Do i need 02 extensions to install longtube headers...????

yes. the o2 bung is located alot farther back on most longtube headers so you will need extensions. if you are using rear o2's, you may need extensions also, but i guess it depends on what midpipe your using. i used mac longtubes with an offroad mac h pipe, and they both required extensions.

Call summit, they have them. They will have a little tit you have to shave off so make sure you read the instructions.
