Has anyone here had their cats gutted? If so, Did you get a CEL anytime after? Will this effect my 02 sensors?

I've heard of a couple of people gutting them without a problem. The only problem you may have with your O2's is if they don't heat up enough because of the high flow capacity.

thanks brudda

02's will be fine but your cat monitors will go "cattywhompus"(yes its a technical term) those are the 02's that are downstreem from the cats. summitt sells mil eliminators i dont know if they work or not though but thats where they are for

that's only on the Gen 2's, by looking at his sig he's got a Gen1

You are COMPLETELY wasting your time gutting your cats. The amount of improvement over stock is SO small it is NOT worth it.

gen one only have 1 set of o2's and no cat monitors?

Im looking for a louder, raspier exhaust tone. Not neccessarily more hp.

That's right, no O2's behind the cats

damn you gen 1 guys are lucky:(

What about the 96? Its OBDII like the Gen II

get dual...
Durr...... I already have daul exhaust..... 2.5" from the cats back, into a d/d magnaflow(perforated tru-x core).

let me check on the 96 i dont think obdII matters for that

That'd be cool. I'll like to know, I know it shares some of the Gen II emision crap.

96 has got monitors sorry for you too

I thought so. Is what it is.

Y would you want it louder.. ditch the magnaflow and get a flowmaster d.i/d.o.

I want it louder cause its my car and I will do what I want with it. If you knew anything, youd know that flowmasters dont flow for sh1t, and they're too expensive. I payed 79.95 for a d/d muffler, Their single 40 series are the same price and sound like sh1t.

Probably get alot of cabin noise.

I dont care about cabin noise. I care about vrrooom vroomm noise! hah

How is it now with the Magne-Flow in the car.

Plus gutted cats sound so nasty ass and raspy IMHO Burble, burble, burble.

Theres a tad bit of drone, but I like the overall sound of it. I just want it to be louder and raspier.

Cool, thanks.

It's gonna sound like crap, but do what you want.

Have you done it before? On a mark viii, with this same exhaust setup?

Here is a file that has flowmaster sound clips.

GO w/ a tru duel setup.........

He already has a true dual setup. I was thinking of gutting mine as well, but more for the reason that mine are clogged and smell nasty sometimes when I get on it.

I MEAN TWO MUFFLERS MIDBODY MOUNT

Did they used to make guitar strings from cat-gut?
I remember buying "test pipes" years ago at the parts store...for test purposes only;) to see if our cats were clogged......

Midbody mounted mufflers doesnt mean TRUE DAULS! I was thinking about doing that a while ago but there isnt much room and they would hang down.

did you see the pics i post on the above post W/ THE TWO midmount mufflers. i did it w/ spintech mufflers. spintech has thin square mufflers that will alow two midmount mufflers

I actually contemplated using glasspacks like that........

Looks like that setup was on a b tird!


A 95 TBIRD bout the same for a mark.

yah I know! The mark viii is on a heavily modified mn12 platform....

leave your cats alone! they are on the car for a reason. so it will pass emissions, if you wanna get rid of em then buy a whole new set-up.

Yeah but I don't care about emissions, but I do care when my car smells like crap.

I had my cats gutted in my other mk8 and it did not smell more then usual.

I meant that I hoped that gutting my cats would reduce the sulfur smell I get at WOT.

change your o2 sensor. that might help.

Who me? Michigan stopped doing emissions tests a while back....

Yeah I am going to pretty soon, plus I have some MIL elimantors for the O2's after the cats.
