im searching for the best pipe to increase power and a screamy sound

how more power give a k&n filter,jet kit,high compresion piston,racing cam on my 98 300ex

i know a 333cc bore kit whit 38mm carb and all the other mods give like 35hp

 

The FMF Megamax is the best for power and it is the lowdest.

300ex... The Big Red Machine

 

the DG series pipes sound awesome (like a truck w/ glasspacks, loud!!!!!!!) it also boostes power a lot. it gives a lot more on top and a big pick up in the low,mid. it will be necesary to re-jet after slapping it on becouse it'll lean out.
