G'day all, I was wondering if anyone has any Suggestions or information regarding exhaust and mufflers set ups that make a Clevo sound good.
First off, its for a XC Falcon with a Mild 302 that still being built up so that's all I can tell you now engine wise.
The Funny thing is that all the Muffler shops I ring are telling me to stay well away from the Turbo, S pattern - Triple Flow type Mufflers, but heaps of the cars in my old car Mags have them on there exhausts so I cant figure out why they are all saying bad things about them?
I'm being told to go for a set of, complete straight through Mufflers twin pipes on a 2 1/4" System with one Balance Pipe.
If anyone has any ideas or tips please feel free to leave them or email me.
Also does anyone know what is was the GT HO mufflers were like? I have been told by some people that they were a straight through round shape muffler and others have said that they were a Triple Flow turbo type.
I don’t want it way over the top loud, but a nice firie Hot Rod note would be just what I'm after. I have been told that on a twin system using smaller pipe like a 2" with small straight through's will give a real firie crisp, live, note. Where going to 2.5" pipe in a twin will give a deeper note but lazier, sleeper, loose note. Anyone with experience with this please feel free to offer all you know. Thanks!
best thing for a good note is a cam with a lot of overlap!! but really.. whatever you do .. make sure its legal !!
For a stock or mild 302 I would not get straight through because of the noise..you will get a lot of droning if you aren't careful too.
I am happy with the XA but it's got a cam in it .. perhaps you should just go to a cruise that has XC fords (oranything withg a cleveland for that matter) and see what sounds the best and ask the owner.
"Dyno Max" make's a great muffler that sound's good, is free flowing, and doesn't cost an arm and a leg.
You might want to go larger on you pipe's, say 21/2 -3in. This will ensure free flowing exhaust.
Hopefully your using a good set of header's?
When in doubt :DON'T

that on a 302 with mild heads and mild cam, ment i wasn't making power above about 3000rpm (if that), awesome acceleration, but crap high up, not enough back pressure.
the new system, im told, will be better,
2 1\2" press bent
Triple flow mufflers
EVERYONE tells me that clevo's need backpressure, ive even seen 1\4 mile runs from guys that go from 3" mandrels to 2 1\2" press bent exhausts with X-Pipe that drop as much as 1 to 1.5 secs off their 1\4 miles times
it was absolute crap for power, it was so loud i used to set of house alarms, as i drive up the street, not to mention car alarms in car parks, yeesh. but like i care, it cost me nothing anyway :D
QLD Transport got me at 112dB @ 10m from a 45° angle from the rear of the car @ 4500rpm (like it would have made much difference to what angle he got me at on a dumped exhaust)
i just used the good old excuse "Must have a hole in the muffler mate" that coupled with the fake 4" tip out the back, they believed me, and gave me 14 days to change the exhaust, and report back to QLD transport for inspection, 3 days later , the 302 went bang, dropped a bigend bearing, hence the rebuild.
Moral of the story is that you CAN have an exhaust too big.
