smog could be a drawback but to be honest im not too worried. what about loss of power? I do have a larger diameter intake so would this increase power it at all since it can breathe a little better?

Get the Fabspeed pipes. No regrets whatsoever. Now I would like to get some good quality headers and reflash the dme to RoW.

Don't know how Cali would like that header upgrade though. Tennessee is a great state to live in! No one here knows what a smog test is...

im just going to have a local shop cut me some pipe. I see no need to pay fabspeed 500 dollars for something I got quoted 40 per side... but I had to cut the cats off myself so I guess I pay the price in other ways.

there is actually an alternative:
get a set of secondary cats from a junkyard. Now get rid of whatever's inside the cat housing (I leave it up to your imagination on how to do that).
Now you have something which looks totally stock, was very cheap and has the same effect like bypass pipes (more torque)

that was a thought. BUT I found a place that bent pipe for 40 dollars total. So a 500 dollar mod so far cost me 40. Hopefully they will match up well. Ill have it done today, I have a AX tomorrow so we will see. the results.

Is that pipe stainless steel pipe? If not, expect to replace rusted out pipe in short order.

Also, did they fabricate the triangular flange on those pipes that mates with the headers like the fabspeed pipes? If so, I'd say you got a very good deal.
