Before turbos I always had Fowmasters and LOVED the sound. The last time with them was with a homemade X pipe/expansion chamber and dumped at the rear. The thing sounded like an animal! It added 100+ HP at the ear without a doubt!!
LoL! If any of y'all were on the PT in 2000 or so and saw it throw parts on the dyno at Comp, then you can attest!
I tried with the flows for a year or so with the turbos, but it didn't sound right and ended up changing them for some straight thru Dynomax bullets. After we built the TQ arm setup, I had to go with single 4" exhaust and ended up getting a Magnaflow and really like the way it sounds. Nowhere near as good as a high compression engine with flows, but still pretty good tone and volume.
So me personally, I like to hear a deep rumble with little resonance and not obnoxiously loud at WoT.
This is the best video I have with the current exhaust.
