How much hp do catalytic converters rob??

smttysmth02gt · Jul 2, 2004

I believe it's like 15-20 hp...

I have an o/r h pipe and trust me, you'll notice not only a new killer sound, but a little gain in power as well.

stock 6 cat H-pipes suck, but if you have an X or H with 2 hi-flow cats, there isnt much difference at all ....slightly quieter and slightly more restrictive, but not by far - maybe a few horses ...hiflow cats are built good. So if you live in a place that requires emission, just get 2 hi flows and you wont be sacraficing much and still pass the test

thanks hey do you know what increase there is if i put 3.73's in over the stock 2.73's in the quarter mile?

I agree. BUT, luckily for me, AL doesn't have emissions testing and I can keep my o/r h pipe on my baby!

What yr mustang do you have? 99+'s have stock 3.27's...

your 1/4 will be better with the 3.73s, but not by much. I mean afterall, its just torque you got ....same HP as before ...Definetly feels like a big boost though over stock ..but don't think it shaves seconds off your time or anything like that

NewStangNewbee · Jul 2, 2004

but if you get better torque in every gear how cant it shave a second or more off?

3.73's would help...but you need more power. W/that yr motor, the FIRST thing I'd do is get a head swap if you haven't already done so. Those heads suck pretty bad on the 96-98's. Find an old wrecked 99+ at a junkyard and grab the heads off of it.

Because in order for the gears to work, you have to be able to make a certain amount of power...that of which, you aren't making.

???? ok your the man whatever you say i dont really know i am 17 and thats y i ask.

Steve777 · Jul 2, 2004

yeah ...mines a 96 ..and i would like new heads too ...but untill then, oh well she's still fun

btw i might try out out some 3.90s

NewStangNewbee · Jul 2, 2004

do u know of a quarter mile calculator that figures in rear end to because i dont understand how they can calculate your quarter mile without it some how they do though

Steve777 · Jul 2, 2004

not sure

is yours stock except for the 3.73s?

It's all speculation in the first place.

Secondly, it is SOLEY dependent on DRIVER. If you suck at driving, you'll have a crappy 1/4 mi. time. Simple as that. I'd worry about performance parts for your car, and proper driving, then worry about 1/4 times. I'd guesstimate you'd get a 15 sec. 1/4 w/pretty good driving.

NewStangNewbee · Jul 2, 2004

yeah i am sort of weighing through what i should do next. I know i am taking of the catalytics so i think i will put headers on and while i am doing that i might do a head swap. I want to do it all at the same time so it is easier.

NewStangNewbee · Jul 2, 2004

i have an auto smitty so i basically cant suck and i would do better cuz i can go like 500 pass redline

Headers and midpipe will be easy at the same time. The heads really won't matter, as they are under the hood, not under the car like the exhaust.

Steve777 · Jul 2, 2004

If you get rid of the cats and get headers, get an X pipe ...you won't regret it ...long tubes, x-pipe and flowmasters sound so bad ass
