Im looking into the Stillen cat back exhaust. The site shows 2 options with same model# except 1 option has a "P" on the end. Couldnt find a difference in the description and havent heard back from Stillen yet. Does anyone have any idea what the "P" is??

 

I would highly recommend against ordering the exhaust, I ordered it, waited 6 weeks for it to arrive, it came in and did not fit. They manufactured another one, waited 6 weeks, it did not fit. I ended up just getting my money back.

 

I'm sure you had to take pictures to demonstrate to Stillen that it didn't fit right. Care to post those pictures here?

 

I second this. Or atleast please explain what about it didnt fit... I've already placed the order and spoke to 1 of the reps prior to order. If I had an idea of what to possibly expect more specifically that would be helpful.

 

Since you called Stillen and placed an order, what's the difference between the two systems?

 

I was told there is no difference at all and that the "p" is just something they use on their end to track where orders are going. For my area/region to just place the order with the model without the "p".

 

I was thinking possibly Cali spec requirements but they said no difference.
