need some info

ok i have a 02 gt with fllowmaster 40s. im thinking about taking the cats off but i dont know how load it will make it. and dont know if it will help opening it up.

so what do u all think. and what would be the pros and cons about doing this..

stock motor, Flowmaster 40's & O/R H pipe

she sounds good.
so if i was to take the cats off would it open her up much. Would it help gane alittle bit of power. would it hurt the eng at anyway.

See im new to the hole mustang thing. ive only had her for 2 years now. before i got the mustang i did not know anything about it. i know somthings just not alot.
so any info would help me out alot..
Thanks..

I did the same thing boss. O/R H, flowmaster 40's and now I'm dealing with the whole school bus exhaust smell (see thread "Exhaust Fumes"). Make sure you can get a tune done shortly after removing the cats. Also if you have emissions testing in your state then you will not pass without the cats. It definitely sounds better though!

I never got a tune after my first O/R H install and never had that issue. I'm willing to bet you have a combination of bad rings and dirty injectors.

When you get rid of the Cat's it does typically run a little rich but thats about it.... I bought my car with the O/R H pipe 3 years ago and its never been tuned and the only problem i have ran into is the rich smell. You don't really smell it while driving just if i'm parked on the side of the street talking to someone they have to smell it LOL.

take the cats Off you have to worry about tickets because its loud. But if you are like my guys you will take the risk.I have x pipes and left the cats on .I dont want tickets .The law here dont like the loud pipes. but mine still sounds good.

Huh?

Well let me ask u guys this.
What is a O/R H pipe anyways?
woint with the car smelling or running rich make the rings go bad. i dont want to hurt the eng by doing this.
I know i dont want to make it way loud. all i have done with it is added a coldair and put the flowmaster 40s on. i want a deap sound and some pickup

An off road midpipe is a H,X, or Prochamber that has no Cats. There intended purpose is for cars that will not be driven on public roads. But the people that make them no that they will be used on roads.
And I would be very very surprised if there was ever an engine that blew because of a mid-pipe being added

hmmm....

look take the cats out and build you some $5 mil eliminators stick a o/r pipe perferrably a prochamber(best sounding) or any other x/h pipe and be done with it you cant go wrong youll love it it will start to sound like a american muscle car rather a beefy volvo if you need help building the mil eliminators gimmie a shout ill help ya there easy look bro i got an 02 vert with a prochamber and 40s no cats and everytime i pull up to a meet or show i got 20 people surronding me asking about the exhaust before i even get parked its sick unless you love the sound of a sissyfied car do it ..and no it aint gonna hurt your car at all without the mil eliminators your car will have a check engine light and run rich because the cats are gone but with the mils elims in it will turn the light off and make the car run properly like i said you can build mils for like $5 and ill help you just need to reuse the old o2 sensors lemme know ..........!!

It's always the tedious & small stuff that add up when building these cars. Last winter, I had a budget of $8k and by the time all the small stuff and "Oh Sh*t" things were done, I had almost $9,500. It sounds like you're more of a looks guy anyway; If I were you, I'd just collect random parts as you can find them used or great deals, then after you have a tb/plen, H or X pipe & mufflers spend $100 for a mail order tune and install them all at once.

That way you get the most out of the parts and you can account for all the small crap that's going to affect your tune. Those parts should net you about 250rw with a good tune.

anyone who knows me can attest to this!!! im in the same boat here planed on spending "x" and ended up with "XX" funny how that happens! i dont regret any of it but it sure was a long road.

Clarksville has Marta testing, right? If they do, they will check for Cats when you have the car inspected and if you don't have them, you fail! lol

Otherwise, do an O/R H pipe. It will open up the exhaust and won't have the crackle-pop of an X-pipe, especially with Flowmasters.

IMO here is the ultimate combo for sound and keeping your ride street legal...

Magnaflow High Flow Tru-X w/ high flow cats
Magnaflow Magnapack system

This setup is just right on ears and on the CARB settings.

I just put an off road H on my 03, LOVE it! Sounds like a beast and the acceleration seems a lot more smooth. Has the classic muscle sound, not to loud, but deffinately turns heads... I paid $40 for mils. No bad smells, a slight gassy smell at an idle, but nothing bad. I have a plug in tunner, but that was already installed before I did the pipe,,,,
