Anybody know anything about the V Flow performance muffler @ performance curve? It says its similar to the 40 series....i guess it the same thing?

 

I have used them before and liked it. Good sound, and performance. Much less expensive.
Though it was on my 04 WRX. People think you can only go with a fart can, and it really pissed some people off when I put a chambered muffler on a Japanese car.
I like the results of it though, and yes very similar to a 40 series

 

nice
