I would like someone who is actually smart about cars (not some dumbass on the forum who knows nothing about motors to answer this question.)

I have berk hfcs and i want to know if taking off my hks high power exhaust at the y pipe could cause any damage to the motor?

I am only doing this for a day to shoot a drifting video for class and i love loud cars (but not when there my DD or else i would have got test pipes)

There will be a massive TQ loss that would happen and i am well aware of.

to me this doesn't seem like it would be that big of an issue due to the fact that the hks is practicly perfectly straight and has flow threw mufflers.

please correct me if i am wronge.

 

You'll be fine. Running it with no Headers would cause burnt valves.

 

Ive ran my Z w/o exhaust a few times due to emergency reasons... no probs at all...

 

same i have hks true dual + test pipes iv taken my mufflers off several time out of shear boredom and iv never had any issues. but like you i was curious if there might be any long term effects if i left it that way or did it on a continued basis?

 

At the worst you could possibly blow the o2 sensors.

 

+1. You should be fine. I have ran with manfold and test pipes before.

 

alright sweet guys thanks for the help. glad to see you all can tell me out of experience that i should be safe.

i'll let you know when the movie comes out in theaters
