Looks like they have to come in from the bottom. Just got done putting Kooks on my buddies GTO, and passenger came in from the bottom, and the drivers from the top. How hard is it on the TBSS. Plan on getting the Kooks myself.
Wondering how many hours it would take for two mechanically enclined people to do it. Is a lift a must? Turning my SS in for an awd 07. Modding the f*&^ outta the new one. Seems like Kooks along with stainless works exhaust is the way to go. Is the Y pipe with cats designed well? Havent seen any pics. May just do it all at once. Mid 13's is cool, feels slow now. Must go faster.
Gotta get some band clamps MT.. I had problems with those clamps.. Just one.. but enough to give my wideband a hard time. BTW header install is not bad, its just time consuming. I assume you have access to a lift. Also.. Cut the stock Y pipe.. Might want to change spark plugs while you are at it.
