What I don't like is that the exhaust is almost too loud for a daily driver when starting or flattening the throttle (not mush), but fine for MSRA or NSRA fairground driving. I like that the exhaust is quiet on the highway. This is a straight muffler so be aware of that. I installed two on a 1946 Ford coupe with a stock Chevy 350 engine with cast manifolds and TPI. I'm 73, maybe that's me.
