it goes back to the cat converter...the cat is still there but nothing behind that

You will be ok, just don't do it for days. But yeah will be hella loud

if you don't have a cat it will damage your engine ! if you live in US so it's fine not for long ( because you have a cat on !)

and don't stay in one spot while the car is running too long, the exhaust will leak up into your car and it'll stink bad. other than that, you'll be fine. :)

cool thanks alot you guys

how can running no exaust hurt the engine?

[ACCORD EX]

back pressure hurts the engine, doesn't it ! i mean the exhause prevents air ( outside) to go into the engine carrying all the exhaust shit ! :)

Thats not it, The time it takes for the exaust to travel all through the exaust system, allows the exaust to become cool. If you take the exaust off at the cat, it wont travel as much, and another thing....a catalayic converter is designed to burn the exess gas, so wouldnt that be a total fire hazard? I remember a guy put a cat converter on a V4 Engine that went to some tractor, we pulled the engine out and started it up to service it, all of a suden there was a 10 foot flame commin out of the Cat. I've heard it alot in here that Back Preasure is good for these low powered A20A engines, thats why its so popular for us to use real mufflers instead of the Farter Pipes (Glass Packs) that alot of people use now days like I made a mistake on when I bought my 3A Racing Muffler (Glass Pack)

running without exhaust isn't going to hurt your car unless you're creating a dangerous situation like blowing hot exhaust at your gas tank or something :ego:

my DX has no "axle back" part. LOL its loud as hell! BTW im just to cheap to put $$ into it.

[Neuspeed87lx]

i was talkin about my civic not my 3g but it dont matter ne more because i have an exhaust on it now ....i got custom piping from the local muffler shop 2 1/4 obvously and its welded to a dtm dual tip muffler...it sounds great ...real deap....not that annoying whine sound....it is quite loud though ....oh well i looove it ....

[Bullfrog]

driving with no exaust is not fun at all.....do you relize how loud our cars are!!!..wow defining....i hated it whne i replaced my flex pipe

[anchovies]

more back pressure == bad
less back pressure == good

turbo with open exhaust == bad-fukkin-ass :super:
