Hi all,

 

My exhaust is corroded and i need a new 1 however i have seen some back boxes i like but the pipe size from the back is 3"....am i right in saying standard turbos have 2.5" requirement? If wo how would i either get the backboxes smaller piping or increase turbo 1s?

 

Sorry if question sounds silly

 

Thanks

Stock size is 2", most aftermarket exhausts are 2.5" but 3" are available for even more gains. Where are you replacing from?

Well if stock is 2" and i need to get it to 3"...where should i replace from?...was orininally fron the cat back...
