Tanabe exhaust question
for those with the super hyper spec exhaust, what is the pipe diamater, i am pretty sure its 2.5, but i want to make dead sure, i need a new muffler, oh and for those that have it or are thinking of purchassing,
after some dyno tuning i found that without an exhaust i dynoed 195whp, with the exhaust 170whp, sooo, something's not right there guys, you might wanan lookinto something else, me personally i am buying just a muffler to weld on there.
