has anyone fitted stainless 4 branch, unequal lenght, and found the exhaust note to have sounded tinny? i have a full straiht thru 3in decat stainles system but had the standard cast headers on it. and it had a great flat four burble. but got a crack on the up pipe so though i would make the whole thing stainles by buying a 4 branch. but it sounds real tinny and is !Removed! real loud now. do i get a standard one to get the deep burble back on or would it make a difference by heat wrapping the front pipes? would that muffle the tinny sound and bring back the deep burble?
