With the L03, you have engine code E. The eighth character denotes the engine code.
But - that doesn't mean you necessarily have to use the catback for that application. If I'm not mistaken, I believe 66-16820 has a 2-1/2" intermediate pipe, and the other two have a 3" pipe. 66-16822 used to be around $200, but apparently they were selling too many of those. BTW, if you find it cheaper, it comes with a 4-bolt flange which can be cut off and a piece of pipe spliced in its place. Hope this helps...

 

so if thats true about the 2 1/2 pipe could i order one with 3in pipe? if so, which one of the other 2 can i order?

 

They all have 3'' I pipe. The only difference is the cheap one has a rectangular 4 bolt flange that hooks to the cat. I ordered that one, had it cut off and welded up.

 

and let me guess.. the cheap one is the one i need?

 

Look at the cat on your car, if it has a 4 bolt flange at the end that hooks to the stock I pipe , then yes, but I don't think you do.

 

ok thanks mark... i am in love with the sound of hookers =) your car sounds beautiful

 

Wait till I post a new sound clip next week.
