how loud is a stock 12 with striaght pipes and a straight through muffler design possibly with a resignator in between
also the exauhst on it is original from 85 very rusty
my car was doing fine then one day the car wouldnt red line im thinking this means my exauhst is plugged cause it doesnt stutter or anything and my exauhst backpressure at 2500 feels like my dads subaru when its ideling

It will be really loud....Espically if you have a header. You really NEED a resonator, and a good muffler to keep the noise levels down. And make sure that you get a high quality muffler so that it doesnt burn up with the heat of the rotary engine.

I had a header into straight pipe into a burnt out glass-packed muffler, you don't want that trust me, get a good stainless and ceremic packed muffler. I had a friend of mine rev it for me when i was standing outside the car about 5ft from it, it was so loud it made my heart skip a beat and my ears to ring for the next 10 minutes afterwards.

anyone know how loud my car will be with a racing beat header straight back to a racing beat muffler?

dirty86

http://cgi.ebay.com/ebaymotors/ws/eB...category=33636 for a muffler how big pipping should i go?

or do i need a RB muffler

Sounds like a plan.

2" piping should be used.

Sounds like a fuel issue if you can't even redline the car..

Oh yeah and i'm running RB header/presilencer with NO muffler and its freakin' loud (but oh so sweet throttle response!)
I'm thinking of taking an n1 style muffler, cutting it apart, and re-packing it with steel wool..

Gregs

let us know how that goes, i might do something similar
nothing a sawzall and a wire feed cant handle

During the summer i tried repacking my muffler with stainless wool (it was fibreglass inside) made no difference AT ALL......

Chemical

What kind of muffler was it?

I'll have to try something a little less than straight-through then.

Gregs

it wont make a difference sound wise, but as far as life of the muffler is concerned
the SS will last longer

Should be decently quiet.

how would a 3" header into a edelbrock muffler do??

if it's a 3" pipe all the way back to a 3" edelbrock straight thru muffler, it'll be extremely loud; very little muffling would be going on.

a multi-chamber muffler will quiet it down more and add some restriction.

not to sound like a broken record but the racing beat header and dual presilencer into a 2.5" straight thru magnaflow muffler gave me very good power with reasonable sound muffling.

In a nutshell, I had that setup and had to lift when cop showed up; and there was a constant drone @ 80mph on the freeway. Some dynamat and a supertrapp end disc or pacessetter resonated dual exhaust tip woulda helped quiet it.

My setup consists of a RB header, 2-1/2" straight into a Hi-Flow Turbo II muffler (made by cherry bomb), then back to a 3.5" canon on the back. Without the silencer in its VERY loud! Outside AND inside. With the silencer in its drivable, but doesn't look as cool.

OMG you guys are hilarious. Get some steel wool, and hold a flame to it. That stuff frikin burns. If you want something to last more than 5 seconds dont use frikin steel wool. I do movie special FX and we use steel wool as a pyrotechnic. Using in a muffler straight up is a horrible idea... if you do it though video the tailpipe the first time you start it up. It will be hilarious.

wwilliam54

i think ill go with 2 moroso mufflers that directfreak had such good succes with

Lisa

I run an RB header to straight pipe to RB muffler - it's actually not that loud. People are surprised by how quiet it is.

I have a brand new RB presilencer, never put it on, if anyone's interested in buying it.

GavinJuice

Sounds like no-one runs the RB muffler. Is their muffler in particular pretty restrictive?

honegod

totally right.

but you DON'T use STAINLESS steel wool as pyrotechnics, because it doesn't burn for diddly, that is why it's stainless, no oxydisation.
