Good to run straight headers?

[mdchaser]

I just got my pacesetter headers today and I want to get them installed soon. Since I'm going to bolt Tiagos turbo up to the headers is it alright if I dump straight out of the headers for a while? I've heard this can cause problems with the engine?

[BLLDOGG]

sorry, this is kind of off topic but how are you going to hook his kit up to the headers? his kit is designed for stock preferably 00'+ last i heard

[mdchaser]

Well I'm not exactly sure. Tiago said it's gonna take some modification one way or another and that it shouldn't be a big problem... Thats why I want to run open headers, I'm not sure how the turbo is going to bolt up to it...

[skorpion317]

you can do it, i don't think the local authorities will like it though.

I did it for about a week. It is pretty loud. Don't drive in your neighborhood at 2AM.

[viper98885]

Yeah, it's definitely gonna be loud. You can hook up the turbo to your headers with some custom piping. Let Tiago know what you are doing...he'll take care of you. He's a good guy and knows what he's doing.

Yeah, it uber loud. I think its louder than a chopper bike, IMO. I actually got a thumb up from a biker with a harley when I ran it open headers to the muffler shop.

So it won't cause damage? I thought the engine needed some sort of backpressure???

[majeskyb]

I think the most you'll do with open headers is lose some low-end torque. The most damage I'd worry about might be extra heat in the engine bay, but then again, I haven't done it. Maybe put the y-pipe on to move the exhaust away from the engine a little bit?

Haha just don't run by any semis at WOT on the highway... the sound bounces off them soo much and is sooo freakin loud. I ran mine for about a week till I could get the exhaust worked, and that was enough. Definately loud, but sounded mean at idle

[RallyRed 98]

"lack" of backpressure isn't going to hurt... i guess you mean running through an open y, which is fine.

running open shorty headers is probably a bad idea, because when everything gets heated up, if you shut the car down and get a blast of cold air or even water up through the primaries, you run the chance of cooling your valves, etc. too quickly which will misshape them.

[Dominic]

you can crack a valve... dont do it.

[99v6cam]

Yeah, I've heard alot about people floating thier valves doing that. I wouldn't do it, at least not for a long duration...
