Silverline Stainless system would be an excellent choice. . FWIW. . When I had a phone conversation with the Silverline Rep,, He ststed that the only manufacturer that build a muffler with the quality level equal to theirs was MBRP!!!!. . He also stated that the aluminumized version of Silverline (and MBRP for that matter) did NOT use the same muffler as the stainless systems... Always made me wonder if somewhere up the food chain that Silverline and MBRP were one and the same????... . Maybe designed as a group effort, then two different individuals packaged them under different names.
Note that about the same time Genos phased out Silverline, the smoothly slid MBRP right in there... . hhhhhmmmmm... .
Anyway... Either of them are great systems, spring for the 409 stainless as a minimum... I actually got the 304 polished system for the 409 price...
