Would a cut out give me the same hp gain as a catback ?

If a cut out would give me the same hp gain as a catback then I'll go with the cut out. So does it ? If so whats the best bang for the buck I can get ? A link would be great ! I wanna know the pros and cons of a electric vs. non. Most important does a cut out sound like Ars or do they sound pretty good. Maybe a sound clip ? Thanx fellaz

horsepower... cut out will probably outflow a cat-back, however, i have heard that the magnaflow cat-back has a .5 horsepower disadvantage over the cut-out. i would get a cutout if you cannot afford a good cat-back system... as far as electric or not, i would get an elcetric one without a doubt, 70 more bucks well spent in my opinion, getting out to take of scortching hot wing nuts isnt my idea of fun when i wanna make it loud, rather flip a switch, and as far as sounds check out this site, they should have something....

simple physics says that a cutout will outflow a catback. now how much, meaning how much power you'll gain will depend greatly on the type of cat back...on a more restictive muffler you'll gain more, but you'll gain almost nothing with something like a LoudMouth.

if you just install a cutout on the stock 2.75" exhaust you'll probably gain about as much as a good flowing catback system. this is because you'll be keeping the 2.75" pipe, where a catback would give you 3" pipe.

electric vs non:
pros of electric are simplicity to open, flip of a switch
cons are price, $150+ and some have problems with the motors going bad and them leaking

pros of non are simple and cheap
cons are you have to crawl under the car to cap/uncap it which isn't something you can do at a stoplight

cutout will certainly outflow a catback. Only thing with the electric cutout is you have to watch out for burned out motors or maybe not closing all the way.

How common is a burned out motor ? How common are they to leak ? If I do go with a electric wich would be the best one ?

The first gen of e-cutouts seemed to have problems both on Qtp and Mccord units. I have held off buying the electronic one for now, and and happy with my cutout. 26 bucks from summit, 50 bucks for the install.

The car sounds so mean ... hehehe not to mention the look you get from people who are used to your car running quietly. Easily the best mod I have ever put out on any of my rides.

It seems like if you like loud you like loud. If your car has not been altered it should be easy to crawl under and stick the cap back on. $100 bucks is not worth the 3 minutes you'll save plus there is less that could go wrong with it !

I have a Loudmouth and SLP Ypipe which is basically a cutout with more piping. Some people dont like the cutout because it makes all sorts of noise right underneath the car. The main reason i got my catback is so the sound goes out the back of the car rather than under the passenger seat.

Depends on the size of the catback. You can get a 4" mufflex catback. You can't tell me a 3" cut-out flows more than a 4" pipe. In this case the restriction would be the stock Y pipe and cats.

How does a borla catback compare to a cutout? Remember one pipe is a straight pipe.

borla basically IS a cutout...albeit an expensive one...

and for the mufflex...i know they make 3.5" cutouts...probably somebody makes or "could" make a 4" cutout...how badass would that be...

a 4" catback with a cutout...

electric cutout

i bought the quick time performance e-cutout and have had it for 8 months now, no motor burnouts. you have to listen for it to get quiet again, it will leak, reopen it, reclose it, and it will seal in a few seconds. burnouts caused by stupidity mostly. gate stops but motor doesnt, so let off the switch. it does flow better than cat back with a nice rumble that makes mustang owners jealous. can take it a step more and gut the cats. wrong; yes, need sims; yes. but flows much better and ungodly loud. you get everyones attention. i assume you are going to have it installed after the cat? cant seem to fit it any other way. electric is the way to go, beats climbling under the car, and can shut it from inside to avoid the cops.

I heard that loudmouth can allow up to 25 horses to be gained. As per the website. But i would assume that is with like long tube headers. I am thinking of gettin loudmouth, i was toyin with the idea of a cut out and i would only get an electric one, but i would worry about how the snow, rain salt and slush are on the motor and joints that have to move? Catback can be just as good as a cutout, if the pipes do not turn around and go in circles. The longer and straiter the pipe the less back pressure and the exhaust is allowed to flow better.

Ya, you always have to look at the perimeters of any test that claims MAX HP #'s.
