Hey guys
I know this topic was thrashed on the old site, but what is the ultimate exhaust set up for a 4JB1 intercooled engine?
At this stage i am looking at going to go 3" dump pipe in to 2.5" with a single Coby, any pros or cons?
I also have the 3.1 oil filter housing to swap if the 3" pipe is in the way
Thanks
