i jsut have an aropseed bomb-series muffler, and it jsut seems to me, that it feels like the car is getting more torque when i have the silencer in, i haven't been able to like run it with it in, and then out to see if their is a speed diference. but i think it just might feel that way because the engine is stressin more. if anyone knows why it might have more power, even though its against the physics of it. jsut tell me why... or am i jsut feeling it stress more???
