I have put these on a car before. They are very nice and aren’t nearly as loud as a resonator or glass pack

how heavy are these compared to a magnaflow straight through style muffler?

How long is it… the elise needs an exhaust…

I would say lighter than the magnaflow straight 4" round. They are a bit heavier than a glass pack.

They sound good on a V8, don’t know how they would sound on a 4 cyl.

i assume it would sound better than a stupid magnaflow tho?

i had a flowmaster 50 on my 240 and it sounded nice… but that was 6 cyl.  
and i don’t think i have the room for it…

Opening clip = open headers  
the rest = twin moroso spiralflows off my long tubes

didnt quiet it down enough for my use, but, wasnt exactly a full exhuast setup either
