My friend has a 1997 talon tsi. He wants to get a 3 inch downpipe and cat-back. If he does not port his exhaust maniford and o2 housing right away will he have any problems? On the web site it says that you must do this. Will he get boost creep or anything else. If you have a buschur set up respond.
. I give up. Hopefully my ramblings give you guys some ideas... 
) Good luck.
