I used to own an Evo 8 and ran a full catback (greddy) with an N1 tip. Tip was 3 inches, im a fan of the large tip. The dual pipes are nice but not for me. So basically im looking for everyone's advice / recommendations because im a new speed3 owner. I want to increase the airflow / hp. So I was thinking about a catback with a down pipe and a 3" tip. If you could provide pics if you have something similar as well as brands and where to buy that would be a big help!

cat-backs on turbo'd cars really don't net too much. the cars already come stock with a 2.5" exhaust which is MORE than open enough for these cars. lots of people run turboback exhausts which can be completed in a two piece design, or a three piece design depending on which brands you go with.
CP-e/Cobb/SW/Exhaust-depot 3" dp = 2 piece design ...DP replaces both cats and then you have your stock CBE or aftermarket CBE
corksport/turbo-xs 3" dp + 3" racepipe = 3 piece design.. DP -- Racepipe -- catback. both the dp and rp replace 1 cat respectively and then again you have either your stock CBE or aftermarket CBE.
you'll have pretty similar performance upgrades with both routes as well as with the stock cbe or an aftermarket cbe. its nice to know that for around $300-350 you can pretty much grab 15-25hp/15-25tq if you were to go with corksport or turbo-xs' dp/rp combo. hope all of this helps!
p.s. make sure you search for "turbo smoking issue" with the k04's on our cars. this is something everyone should read and understand before wanting to go with a full TBE.
