Not to mention why would you break apart a set of downpipes that cost somewhere north of $1500 each?
Do some research first. I came from the audi tuning world. Guttin the cats on DP's would give the car an increase in HP. Do a search on Audiworld.com
and there are endless dyno charts on piggie pipes.
