It was already installed when i purchased it new in late 2002. Today I took off the cat converters and replaced them with straight pipes i got from autozone, each pipe was approx 18" long. It was a quick bolt on and off job, im keeping the cat conv's in the garage so i can do a swap back when it comes time to do an inspection, good thing everything is just bolted on!
After i got the cats off i disconnected the rear 02 sensors and got them off aswell. After i installed the pipes and was ready to put back the 02 rear sensors i wrapped the sensor tips with hvy duty aluminum foil and secured it with sm small guage wire then screwed them back in place. Everything went together very smooth and looks good so i started the truck and was very surprised on how loud and bad *** it sounds now.
I went on a test run to hear the exhaust and its super loud, i also was watching my dash for any lights that may come on do to not having cats on it and messing with the sensors. No ck engine lt or anything else came on so i guess the foil worked and fooled the rear sensors. I also noticed that my exhaust would occasionaly make a cracking sound after a stop and go. Is this because the age and size of the mufflers? If i replce them with some new bigger flowmasters will the cracking sound go away?
Any opinions would be great! Thanks
First time I have heard of "screwed them back in place".
Let's hope that continues to work for you. Usually if you wrap them in tin foil you use a plug for the bung hole and tie sensors safely out of the way. Good luck..
