Both from racing beat, would you notice much of a difference performance wise? or would the onyl drawback be having to keep that big boxy rusted excuse for a header in your engine bay?

 

this has been discussed plenty of times before, while i have no data to back up any claims it seems that yes the header will make a little more power but not enough to deal with the awful noise some header setups produce. the only way i'll ever put a header back on my car is if i get a borla muffler to act as a presilencer. the noise my car made was plain godawful and louder than any street car should ever be.

 

The iron box collector is designed to detune the sharp exhaust pulses & mellow the tone at the expense of a small power loss.

If you are evolving to a ported engine, the header helps even more.

The presilencer is a must, to keep the noise down.

A sound bite from my prior NA (full dual, header, silencers, bombs) >>MP3 stereo sound bite

 

ok thanks. Ill just stick with the stock header then, and get the downpipe and presilencer.

maybe ill sjut take out the header and sand it and buff it up a little

 

It totally depends on whether or not you're running a cat or presilencer and the sound quality of your mufflers. My RB header + stock main cat + RB catback is QUIET.

 

well for right now it will be all stock but downpipe and presilencer

 

You shouldn't be in such a hurry. Better to do things slowly and properly, which generally involves saving and budgeting. RB headers + Random Tech Cat (what I will replace my stock main cat with eventually) + a quality (read: not too loud) catback will be awesome sound and performance.

 

will it really be that bad for me to go half an half though? I know what I want to do, eventually it will be all racing beat, I jsut cant afford it at the moment so I figured Id go header/downpipe and presilencer, then y pipe and mufflers later
