using bullets vs flowmasters
2-4 decibals for the Dynomax Bullets. Will sound good but will be loud. Your only planning on drag racing though right? May be too loud for a daily driver. (decibal rating is from Summit racing) Definitely will have flow, it is basically a large diameter glass pack. Usually us 40 series flowmasters on cars people drive daily, nice sound without being overwhelming. There are race series flowmasters in fact people have been comparing the 10 series flowmaster with the Dynomax bullet. May want to do some research and see what your options are, you can find something that will give flow without haveing way too much sound. I am not saying one is better than the other, so you know:)
