2 into 1 out the back systems that run fast

[chief455]

I have 3" crossover into flowmasters that dump.
I've had better fitting systems when I was 15 years old - looks like hell.
Anyone running longtubes into a y-pipe, single middle, cross muffler with 2 tails that actually runs fast quarter miles?
low 11's - 10's?

what size and brand?
thanks!

I read somewhere that a guy was running tens with a mufflex system with the 4 inch y.
