Exhaust System

[Brandon.Nutter]

Im driving my 83 Mazda Rx7. It has a dual pipe header, which runs to a 2:1 pipe, which runs to a 1:2 muffler.
And that set up is quite loud. Of course i can drown it out with my radio, but i would still like to have some silence while driving. Does any one know of another way i can run my exhaust system to make it quieter?

Mazda Rotaries quiet?
no way.
just ask your dad.
I was right behind him one time going in to turn 1 at nelsons and he de-accelerated and backfired big time.
Scared the heck out of me, I thought my car blew up or something.
It was quite loud!:blink:

Just turn the radio up, you'll be fine :D

Two pipes all the way back. Two center presilencers and two mufflers in back.

This is not the best hp-wise, but it's pretty quiet even with straight-through mufflers.

Street car? Full Racing Beat system. Quietest system you're going to find outside of completely stock.

Greg, there's top secret switch we all install in our Rx-7's, it's called the 'Hey Back Off' switch:)

I think we have the dual silencer RB mid section sitting around somewhere, maybe at my dad's. I think at one time I even had the RB dual to one muffler, but I think I might have lost that while 'mowing the grass'

Thanks for everyone's input to my sons inquiries, I've been traveling alot for work and more people making suggestions really helps.

Now hopefully everyone will be as helpful when I finally get around to sorting my car out :)

BTW, I like your avatar but is that your brother in front?

[Brandon.Nutter]

No, don't you remember? that was one of the 10 year olds stomping us in the 50cc Karts...Because someone bought the wrong motors.
And the thing your talking about, the dual pipe, is at your fathers. I just need time to install it.

Scott - I havent given your son one bit of advice. I dont know a lot about RX-7's but I did learn a lot when we were at Nelson's a few weeks ago.
See what do I know, Im just one of those Honda guys....:D
