Thank you @
mswhong. Yes, just res'd catback, cat'd front pipe and overpipe. I have my eye on the P&L and FA20CLUB catted headers, but also want to see if Nameless comes up with a catted option for their long tube. Ideally I'd prefer to stay with one brand, but Perrin isn't doing a header.
The different welding and the catback and front\over pipe is kinda odd, but really, you can't see that unless you're under the car. Yellow or brown color change is normal for stainless exposed to heat, you get the same discoloration around welds. Carbon steel turns such a lovely shade of blue.
Anyway, to the OP, the front/over pipes are well worth it. The car maintains it's reserved nature when you're putting about but very quickly turns aggressive when you get on it.
