Exhaust

Looking to run new exhaust from headers back, what would you guys recommend I do? Cheaper the better...

Found these: http://cgi.ebay.ca/ws/eBayISAPI.dll?...=STRK:MEWAX:IT
What do you guys think of em?

And is it worth it for me to run single 3" exhaust? or what would be the optimal size pipe to run? I'll probly do an M30 AFM, maybe 19# injectors and mayyyybe MarkD chip afterward if that has any influence on what size of pipe..

Any input is greatly appreciated, thanks!

3" pipe is Turbo piping. Only need 2.5" or smaller.

yea i was thinking it would be a bit too much, so 2.5" would be the best way to go? What about those headers?

Look in my thread its the ones I got I can tell you that for the price they are high quality. In the E46 forums the ebay headers have good rep they are good quality lots of happy people with them and the price well It just cant be beat. Thats why I did not hesitate to get them for my E30.
