I am going to buy a new performance exhaust system for my Mojave and want to know if Supertrapp IDS2 or White Bros. S-Bend will give a better hp increase. Thanks for any and all replies.

 

I went for the wb s-bend. If you got the $$ go for the wb megaphone. Its been rated at 5-7 hp gain where the s-bend 3-5. I've been impressed so far on my 400ex.

 

i have also considered just now the big gun exhaust which shaves weight(about 7 pounds) and adds around 5 horsepower. the price is $370.95 which is around $130 more that WB or Supertrapp. also the pipes is quiet around 98db and helps the engine run cooler by about one-half the usual. does anyone know an approximate horsepower gain and/or the amount of weight shaved by the pipe????

 

My experience with the Big Gun systems is that they are a good torque setup with exhagerated hp claims.
