U may be able to find a used one for like 80 bucks...
I'd buy a new one though. depending on the brand they can get up there in price..
Also, just my opinion. But flowmasters sound like garbage with the o/r pipes.
If i were you i'd eitherrr just buy a pair of slp 1 resonators and swap em with the flow masters.
Or, buy an o/r Pipe and get some spintechs.
