this is for my 06 trailblazer ss. I allready have a mandrel bent 3 inch cat back set up i put on but i see y pipes are only 2.5 inches. Does anyone make 3 inch collectors to a 3 inch y pipe in any gm truck application right now so i can talk to them. reason i need 3 inch is because ill be putting a magnacharger on it and i want that baby to breath.

 

mine is a 3"ORY (pacesetters), dont know if they make them for the TBSS yet... give a sponsor a call, I bought mine from speed engineering>>>>>

 

someone had just a 3" ory for sale in the sale section....

 

I have a 3" ORY too... its not too much esp if you are planning on a blower... it will flow nicely.

 

I know someone in norcal that can me you a custom y-pipe. PM me if interested.
