I've been trying to buy a Magnaflow catback for this truck and have hit a wall. There are units listed for 2005 Standard cab but not 2004. I know they did a change around may??2004 on the exhaust and mine is a may 2004 build date. What can I measure or check to be sure if I order a 2005 spec unit, that it will fit? A phone call to Magnaflow was no help.

Thanks, I'm sure someone has a Standard cab with this problem....

I think its something to do with the shock placement with 2004s & 2005s. Most kits for 2005s+ wont fit 2004s, given that they are the exact same truck.

If you cannot find the result for your question I would suggest buying the muffler and tip(s) you want have have a shop install it all.

 

It might be cheaper to buy the muffler and tip and get your local muffler shop to run the pipe.
