i removed my muffler 10 years ago. the cats aways kept it quiet enough. had a little rumble but nothing bad. well now my cats stopped up. i had them removed today. even with single exhaust it is absolutely ridiculous now! lol

whats a decent single inlet and outlet muffler for a good price that will flow ok and keep things tolerable?

 

Put new cats on it, your ears and everyone's nose that has to follow you will thank you.

 

Isn't it unlegal not to have CATS, depending on year which may be something back to a 70's model?
Even a 10 year old minimum vehicle would still require cats? Maybe no inspection in your place but still means you've removed federally mandated equipment?

Wont you also have check engine light without a cat as the gasses aren't properly metered throwing a light, and running rich and wasting money on low fuel economy?

 

um yeah... i just got off the phone with the exaust shop. they ordered 4 new catalytic converters from the dealer and i have an appointment to have them installed at 9am tomorrow.

 

how much does that cost ?

 

Make sure your plug circuit in great condition ,misfires burn cats out. Its important to have good o2's ,they determine fuel mixture along with maf . Too much unburnt fuel will burn them out same as misfires .

 

yep. misfires killed my cat. i let bad plugs go too long. its right as rain today tho. no codes and running well.

 

about 800
