running with no cat, whos doing it?

[sonicnofadz]

Ok, I know at least a couple of guys on here don't run catalytic converters on there dsms (and they are their main rides too). Is this actually common practice among the dsm community ? Everyone knows there is definitely some horse power gains in doing this, but exactly how easy is it to get caught running without a cat, and what happens if you DO get caught? If you run without a cat, will your exhaust become defeaning? I would like some opinions on if this is a good idea or not for somone's daily ride (especially from those in this forum who actually have daily ride dsms with NO cat).

I dont have the link, but there is a company that makes exhaust "cutouts". Normally your exhaust flows through your cat, but with this system you just flip a switch or whatever and your exhaust piping opens up before your cat.

i believe you're thinking of Q-tech, not sure of their website, but i'm pretty sure that's the company name.

i dont know a dsm'er in real life that runs a cat...The only place I wouldnt run w/o a cat is in cali.

if you got electric cutouts, you could just open them whenever and have open exhaust or whatever its called, right?
i know itll be loud, i know someone who has an 11 second mustang who has them, but what would it sound like on a DSM? would it sound sh!tty or not? dont think ive ever heard cutouts on a 4 cylinder.

also, what kind of gains should i expect to see with the cutouts open?

where do the cutouts go? one page i saw said they welded put them on a test pipe, you can have them without a test pipe right? if so, where would it go? i really dont know much about this as you can probably see.

Your wallet will be significantly lighter if you put a cutout-equipped vehicle on the public roads in the US.

if i got an apexi n1 downpipe, would it be worth it to get a cutout or not?

Im running the apex-i downpipe with n1 exhaust, its perfect and I love it! Why get cuttouts? Too much hassle, get the apex-i downpipe you will feel the difference and wont feel or see the need to get cuttouts. And I was wondering myself if they do smog tests here in Texas, my inspection was due in September. Its already January!!!

 

[x628x]

im thinkin they do but im really not sure.
last year, well i guess two years ago, my inspection was like 6 months overdue in my BMW. i guess the cops dont really check that when they run your plates, or they just dont care.

where in tx are you from?

 

[rivet0r]

I just got done putting my stock exhaust back on this morning. I was running just a downpipe, hell of a lot of fun compared to the stock piping. After awhile it got annoying, being so loud and all.. now my car sounds like a damn geo metro.

yea where I am there is no emission testing but still people check under your car for the cat though but hey I inspect car for a living so I ain't complaining

they dont check under the car for a cat here, atleast they didnt use a lift. maybe they only do it if theres certain smog numbers that would make them think there isnt a cat on. i dunno.

i once went to a muffler shop and they told me if you get caught without a cat you can get fine up to 1,000 dollars and now you can get ur car towed. this is in cali
but im not sure...

I've run without a cat for 2 years here in Alabama! Hell, a noted muffler shop even made it for me! When I roll up on the cops at a light they just throttle out right along with me! Gotta love no emissions testing down here... not to mention that Bama is the home of the monster truck! Driving WITH a cat is a ticketable offense. :laugh:
