On a turbo car the bigger the exhaust the better!
3" would be best coz its quite common and cheap.
what about back pressure? something too big may do more harm than good, i say no larger than 3"
yeah i wouldnt go any bigger then 3"
turbo size, expected responsiveness & future upgrades should be taken into consideration
if you've got a small turbo and you're going to keep it that way go 2.5" otherwise 3" max
imo
On a N/A car, backpressure is Necessary, but on a Force inducted car it is actually better to have alarger exhaust as back pressure isnt necessary, and wastegas should exit as fast as possible in order to make boost.
But your right dont go bigger than 3"
i ahve 3'' on my 4agte and works great
