I presently have Flowtech mufflers on my JEEP (small block Chevy with a performer cam). They sound fine but I would a little more of a throaty, lounder sound. I put them on about 7 years ago and I think they are the basic flow tech mufflers. Do you have and information on sound level vs. type and some way of comprehending the noise level. I am not looking for "cherry bomb" sound but do want a little more noise.
