Exhaust Note - Mufflers & Pipe Size
An interesting topic sprung up recently on another forum, and it's got me thinking, so thought I'd pick all your brains on here.
I don't like my exhaust note when I hit the pedal quick. It's got a real 'bark' and can pop, and I'd describe it as a bit thongy/flappy in general. I prefer a more deeper, growly, bassy kinda note (without being excessively loud). I just hate how my can 'cackle'....
So what do you think? Do mufflers play the biggest part in the final note? Tailpipe sizes? Exhaust size? Fitment of, and/or placement of balance pipe? Other thoughts?
What systems and mufflers are you all using, and are you happy with the sound?
I've heard good things about Magnaflow mufflers...
FYI: My current exhaust system consists of Tri-Y extractors, 2.5" collectors, into a twin 2.5" system with twin straight-through mufflers (which have an intereference chamber in the middle), with twin 2.5" tailpipes. Also have a balance pipe fitted (although it's quite long and banana shaped where it was placed).... This is all on my 383 Chev V8.

I've got a twin 2" piping to a Genie Turbo muffler with twin dumpies (although they don't affect the sound) and it gives my car an awesome crisp rumble, although lots of people think my car is a V8 until i shatter their dreams and say it isn't, as its quite obvious it isn't.
I reckon if i went any bigger exhaust piping that what i currently have i will lose the good note i currently have.
I wouldn't go too far if it meant changing the sound of the car, only changing mufflers, unless the car really sounded shit

Brett I have heard you beast and Mate I personally think she sounds tough as, but I guess it is your car so you have to be happy with it.
The XY runs HPC coated Pacemaker 4 into 1's with a 3" collector, twin 3" system with balance pipe into offset Lukey Turbo Mufflers dumped from the mufflers before the diff. I also had a set of 2 1/2" tail pipes made up to go over the diff for road worthiness reasons.
I think she sounds sweet, the family next door doesn't.................

Hey Brett. My Hg has 4 into 1 pacemakers, 3" collectors and twin 3" pipes with mandrel bends. Before the diff I have two straight through 3" resinators, and after the diff a pair of triple flow mufflers. I forget what brand they are. No balance pipe.
I reckon It sounds pretty sweet, nice and deep. But that could be my lazy engine. But it is loud. too loud.

Just about to make my twin system up but the mufflers won't fit under the floor ! so whats peoples opinions on a twin 3 " with the 2 mufflers suspended off the back of the cab with dump pipes on the end of them, will need some good mounts I suppose as the pipes and hooker mufflers aint light !
anyone else used Hooker Aero Chamber mufflers before ?

My injected 355 in my WB is running pacemaker comp headers into twin hi flow berklee cats, then im using my same twin 2.5 inch press bent system that dumps behind the rear wheels.
I thought that it would sound completely different to what it did with the old 253. At idle it is very deep and nice, but up at a decent rev it still retains its BLAP. Im going to look at getting a balance pipe fitted first and if it still blaps alot I may change the whole "cat back" system again.

LXCHEV, I recken your car sounds great, a bit loud for the street maybe but nice. I'm running a twin 2.5in system with a Turbo muffler and a 10in hotdog each side. I'm not running a balance pipe because I like the sound without one better, a balance pipe tends to even out the note a bit and I like mine to have a bit of an uneven sound.THERE'S NO SUBSTITUTE FOR CUBIC INCHES........EXCEPT FOR RACE POWER!!

Hey, a dececnt resonator in each bank of pipes is what i would be doing, not hotdogs, it will make the note deeper and remover a fair bit of that "bark" when you mash it, it doesnt need to be huge or it will quieten it down too much.

on my ute i've got genie extractors into 2 1/4 pipes then a pair of turbo mufflers and twin 2 1/4 pipes to the back, i like the sound o this setup, not too loud but it gets a tad bit softer at high revs.
the vks got standard manifolds into 1 2 1/4 pipe into the muffler and a 2 1/2 exit pipe, this setup is way too soft, needs to be louder and more rumbly

I had a set of extractors on my old HZ (dunno wat brand, they were on it when i bought it), which i put a twin 2 1/4 inch system up to with one Lukey sports muffler on each side, and there was no crackling noises (except from the head lol) and it sounded neat as, but it also wasnt pushin out the HP figures yours would.:shoot rifle

A cousin of mine is also running a pair of hooker mufflers on his hq statesman. I pretty sure he's running hpc coated pacemakers 4into1 with twin 3in exhaust, hooker mufflers and no balance pipe. Car sounds awsome, not too loud at idle but when he boots her its lound! Mind you any v8 engine revving to 8000rpm will be hard to keep quietbiglol

Yea hookers don't quieten down the exhaust note that much, but they definately have a unique sound. Im running a twin 3" system, with resonators before the diff and a couple of straight through hookers at the rear. The sound level is just right and they do sound great
