best cat placement

patrickrobare · 10-05-2012, 11:46 AM

Im about to buy a catless downpipe and make my own exhaust system. I plan on running a straight through magniflow muffler in the midpipe and 3in straight back that splits into two sorta like stock. Is it better to buy a catted downpipe or put a cat between the muffler in the midpipe and downpipe? Or should i just forget the pipe?

Do you want the catalyst to perform actual conversion or are you merely trying to appear emissions compliant?

I want it so that i wont get a huge fine if it gets sniffed.

No need for those pesky things here.

Lol what do you do for inspection?

Paidfor · 10-05-2012, 05:33 PM

Whats a inspection lol
nah seriously tho .......im in northern mississippi and never seen or heard of a inspection station anywhere close, We pay 5 dollars a year for a State Insp sticker...all they do is make sure your headlights,turn signals and horn work.
We got dumbasses runnin around with open downpipes and **** lol
The state just isnt concerned with the issue i guess.

I've never gotten a sniffer test in New York, I don't understand why people keep asking me what I do about inspections without a cat. I say I pay the man and I'm good to go. There's not even any garages around here that have a sniffer. Hooray for a part of the northeast more akin to the deep south.

put the cat right after the downpipe, then make a straight pipe matching the cat length. make it easy to change and you have a test pipe for full time use, and a cat for sniffer time.
