Hi Guys,
I got the RTR (I was missing a good controler and a start box so it was the way to go...).
I have sold the 454 engine, and I am planning on getting either the Werks b5 or the OS .25XZ (P).
I am selling the engine, but keeping the stock exhaust.
Can you tell me if this exhaust will be decent with those engines? I am planning on getting a JP2/3, but I also have to get decent servos and an engine warmer (I live in Canada, and breakin the engine early in the season means low temps).
I would like to delay a bit (if feasible) the acquisition of the exhaust.
I plan on racing (sportsman, not competition) and I am wondering if those engines are good enough. I am a bit worried about having a .21 in such a big truggy, even though everyone seem to run on .21

Also I had a really great time with OS in the past (Revo) but I have never seen a Werks.
Thanks for your answers!
