Which will give a higher power gain, collected headers or uncollected headers?

true dual uncolected headers



twin pipe never crossing over..



go with the mazdatrix complete dual uncollected

the peak hp is about the same with collected vs uncollected, but uncollected have a better overall power band. Personally, I don't think it's worth all of the extra cash, plus that increased power will probably get overruled by the extra weight.

Just go with headers and straight pipes, much cheaper, and almost exactly the same acceleration.

ok, thanks !

I used to have the ture duals on my vert, but sold it to Isamu. It was a very nice power gain over stock. Great sound too.

yeah, if you liked your ears to bleed. https://www.nopistons.com/forums/pub...1047683473.gif

It couldnt have been any worse than no exhuast.

The exhaust kicks ass, but it definitely is loud as hell though. It has a nice deep sound too.

I have the duals and i love them. I have debated this many times on RX7club.com

The sound is not LOUD it is loud but it will not make your ears bleed the guy who said that is an

ass besides loud is not a quantitative statement a measurment in db would be more indicative of the loud ness. I love the sound but others feel differently.

Well when you don' t have the RB mufflers on there it is loud as hell, I know it was on my car. The guy who is "being an ass" is my buddy and has heard the car many times, and knows how loud it is. Maybe you should get a little more info before you start calling people an ass. So who's the ass now?

Go back to the "club" they seem to like assholes there.

Chill there buddy, calling sidewinder an Ass was NOT COOL. He was joking about the exhaust because its super freaking loud!

ok, how loud would an N.A be if : it had Headers... and that's it. No pre silencer, no mufflers..



Just headers with a pipe running out to the side of the car.



Would there be any power gains from running open headers?



And how freaking loud would it be?



I'm even thinking about taking my radio out. so Noise or hearing things really isnt an issue.



Thanks guys.

It would not be streetable, it would be too loud. You would get pulled over just being at idle. So if you do it, I hope you like cops, because you'll be dealing with them alot. As far as power gains... I think the power gained wouldn't be worth going deaf.

if you run a header and let it out the side, it will be as if you have no exhaust on whatsoever

i had that, but it gets tired fast as you cant drive it for more than one hour as the sound makes

you loose all sence of soroundings, TOO loud trust me , i like loud but thats overkill

Man, too loud??? I'm gunna try it, to see how it is. See if i go deaf! https://www.nopistons.com/forums/pub...DIR#>/ohmy.png





Lol, like i said, i'm gunna try it to see.... thanks guys
