question...w/ noise and exhuast
alright, here is my problem. i have the helix dp and the bosal catback with a wagon. now i have problems mating up with dp and catback and found out recently that is because the dp is flat flange and cat back is doughnut. right now i used a paste called muffler mender and it has sealed it pretty well...pretty well means very slight slight leakage on the top of the flange. however the exhaust is very droney, or reverberating (whichever makes more sense to you) at a low rpm(anything below 2500) my question is if i get this welded to correctly mate up will this drone go away. i was thinking about combining some part of the bosal and stock cat back to see if i find a better combo with noise and flow. since i have the dp and cat back sealed i was thinking about putting the stock axle back on and leaving the bosal intermediate pipe. any advice opinions or similar experience would help....or hell if you want to buy my bosal cat back let me know. its the dual tip.
