Can't decide between the XR-1 Sportsman Racing Muffler or the XR-1 Multicore Racing Muffler.
Which quiet's down the car the most?

I think the oval ones do. The multicores are sold as systems I guess, not sure. I just ordered an XR-1 round to go just before my GMMG. It seems like the XR-1s are popular because of quality and sound. We'll see....
