Sup guys, Im building my down pipe for my turbo system and being that my car comes with oxigien sensor right in the exhaust manifold, where should I put it right now that im going turbo?
Can anyone of you guys provide this info? and if you guys have pictures even better.
Also can I put my pyrometer around the same area and what will be a good price for a pyrometer, I have seen a few for quite some money. I want to know this so the guy that is going to build my entire exhaust system knows what I want and how I want it.
Also while I'm at it, is the apex N1 muffler the best bet if I want a high performance muffler in stainless steel without the loud noise. also does anyone knows the piping size of this muffler? Any other mufflers you guys will recomend that matches my discription, stainless steel, at leat 2 1/2 diameter, and be able to comply with the Noise restrictions law, and last but not least, it got to look cool.
thank you guys. Can't wait to finish my baby.
