and you will get a better A/F reading a little farther down the exhaust line as well...like about 10" before the first cat...and it will be cheaper to have it welded in...just go to a Tuffy...I think it cost me like 10 bucks or something...
if you mount it in one of the 4 pipes you will only get readings for that one cylinder...moutned in the collector after all 4 have met will give you a reading for that bank....that is where i would mount it
JB Weld...doesn't work as good as everyone thinks.That stuff about
fixing cracked engine block's like they advertise is "BS".I would definitely
weld it in like Chris said...
