Greetings! Turns out that the double mufflers on my ’78 Eleganza need to be replaced and i’m wondering what brands/models people are happy with.
I have the Spintech (single muffler) on my ’76 Birchhaven, and its pretty loud and throaty,
and i’m sure that has a lot to do with it being a 455.
My Eleganza ( w/403 ) has always been pretty quiet and would like to keep it that way :)
I’m currently down in Tijuana again, and AutoZone and Napa here don’t have any of the models (part numbers) that i see on the Interchange… Flowmaster or Walker,... nothing. The installer here is offering a “Flowmaster quality” (generic) single muffler for $150. But i think that’s pretty close (or more than) what i’d probably pay for actual Flowmaster back in CA(?) ...so might not get it fixed this trip. But figured i should start looking into the parts, and the main question: If its indeed best to convert over to a single muffler…. or stay dual.
Thanks for any info and opinions, cheers!
Greg / Los Angeles
