my opinion would be dont change it to another RTR exhaust.. look into a ERCM pipe, Ofna pipe dynamite pipe, they are better pipes which will give performance..
I wouldn't use the XL header on either engine, it's too long and won't let the pipe perform properly, use the original X header for better performance. As for the stinger placement, if you go with an ERCM pipe I can make it any way you like.
If you want a better pipe and can't afford the ercm then THS makes one for your savage and right now its only $47 plus shipping from THS web site. I just ordered one for my picco on my tmaxx until i can afford the ercm i want. View attachment 12196 https://www.sitegidget.com/itechapp...er=http://www.thsracing.com/18-cartrucks.html
Above the add to cart button just select item specifics and pipe only if you dont need the rest of the kit. With 1-3 day postal service my total was like $55 and change.
