Since I have to replace my catalytic converter, I was thinking of buying a MagnaFlow hi-performance exhaust system with their hi-flow catalytic converter. I called my local shop and was told that they don't have one listed for a 2003. Question 1 - does anyone know if an exhaust system for an 04 will fit an 03 with no problems ? Mine is a regular cab short bed with a 5.3 engine and it's in California. Question 2 - if I get the exhaust system and do not also get an air intake system installed at the same time, will I fail to get all of the potential benefit from the better exhaust system ?

 

I have a 00/Z71 W/the Total MagnaFlow Package -> BUT!@! I if I am correct, as of 10/15/06, I believe that MagnaFlow does NOW offer a Brand New Cat w/Y-Pipe plus the Cat Back system for you. I would suggest that you not go with a Bassani System as they don't really have one, just parts welded by the shop using their Universal Cats w/NO Y-PIPE(everything has to be hand built=$$$) and a Corvette Similar Muffler with X-pipe inside. They usually have to cut your cats off and weld in the Cats, using your original Y/Pipe for 02 Sensor placement and that’s just BS ->(Call Bassani and ask Darryl himself). I run the entire MagnaFlow system and just passed smog in September in 4 mins. You need to also, and this is a no buts deal, buy new 02 Sensors - REAL OEM - Front/Back, 4 in all and make sure you know which is which. The plug/connectors for the sensors are on top of the frame rail, 8"-10" from each sensor, piece of cake. If you haven't bought a Programmer yet, go right on by the Hypertec (old news) to the Demon. YOU CAN BORROW ANY DEMON FOR THIS, NO NEED TO BUY ONE JUST TO CLEAR CODES. I bought a used one just to clear all codes and do not use its power or other settings; (I have a re-programmed PCM) -> Clearing codes will be important as you get more into performance for your truck.
AGAIN, just because I use a product doesn't mean it is any better than another, just my experience and hard research have taken me here. Just trying to save you money and help you stay away from the “BUMMER-FACTOR.�
