[LX XLR8R]

im doing the AFR 185,vic jr intake,650 demon,comp cams setup..it made 455 on the dyno using 1 3/4" primariys to 3" to a 14" long collector(MM&FF)...i should just get full 3" right???i was planning on full mac setup with dumps..the motor is going to my DSS 306 for now only sprinning upwards of 6500 but i can def see a 331 or 317 (swap to 750cfm and rev it higher)in the year comming up so this will prepare me better???this motor will also have a close to a 200 hit on it ..what do you tink..i just sold my entire 2 1/2" setup and dont want to buy it again ..i figure if they can make tha much tourque as they did with open 3" exhaust then a full 3" setup should be fine...just tell me yes please
