Going with a race/street exhaust, 3.5" off of the y-pipe, with short piece of pipe and then a muffler. I have heard the spiral flows and they do have a better sound than the Dynomax bullets. But have read that they eat up more power than the bullet. How much you guys think im leaving on table with the spiral flows?? 3-7 rwhp, or some small dont worry about it.

I would think it would be very very small if any,your talking about just dumping it after the y correct?

i had TD's with bullets and loved it. however a y would bring more rasp so that one's on you.

There is a thread on here about which muffler to go with dumped off a y,there were a few clips of a power stick that sounded pretty good,I agree though there will be rasp for sure,is there a reson why you don't wanna run a catback?lots of people run dumped off the y,I never heard one in person but I would think it would be really loud and lots of rasp,I kinda like rasp though,I just took off my loudmouth1 for true dual set up and I will kinda miss that system,I'm sure when I hear the true duals that will go away though,good luck man
