I am actually really stoked I sold my 1 3/4 Mids for 1 7/8 long tubes I really think all of this work will net some easy hp. Especially if I go with more cubes eventually. Ew at thinking I almost built a car with mids.
wait, what car is this going on?
My ls1/fd what did you think it was for? lol
Wait this isn’t going on the M5?
fuck
i honestly forgot that your FD had an LS1 in it…
the kid has too many toys. we’ve been referring to them by color instead of model.
Yeah my Black one has an ls1 in it and the red on is rotary.
ok, fuck you 
and the blue one has an s62 
So everything is all set after a quick call to Columbia river. 3.5" for the intake, 3" for the y-pipe and 4" for the cat-back. <3
