Well I'm a cheap bast@rd. I ordered the Sosi X-Pipe. Spoke to the guys over there who were very informative and stood behind their product. I was really looking into the Challenge and almost ordered it but I thought I could achieve the same with the Sosi pipe. The installation is pretty straightforward and one thing that was important was not to get any CELs.
Next is going to be a tune. Depending the results I will more than likely get some HFC to replace the stock primaries. Any specific 200cell cats anyone can recommend? I saw Magnaflow makes a 2.5" 200 cell metal catalyst in a stainless steel body for $100 each.
I don't mind experimenting with the lower-end stuff. I know the can of worms that could possibly be opened. Along with the shop we will take a look at how it goes. If the setup ends up being crap, we toss it. No big loss. I really do appreciate the hardwork and craftsmanship some of the better companies produce but that doesn't mean it should be my only choice. We'll see where it goes.
Any recommendations on a specific tune guys? Evolve... no PM?
I understand that this car isn't a torque monster, nor can it be made that way, I was looking into ways to add a little more pep to its step.
Thanks for all the info so far guys.
