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

RXciting 04-01-2003 12:59 AM

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.

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.

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.
