Attention: TDR Forum Junkies 
Reading past posts the Donaldson mufflers seem to be popular, more specifically the 51" M090544 and the 40" M085171 but, I am curious if anybody is running the 51" M090781, it's a 4" in and 5" out. According to the specs it flows good and it is quieter than the previous two, plus it's $25. 00 cheaper.
Bradhanson had mentioned installing one in November 04 but have not seen any post about it since. Any thoughts on these brands?
