Our track is tight so acceleration is very welcome but i also need a good average fuel time. How is run time comapared betwen 2652 and 2660 and what muffler is normally used for these exhaust systems. Thanks and hope to hear from you as soon as possible. Thanks
Nova 2660 with 5 fin manifold. If you don't mind to spend a little more, Capricorn 2662 would be the best bet.
