I know this question has been done but I am chasing some noise legal formulas for the muffler setup.....
The setup so far is 347 windsor, 1 3/4' pipes into 4 into 1 merge collector, flaring out to 3 1/2.
I will run cats inserted into the outlets of the merge collector.
The hard part is whether to try and build my own muffler or try a 'bolt on'.
Anyone who is actually running legal pipes, or had legal pipes, what muffler setup did you use?
I was thinking a repackable spiral baffle like in Alfie's gallery, packed with stainless steel wool and with the cats might do it??
Just ordered my merge collectors from Burns Stainless
