Ok, its about that time I change up my exhaust. I want to run either a 2.5 to a Tanabe Tuner Medallion hyper spec muffler or a 2.75 to a Tanabe Muffler.
Is 2.75" too big for my 4G64?
this is the muffler:

and I will get the piping done by a local speed shop.
It's way too big of a far can. That has been the consensus for years. the stock is 2.25 and appear to be perfect, unless your car is forced fed.
largest i would go on an N/A 4 banger would be 2.5"
piping 2.25 NA I4, up to 2.75-3.0 if you are HEAVILY boosted.
muffler size isn't as important as piping size. you could run a 2.5 inlet 5" outlet and it wouldn't make much of a difference performance wise.
im a 4 banger w/ 3 inch
your legacy is turbo'd though.Quote:
