im going to buy a pipe and manifold from redcat for my 1/10 truck, i got it from exceed but its the same truck. does all of the hardware come with it or do i have to buy it?

it just comes with the pipe, you use the old coupler, thats if its the 1/10, the 1/8 comes with everything

you'll also need to get some new exhaust manifold gaskets, part number 02299, if you don't already have some.
