PLM Catted 200 Cell Downpipe

Perfect for the price, provides with absolutely everything you’ll need gives it a nice deep tone with some top end rasp. Install took roughly 2 hours with right tools.

Great option for an upgrade

Bolted up easy enough. Maybe use some of the light hold loctite on the wideband **** up top of your not using it. I tightened mine initially and it vibrated out, but had stayed out since reinstalling. Love the sound of my exhaust now. Would definitely buy again.
