I run straight open headers with no x pipe or muffler, im selling the y pipe and dont have enought money yet to buy the x pipe and mufflers. so I still need to drive it but can i drive it like that with out any problems, or will i have problems with car later.

 

u can burn the 02's. When the fresh air hits the O2's it will thing u are running lean. It will add fuel and your MPG will go to hell.

 

how long will it take for them to burn out

 

i dont know. It could go in a day and it could go in a mouth. the reason the burn is not the fresh air it is the raw fuel that hits them.

 

other than that is it ok to to run with them open for about a week or two?

 

You want to run straight headers???? It will be loud as hell !!! COOOOOOLLLLLL :-)

 

dont know if it's true but i've always been told if you dont have enough backpressure you will **** your valves up from the backfiring. I doubt it would **** it up in a week though. I'm sure the lt1 will sound good though. I started my ls1 straight headers when i first put them on. It sounded like ***. My big block sounds way better, and louder.

 

it would be much better if you could get about a foot and a half of straight 3" tubing to slap on while you wait.

 

I concour. Im running open y-pipe right now, but my cars retired of DD. Not that its a race car, but because I dont wana rack too many miles up. I like it, but sooner or later im just gona install the I pipe to make the borla functional, lol.

 

O on the vavle part. It is not the back presure or anything like that. The vavles are at 500-600f easy. When cold air hits the hot vavles after u turn the car off it can crack the vavle.

 

hmmm loud, loud is awsome and as for valves wish me luck

 

Just be loud, being a 94 you only have two heated Oxygen sensors before the cat, nothing after the cat like a 96+ OBDII car would, how ever being 94 they are prolly crapped any way from age. The fesh air wont kill them and it wont hurt any thing, just be noisy.

 

hopefully i dont have any problems with police?

 

if you go by a muffler shop, just get them to give you like 2 pieces of 18" scrap 3" pipe and put them on the collectors. this should keep your O2's safer.

 

It'll draw some atention to you

 

Thats an understatement
