Possibe??Feed pipe through catalytic con to "Look" legal?

[DLo]

Has anyone ever heard or done this. Run a pipe straight through the catalytic converter to give the affect of a straight cat wile still having the apperence of a legal cat attacthed to the car?

Just gut the cat and you'll get the same result.
However, a good mechanic/inspecter will notice that right away (noise, smell)

agreed.....and it is an easier mod too

running a pipe is still a better result (smoother flow) but yes youll fail smog easy, you can smell it a mile away

My asking was to go the cheaper route then fixing the current one. One one end of the cat the flange has broken and needs to be replaced. Was going for the kill two birds with one stone.

Oh well, back to looking for a place to put in a universal cat cheap.

just get a good flowing one, stay legal, and have the performance. oh and my dad says that people where doing the "fake cat" 20 years ago.

I knew I was not the first to come up with it....jus wanted to know if anyone had done it with a small 4 cylinder before. Lots diffrent then a big ol' V8 from the past now.

I put a test pipe on my 240SX (KA24DE 2.4L 4cylinder). I liked it but it was SUPER loud. It didn't smell at all either with 180k miles.

My Camry with stock cat and 90k miles smells like rotten eggs sometimes out the exhaust now... I can just immagine when I get my test pipe on here

yeh i initally left my stpock cat inwhen i did my exhaust now i got a hi flo wmagnaflow, and its a lot louder + tougher sounding + deeper.
