i'm thinking of putting an exhaust system on my fc but i would like to no which one is better performance wise. duel exhaust or a single exhaust system?

 

you can save weight with a single and just get bigger piping... id go single.

 

No offense, but... Why is this in Race Car Tech?

 

CUZ I WANTED TO GET THE BEST OPERFORMANCE OUT OF THE FC TO LIKE U NO MAKE IT GO FASTER

 

In that case, go here

and ask the question with your exhasut question in the subject line. you'll get your answer over there sooner than here.

 

since its a race car and you dont have to worry about noise or it being street legal or anything, i would do single straight pipe. lighter, easier to make, cheaper, ect. also it will give you better top end since you dont need much low end on a race car...
