wow, that is terribly expensive for such a shotty product in my opinion.
doesn't even have rolled ends on the piping, just some weld material? Also, it doesn't look like it fits the greatest. not to mention it uses cheap worm groove clamps..
Basically, you are paying 220 for two couplers, 4 clamps and less than a foot of piping + 40$ for a knockoff HKS BOV.. Seems like a terrible deal all around to me.
The stock cold pipe goes from ~2" to 2.5" at the throttle body. You wouldn't be gaining much at all here if anything, other than a BOV.
I could probably make an identical setup to that but with better fitment, rolled ends and t-bolt clamps for about half the price and everything would be higher quality.
