Finally got my 6 dollar baffle from china (5 weeks) but ended up not using it . so it turned out to be a 10 cent muffler mod ! ... $ Hacksaw blade usage plus some rat tail file wear and paint .
.
If i didn't need a after market pipe for ground clearance issues i would be quite happy with this mod.
.
With the stock muffler the exhaust gos into the back chamber #1 and through a cross-tube into chamber #2 then thru another cross-tube into chamber #3 then out the final tube.

so I removed the final tube from chamber #1 and inserted the 1" baffle .so now the exhaust is coming out of chamber #1 for the most part and doesn't have to go through #2 and #3 , but chambers #2 and #3 are still open with the cross-tubes which could also account for the deep tone it puts out now.
.
the final tube is not welded at the mid baffle plates , which was a leap of faith i took from the video and sketch i found on you tube (below). It pulled out with a little persuasion , do not let it go back inside or you gonna have one heck of a rattle , pre-load a sharp end set of channel lock pliers in the pipe towards the tire, and tap it out with a hammer .it is snug , but it only took me 5 or 6 hits !
.
The new sound has about a 20 pre-cent loader sound and a great little deep tone to it.
so great for those just wanting to hide the sewing machine sound .and add a little Va-Room
.
But i also tried it without the baffle with just the 1" hole wide open and no baffle at all, (pic 6 ) and it has about a 40 percent loader sound and a deep tone to it . so going with that set-up myself
.
Guess you try even a bigger hole if you looking for 100 per-cent loader pipe like the after market ones , but that may or may not work ?
.
Most of all : It is not a cheesy, lawnmower, want-a-be real pipe sound at all.

Both ways it is a good deep tone just like a 400 dollar pipe / for 10 cents :D

Sound video ... this is without the 1" baffel ( pic 6 )
.
https://flic.kr/p/Fjyzhp
.
And maybe its more like 50 to 60 percent louder than stock :confused:
Vs a aftermarket pipe being 100 percent .
.
Also no engine light .and it is still probably a legal pipe because its still going through the cat's ..and has DOT stamped on the pipe (Ca. law)
.
A totally free mod that sounds like a 400 dollar pipe . or close enough :D

Did you just cut the stock tip off and remove the baffle that is there? Seems like something I will have to do before I get a real exhaust.

anyone try this with a airbox removal using a straight pipe to filter like K&N or whatever brand you prefer. do you need a fuel controller like powercommander or bazazz? im going to do airbox delete very soon and dont know if i want to spend a couple hundred more just for the sound.

I was going to weld the baffle in at first just so it looked clean and stock , but i need a aftermarket pipe for ground clearance issues . so just running it as is
.
I also had a 1 1/2" sleeve ready in case the 1" baffle wasn't the sound I wanted , It would probably sound even a little better and louder if some was to try that .:confused:
.
but the 1" is plenty loud enough for me ...
.
1 1/2" ID X 1 1/2" OD muffler sleeve from pep boys auto center
and it would weld in nice and look factory .

Kaw'ee Great Job! You think about rewelding the exhaust tip back on?
I ended up doing it this last weekend, the sound is just a bit louder than stock and nowhere near obnoxious. I welded the tip back on and it looks 99.9% factory. The hardest part is grinding the factory welds off cleanly so you are able to reuse the parts again.

Well , had to go check out what that sounded like .
.
It lost half of noise and 3/4 of the Growl when i held the stock 3/4 diameter tip back in place
.
And with the 3/4 tube i took out held in place it almost sounded just like the stock tip above held in place but even a little less.
.
My 1" baffle i lost 20 per cent of the Growl with the 1" open
.
And it even loses a little Growl just holding the 1 1/2 tip on the end over the 1" hole.
.
Looks like any tube extension tip will lose some Growl.

And just leaving the flush 1" hole is the best sound i'm hearing ..

Which was just dumb luck :confused:

I Wasn't going to. but you could just cut the 3/4 "section off and pull the 3/4 straight pipe out and leave the outer tip in place so it still looks like stock

Learning the above lesson , I looked for the pipe i was going with , a hindle evo for a sound check comparison , with and without baffle ;
.
again any baffle seems to ruin the deep growl (sub-woofer) effect.
.
I don't want the obnoxious loud pipe (with-out baffle),
.
So looks like I'm keeping the stock pipe on . even though its kinda ugly :frown2:

I just went for my first real ride after I took that pipe out. It's not too loud like some of the other pipes I heard and it looks completely stock since I welded the Tip back on. For nearly Free you cannot beat it (only had to buy some high temp paint to cover the welds I made. Took me around an hour in total and all you need a grinder, welder and some hand tools to do this.
