stay away from the bullits doug. it sounds good at idle and good at WOT. but its sooo loud. at least mine is. car alarms set off just idleing down the street. and where you live the preppy little girly boys will call the cops on you 7 days a week.

yeah I am man. I wanted them for the longest time but of course I want to be different. Im going to try the chambered mufflers or POSSIBLY the Borla ZR1's or whatever theyre called.

Hey Truedaulws6 didn't you do a before dauls and after dyno run? Does the Ultraflow make that popping sound on decel?

I get very little popping with the Ultraflow. It's actually probably the same
but because the muffler is so much quieter you think it's less. The dyno
difference between the Flowmaster race mufflers and the Ultraflow was
5 rwhp. The numbers were 310/305 rwhp (STP not SAE). I say the 5 hp
is worth it for the quietness.

The hp increase from a Flowmaster catback system to the true dual
system was 12 rwhp. I did it more for the sound than the performance,
although I knew the performance would be better.
