you dont need all that much punch down that low anyway

like if you were racing, you would not start that low, atleast i wouldnt

i didnt seem to loose anything with my duals but i lost a butload of top end pull when i sold my 1st set of duals and went with ory and hooker catback

now im back to duals 4 good

even people that ride in my car tell me its night and day difference the way it just keeps pulling with my duals

i lost a butload too, with true duals but i decided go to 2 1/2 instead of what i'm running now which is 3 inch. it'll be about a month until i get the new setup in. good luck.

Well, I ran her out on the hiway, above 3500. there is no comparison, car seemed to pull much better, maybe the new sound was throwing m e off, but staying with the 3" duals.No drone whatsoever

LT's tend to trade low-end for high-end I believe. So this is nothing out of the ordinary. I noticed my biggest gains up top but I also gained some down low. I attribute this to the H-pipe.

perhaps you need some tuning now with the headers...you might be running extra rich down low and that will give you a 'boggy' feel.

What is the part number of the ultra flos you used? Can you post sound clips?
