My set-up is dual dynomax bullets w/ x-pipe (still have the cats). I had my 4inx22in chrome tips put back on today. I had them w/ my flowmasters, haven't had them on the bullets until now. All I can say is, Damn! This sounds better than anything I had before! It is real deep and aggresive sounding when just driving around. When I get on it, it is freakin' loud & deep as hell! I love it. It sounds weird but, I actually felt a gain in my low-end torque, I thought I would loss a little.

Also, when I had it dumped, it would resonate real bad inside the cab. Now, it is about 1/2 as loud, helps hear the radio.
