So I've been searching posts all day and still can't seem to get a real answer from then.I couldent find a acual dyno tested header post or mabe I'm just not looking good enough.any help?I wanted to buy a alphawerks from the classifides.what do you guys think?I did find out about the anti fouler and I'm willing to do that.

 

A header is a header, it will make your exhaust raspy and give you top end power. Thats really all you need or want to know. So whats the problem?

 

heres the thread for dyno's:

Spicy so your saying a ebay header is just as good as a 500 dollar one? And thanks for that dyno 128 really helped

 

really not a huge difference, you essentially get what you paid for as far as build quality. they all provide marginal gains, and really, the rest is just for personal preference/aesthetics.

 

9k cool because I don't wana have any welds break on me or not have it fit right.u guys acually answerd my question!! How about resonators? Do they acually make the rasp go away?how much are they;for lack of not reaserching them myself

 

resonator will quiet ur car down a little bit but rasp will still be there. Always will be unless you don't use a header. that's just how it is.

 

Dezod is making a catted header, They said they tested it on a rav 4 and there was not sound change at all. They have not dyno results yet, but said they would be coming soon. Here is the link. https://www.scionlife.com/forums/sho...d.php?t=208835

 

Well I guess suped up honda sound it is! Cai ,header,axelback should provide a lot more flow for me.thanks for all the replies

 

Honda's will never sound "suped up" except for F20 motors, J motors, K motors, and some B motors. The rest of the Hondas will be farts.

 

A good resonator will cut out the rasp on a car. Heck for a cheap fix I had the longest cherry bomb glass pack I could find welded in my mid pipe and the rasp went away.

 

"hushpower" was the best for my set up. i've had megan and aero, wich both did not work for me. my set up is c.a.i., header, downpipe, midpipe, exhaust, no cats and tuned on ultimate.

 

Had hks exhaust and mmw header. The difference in performance was okay. But nothing to run home and tell your friends about. I decided to put my car back to stock. So trying to off load all my mods. List auto power roll cage, b@m short shifter, jic magic coilovers, ingals rear brace, unichip plug and play, monster motorwerks header with s pipe. Pm for prices and pics.
