OK, so I just got my new exhaust done last week and I already want to make it louder. BigBlue5.4 and avfrog, recomended the 94106 magnaflow cats. i want the loudest ones pretty much lol, its just My exhaust guy thinks i should invest in getting the ones with the O2 sensor bungs already in them becuase he's going to drill them out anyway and charge me an extra $200 for drilling. He said with the 94106's bought, drilled and installed im about $350 out the door.
Does this sound right?
are there cats with the bungs already in them that would workout to be cheaper?

Because I am in canada, there may be a slight increase in pricing .

any thoughts an comments would appreciated

thanks!

 

when i done this with my 04 my exhaust guy cut off the ends of the pipe with the c02 holes in them and just welded them to my new cats.

 

^thats what i thought he could do, but he said that 94106's are longer and that there wont be enough cord left for the sensors to go after the cats.

 

no if he knows what the heck hes doing he can. You got 4 cats right?

 

But anyways man ill take it someplace else. Cause i got my high flow, jba shortys, xpipe, dido mufffler installed for 450. thats pretty cheap.

 

yea that is pretty cheap, no i only have 2 cats on my truck...

 

well he should still be able too

 

94106's are pretty much the gold standard around here. My guy mounted the O2's on the actual casing passed all the innards. That way the holes in the heat shield could still be used.

 

ok, ill talk to him and see. if not the closest guy is like an hour away lol
thanks for the help!

 

Take a pair of 94106's to a different shop.

 

The muffler shop charged me extra to drill into the cats as well. It was $50 for both, and the for the installation and drilling together it was $140. They said that it was a tight squeeze to make the o2 sensor reach, and that they couldnt install behind the cat without an extension.

I love the final result, it really "MADE" my exhaust!!

 

^
lol, ok, thanks for your help!

 

go with the 94106s

 

part # 94136 has the bung built in and only about $9 more. Same cat as the 94106. Check it out on magnaflow.com

 

Thanks for the heads up...

They are a $6.18 difference per on performancepeddler.com (using "clubgp" promo code)
