FAQ: The Exhaust Thread

I'm looking on Rockauto and I see a FEL-PRO "pipe to manifold" gasket. I also see a crossover pipe gasket, which I was going to change at the same time I did my exhaust manifold gaskets. Is this "pipe to manifold" gasket for the downpipe to rear exhaust manifold?

That would make sense to me....

Welp, a year or so later I dumped the glasspacks. They were just getting to be too loud. I put the stocks back on for now, but that might change later.

A dude in Cleveland made this for my bike from a design I gave him. Planning on installing early April with some other carburetor mods.
His son took these awesome pics. I am really happy with the results. No further updates on Riv exhaust...

I dont watch that show, cant even name it to be honest, but I have bowled a few times and I know X X X is an awesome score. Thanks, AA!

I think you've got dead links man

Ok, I think theyre good now..

er, Charlie, what do you ride? Hard to picture anything other than those pipes floating around making brappp noises.

Just tossing some ideas around here....

What do you guys think a Flowmaster Hushpower 2 would sound like on the Riv? It certainly quiets down big block V8's.....I watched tons of videos last night, just searching for that sound. Unfortunately, every moron with a Grand Prix just makes it loud, raspy, and stupid. I've used 2 different DynoMax setups, tried Thrush Super Turbos (yuck), and I currently have Hooker Aerochambers with a Pypes M80 resonator. I like the sound I have now, but I want "different".

Thoughts? (this may be beating a dead horse)

Have you tried the Dynomax vts? I'm still happy with mine. Only thing is I used aluminized steel for the mandrel bends and its disintegrated. Got some nice 16 gauge stainless bends ordered to re do it with. Also this time I'm going to try out adding J pipes to tune out drone @ 2000rpm. Math says 34 inches should be perfect, but I'll make it adjustable. Its amazing what Solo has done with the J pipes on the Pontiac G8, since it wants to drone and buzz like crazy when the AFM kicks in and it drops to 4 cyl. I'll probably at least have some fun pics in a week or so.

I have not. I wasn't impressed with the first 2 DynoMax setups. These Aerochambers do a real good job with the drone. They're designed to be quiet in the cabin during cruising, much like the VTS. They're also the only setup I've tried that's gotten rid of the backfiring and crackling once you let off the throttle. Well, every now and again, it'll load up (you can hear it coming) and go pop POP. It's actually kinda cool when it does it. However, even with 2 mufflers and a resonator, it still goes AAAAHHHHHRRRRGGGGHHHHH when you romp the throttle. I'm not so sure I want this much noise on the next setup.

A dude down in Toledo is running the slp power flo mufflers on his gtp, and I think it sounds good. It's full bodied and smooth without being too loud or droney.

What's wrong with stock mufflers? Mine sounds pretty quiet and no drone.

Right, but it still sounds like a fuggin 3800. I want "different". Maybe I'll just have my exhaust guy play with a few configurations. I was contemplating doing a single exit on the pass-side (like the Turtle), except maybe running all the way around the spare tire well before it exits....to add more length. The Flowmaster HP2's are 18" long and roundish. I should be able to put it in the tunnel, and only have pipe after that. Who knows....there isn't a single engine out there to compare it too.

EDIT for chuck: I don't want stock.

hmm, those HP2s are an interesting design...

I'll just leave this here....

That sounds sick. I like it....

If you can manage to find something comparable to them, or at least find them a a good price please let us all know.

I have the P/N's of the muffs.

"Center" muff is STR120.
Rear muff is STR124.

If you go to Redback website http://redbackperformance.com.au/ , you can look at the different kits for Aussie V6 cars. They are all RWD. However, the complete kit lists the P/N's of each individual piece. I looked through the "universal" muffler catalog, and the P/N's for those particular mufflers don't show up. I might just give them a call.

VX, extractors... must be holden.  The difference you hear is equal length primaries,  the 3800 actually sounds good with the engine mounted the right way around.  You won't get the same sound with just the mufflers.


edit:
also if you are cross referencing aussie stuff remember:
their Series 1 is our LN3
Their Series 2 is our series 1
Their Ecotec is our series 2

I was able to find all of that awhile ago too, but the only places I could find them cost way to much to ship. Not to mention the long distance charges of a call to the Aussies...

I hear ya on the shipping. They do have a toll-free line though.

Salesman here with the GTO ordered the Aussie Intake kit for his ride. The kit was $500. It cost him $250 extra to ship it all here.

Thanks Karma. I was aware of that, but I'm sure others are not.

I'm seriously thinking that the Hushpower will sound pretty good if done right.

Nice find. Never knew the V-6 Commodore sounded like that!

More awesome:



Pretty cool that our Aussie friends across the pond are tinkering with L67s just like we are!
