I was doing a little maintenance on my cats last Sunday (lol) and started it up with just the manifold. The 3k start-up began and I had to shut it off...I can't imagine it with headers...

im off to the exhaust shop to piece some exhaust back together. bbl

hmm, so no one never tried open turbo.

I ran in CSP for a while with a resonator on the tail with custom header and bonez straight pipe only. I was usually the loudest car there and eventually was told to change it by some lame *** tech. The other loud car was a totally modded out midget and no one complained to him just because his car was in better condition than mine. Totaly biased against me. Oh well. I got many complaments about how the car sounded tougher than the other whiney metalic sounding rotaries out there. I also had header wrap and wrap on the bonez pipe. It helped deaden the metalic ringing sound of the rotary.

KEEP EM CRAZY LOUD!!!!!

PISTONS!! BOOYOW!

Yes, when we got kurgans 20B FC running, we ran open downpipe around the block at 4am.. It is not nearly as loud because of the turbo.. But it sounds SOOO damn mean..

i ran open rb road race header and yes it is insanely loud, but i kinda like it like that, the rumble that it makes sounds badass!

Sledgehammer on the forum took off his cats and just had his header on (atleast it was his cats or pipe - i don't remember his set up) and shot a video with just an open header exhaust. It sounded pretty neat, but was incredibly loud.

Turbo Timmy

This kid showed up at the track with just an open header, everyone was like oh crap that thing must be fast! It quickly turned into laughter as he ran a 16 something. He left his hood open while he was in the staging lanes and someone switched his plug wires around so that he couldn't run again LOL.

i ran my 87 t2 off the downpipe once and it was pretty damn loud

I love the sound, but it's too loud for the streets. In a couple of days, I run it open headers and get it on video. I'll run it at night so you can see the flames I can shoot out of it.

hmm so with open "downpipe" u hear the spool up louder? its not loud as a normally aspirated dual wankel? how much more "boost" will i receive with open "downpipe" also the "horsepower" of open "downpipe"?

What's open exhaust sound like on an RX-7?

That's what open exhaust sounds like on an RX-7.

I've never had a catalytic converter on any of my RX-7s

Gawd, this thread makes me want to run open headers around again. Too bad it gets too hot under the car and warps heatshields and melts the undercoating..

finally an easy way to get rid of that black build up! cheaper than having it sprayed off (with whatever they use; sand?? hell i dont know).

I have an rb uncollected header, and two spintech mufflers...and then a turn down on each...its not unbearably loud, but still VERY loud, and I love it...all 7000 rpms of it

xplikt

NICE! Do you have a clip of that exhaust setup? I would like to convert to Spintech true duals on my RX-7 and my pickup. Good mufflers, but I have no idea what a true dual Spintech would sound like on the 7.

xplikt

Also, where did you put the turn down? Back bumper or like under the car?

Nowhere

Hehehhe, you all are welcome

Nowhere

Hehehehhehehehhehe!

4k rpm! Anyone want the video with the FLAMES??

imloggedin

my exuast pipe broke off somewhere near the exaust manifold on the NA i had before.. it was so friggin loud it hurt my ears when i drove it around awhile.. and i have high tolerant bass ears. my friend said it sounded like an airplane going down the road lol

Sir Rupert Hobo

that first link isn't working for me either

I would like the vid with the flames. What's funny is any sound clips of the open headers are pretty much useless because it drowns the mic (any of ours anyway) after like 3K.

Why doesn't the first link work? Could be because the thread is 8 months old. Some dumbass resurrected it.

Anyway, here is a vid of interest I just took.
