adverse effects of running open manifolds?

[shenanigans]

just curious what your thoughs are on running open manifolds for a week or two?

'00 with no y-pipe.


not worried about post cat o2. but each bank o2, they kind of worry me, think they might get some unmetered air backflowed in?

will I die from carbonmonoxide?

do I have to worry about underhood temps.


just considering doing something with the exhaust while its off but I would have to order some parts and wait.

hehe I am sure it will be... I once drove 3 hours with an open y-pipe on the 3.4L

It likely won't be my only vehicle at the time but I wanna put some miles on it.

i wouldnt do it without the ypipe on it, ever heard of burnt valves? i dunno if it would or not but i wouldnt want to risk it, plus you'd tire of the noise in the first day or two

I had headers for a lil while after I installed the headers. It was so loud and sounded sweet. Everyone thought that it had a monster V8 in it.

I ran open headers on my formula to the exhaust shop to weld my exhaust and i didnt take it above 2500 rpms to loud! i had it in 5th gear at like 30 to keep it at 1k lol.

Just don't romp on it all the time and you'll be fine.

It won't hurt anything.
