I purchased one from
@Nick@GotExhaust, the UPR.
I did some research, not just here but other places.
Was it more than $20 amazon one? Yes.
Does come with quality parts as he mentioned above, easy to install.
There is of course a lot of marketing BS.
He gave good price, and has always been helpfully even I didn't purchase anything from him.
Been using it for about 3-4 weeks now. Only issue I have with it. I've added S&B CAI and they don't like each other.
I also purchased the drain kit with it. But haven't added it yet.
