i want to get the toomey exhaust for my 450 but its just a slip on i should be able to get more power with a full exhaust can i get the toomey slip on and then get a diffrent head pipe and how much more will it give me if it works

 

i whould guess about 3 hp for the header. but ive herd for the yfz450 the dasa, yoshi or nmotion 9 inch are the best pipes for it.

 

so i can get a toomey slip on and a diffrent header and it will work

 

if it does work what header should i go with

 

dont know if it will work. some of the bends chould be different. not to sure on that part.

 

yeah thats what worries me are the bends my friend got new exhaust and the muffler has a diffrent bend in it then stock but id imagine toomey has the same bend as stock since its a slip on

 

i whould go with the dasa or the nmotion 9' if i were you. both make very good hp. i think one is one low end and one is more high end. (not sure which one is which) and they are proven. there is a very good thread at yfzcentral if you want to look it up. a guy got a ton of exhaust system and dyno them same machine.

 

yeah im shure i no i want mid to top end ill look into it thanks for the information

 

The toomey pipe will not work with another header because the bolt hole patterns do not line up but i really dont think you need a header with this pipe I ride with five of my friends and we all have the same things done to our bikes except the exhaust they run yoshi , fmf , white brother, ron woods, and nmotion and I beat them all up sand mountain by about 5 bike lengths

 

if you want performance get a full system...people dont buy slip ons and headers seperate. they buy systems...slip on will just add a different sound and new looks...
