I have a Greddy 2.5" cat back for a 2+0 that isn't moving, so rather than give it away, I plan to make it work on my 2+2. I have 3" to 2,5" TT test pipes already (when I go TT) I wouldn't even think of using the NA exhaust on a TT - lol - If the test pipes end in the same location as you say, that allows me to build/mod the Greddy exhaust now in NA form while I can still drive it to a friends shop with exhaust. Thanks!
