!!!!!! THE WEBSITE IS www.gthunder.com AND THE SITE SHOWS SOME DYNO's THE PHONE NUMBER IS 1-330-674-7122

COBRA EXHAUST! WOW THEIR SO AWESOME!!!!! THEY ADD LIKE 18 HORSEPOWER! TRUST ME ON THIS ONE! lol

 

i would go with the DOUBLE-BARREL from duncan-racing.....it adds alot of power because it allows both pipes to flow better because it doesn't cut back on either pipe,,,,,basically it has better exhaust flow....it may be a little higher ( right over $500 bucks ) but it is worth it my brother has one and it was worth it.....trust me it sounds great with power to back it up.

 

The Big Gun exhaust is an excellent and quiet pipe.

 

i want something loud

 

If i were you i would go with the CT Racing pipe i have it on my 400 and its real nice. It adds a lot of power through out the whole powerband and it it really loud

 

I am very happy with my White Brothers E-series pipe.

Get an old copy of DirtWheels, they did a pipe shootout on the 400EX, the White Bros, E-series won. I looked at the dyno charts they had but I must say, I wasn't impressed with any of them. The HP increases were minimal as compared to the stock pipe.

 

The White brothers E series didnt win it came in second the CT Racing Came in first
