The key to a good exhaust note...

Hey all
Im looking at getting the exhaust done on my celica (st162) within the next week. I currently have the 3SGE motor in my car and a set of genie extractors. This is basically the only modification to the motor, and i would be looking at changing the air filter and induction soon, to a pod style filter with a heatshield and some piping run for better induction.
I was wondering, bearing all the above in mind what sort of exhaust i should go for, im looking for a good deep type tone. I dont want a raspy drone. so obviously i will need a resignator in there to eliminate that. I want a cannon style muffler, can anyone tell me what else i will need. Obviously you can not give an exact sound example. But i really am trying to avoid a droning system, or a tinny raspy system.
What size piping can you guys reccomend etc, does what i have mentioned above sound good ?

Cannon is also known as the farting pipe and Milo tins ...
Have an exhaust note that you are happy with, not too a huge drone that you can't hear yourself think at any engine speed...
Cheers.

Hi,
Run extractors from the engine and into a 2 to 2.5inch pipe. Near the back of the car put in a smallis 12 inch muffler - not a baby-size hot-dog style, but not a large one muffler, then about 6inches of pipe to the rear. Sounds perfect on an 18RG - nice deepish sound, no raspishness, no drones but has a good distinctive, untinny sound.
Certainly sounds better than some 4cyls and certainly better than a rotary (which always sound shit to me).

if you want your engine to sound like a WRX u can get extractors with primarys that join cylinders 1 with 2 and 3 with 4.
Great for their low efficiency and f00ly sik WRX sound.
im sure genie know better than this so u can ignore my

well, you already know what you want. i'm a fan of resonators (i have two in mine  , along with a large chambered reverse flow muffler which makes things very quiet at 8000rpm)
from my observations, the only cars that sound good with cannon style mufflers are turbo cars. reason being that the turbo chops up the exhaust and you lose a lot of the pulsation that you get with an NA car. ie the turbo restricts the exhaust, so you can have a milo tin muffler and still sound ok.
with your NA car, the milo tin will amplify the exhaust noise (imho) and sound... well..
in my opinion, the best sounding exhaust is one you don't notice. a resonator and then a large chambered muffler, preferably not 'straight thru/turbo' style, will flow well (if you pick a good size), not be loud, and because of the large chamber, will still have a deep tone...
but if you want a cannon, by all means just get one  it's not like it's an expensive decision anyway, so you can afford to try a few different ones.. (oh and get one that is well made, not just expensive/pretty)

If I do say so myself, my 2T is the best sounding 4 I've ever heard. 4-2-1 Pacemakers, 2" straight through with a resonator and baffle-less muffler. Has a big cam though which helps to no end. I get positive comments from everyone, even non-car oriented people...
Though it is 116+db at idle

My 2TG sounds good. 4 into 1 Genie extractors, 2" all the way. 2" glasspack hotdog style resonator after the extractors. 2" glasspack muffler up the back, dogleg style (offset pipes), with a open chamber in the middle of the muffler.

as you can see, some people prefer to have a loud, but 'nice' sounding exhaust, while others prefer to have the intake noise louder than the exhaust...
just stick something in and if you don't like it... change it.. simple

I love the exhaust on my sprinter.
Kellam 4-1s, followed by pipe.... and lots of pipe.... through to more pipe... a few flanges.... and more pipe..... oh yeah and air.
Still somehow the quads manage to be louder.
I have various mufflers for it depending on circumstance, but when im racing its normally free flow. Although sometimes i have to muffle it for noise restrictions at certain tracks.
Toying with the idea of ending it with a hotdog glass pack res i have lying around. Probably wont do much, but ill just get a new "end" from the flange back made up with it.

is yours a manual? manuals tend to be a bit deeper. my bros telstar has extractors, 2 inch exhaust all in mild steel with a standard muffler, resinator and sounds deeper thats all. when the engines warm it sounds a little lumpy.
my supra has extractors a hot dog resinator and standard muffler and it also is deep without being loud.
i'm a fan of quieter exhausts especially cause i'd rather listen to music.
a canon muffler will just make the exhaust note louder. i say if you want it get it, they do look better i must admit.

Okay dude, best thing for our cars are as follows:
1)Genie extractors or something similar, which you already have
2)High-flow cat if you want(these are expensive and not always an upgrade) though given the age of the car its probs still original so it might be effed, you can weld in some straight pipe if you want but i warn you its not legal
3)2.25" piping from cat back with a resonator midway(hotdog style) and a glass-packed muff with tip on the end.(get mandrel bend if possible!!!!)
with this setup it is reasonably quiet at idle(not much louder than stock) but when i give it stick it opens up very nicely.Not barky,not raspy but i reckon spot on.Im also under legal limit at about 80dB-85dB if done properly.
I've gone for a twin tip as it looks cool(i reckon) but if you get the muff with an option for different tips go that, cos if you dont like or get sick of one, cut it off and weld a new one onto the muff.
goodluck mate

my sprinter has:
RWD factory exhaust manifold, factory secondaries.
2 inch press bent over diff, with a lukey open centre offset in centre out muffler, not sure what size, i'd say "medium"
i really like it, sounds fantastic at idle, but it has this annoying rasp kinda note at about 4000 rpm which i dont like.
i dont think fitting a resonator will fix this, will have to see after i replace all the bends with those of the mandrel variety.
i think it is legal too, have to measure it one day.

I want/& need to get a new system on my 86 when I have the funds... and hopefully I will get it sounding really nice...
at the moment it has the standard headers, going into the old ass cat... with standard pipe to a 3" supercat cannon with 4.5" tip....... very loud... definately defect worthy..(have been done for it before but got a silencer made and passed it)...
I plan to get a new system comprising of extractors..(what ever I get my hands on)..2.25-2.5" mandrel bent piping with a high-flow cat...a resonator of some descrition and finish with a smaller cannon.
I will have to see how this sounds..... I want it be as free flowing as possible but not to loud..so comprimises have to be made. It will be for a 4age... and Im going to make it so it will be suitible to use when I do a 4agze swap.

N/A if you want to keep it legal you really need a resonator.
With a turbo you can getaway sans-resonator.
I have a 3inch mandrel bent system with a single cannon on my 4agte, and it's quieter than the GZE was with a 2.5 inch system, conventional muffler AND resonator. Albeit a lower tone.
