Exhaust loud. Any way to quiet it?

If you are sure that you don't have an exhaust leak, measure the ID at the end , you can buy an inexpensive motorcycle baffle insert that slides inside . This is an example:

OOO good call on the baffle. Didn't think about that.

But in terms of the A1, are others resulting such harsh raspiness? The clip below sound much deeper (granted it's in a garage echoing)

Sounds like music to me :~)

I'm planning...#2 daughter is coming in a week-ish and her nursery is right above the speedster's garage bay!

I don't want to feel like I'm sneaking out like a teen any time I drive the tub !

DUB - for audio reference, here is a short video of my previous VS with A-1 Sidewinder. It has a Magnaflow muffler which as you will hear has a great sound under acceleration and a mellow tone at cruising RPMs. Maybe the muffler on your is a Flowmaster which is noticeably louder. Otherwise, a baffle is a great idea.

Ha! Yes yours was the one I was jealous of! There must be loose bolts causing a leak at the motor. The exhaust is fairly new.

I'm going to explore the the baffle sounds like the cheapest option right now.

Thanks

If you use the baffle you may want to recheck your timing as it may slightly alter the back pressure.

Dub, you are comparing two entirely different motors. They won't sound the same...Webers vs Kadrons, cam etc.

Any pros and cons to baffles...I know the goal on my S4 is to get the charged air thru quickly so I've got a large diameter downpipe back system to open up the flow. Will a baffle sacrifice performance for sound on the speedster?

Bill, I understand it won't be apples to apples but I just want to achieve anything deeper than the brappapap-fest I've got now without having to replace the exhaust system.

That does sound a lot louder and raspier than mine.  Like Musbjim, I have a Magnaflow, but mine sounds deeper than his under acceleration.  When I first installed mine it was incredibly loud due, I subsequently found, to my forgetting to tighten the nuts at the front of the heads (DOH!).

The PO installed the exhaust on mine and I never went back over that part when I received it. I mostly just checked the suspension. I'm betting something possibly rattled loose or was never torqued right in the beginning...I hope for sound's sake. 

Good to hear others have a mellow sound...mine sounds like a track car!

I suggest Dynatech exhaust augers.  We've found that while they don't quiet as much as most inserts, they do quiet exhaust noticeably and without much restriction.

This sure sounds good under hard acceleration (musbjim). Edit: saw that this was already posted above

Getting baffles to fit is easier said than done, as there isn't a lot of straight pipe to work with. In one of the 9452 permutations of exhaust I've run, I built a cone out of perforated stainless steel. It was about 3" long (maybe less), and the big end was about 2-1/4" in diameter. I welded it to a header collector flange one size smaller than the exhaust, and sandwiched it between the header and the muffler side collector flange. 

I pointed the cone at the muffler (inside the pipe), and the difference was astounding. The theoretical open area of the perforated cone needed to be greater than the I/D of the pipe in question in order to not be a choke point, but I still hated it because it struck me as a bandaid.

FWIW, last time I bought, Tiger wasn't using MagnaFlows any more-- he's got his own "A1" branded stainless mufflers, built along the same lines.

Yea, mine has a A1 stamped in on the muffler. I've dealt with Flowmaster and Magnaflow on my Heeps and there are no indications of either.

Lost a nut on the flange to the motor causing g loose pipping/ rasp. Replaced it and got the mean a1 tone! May still look to baffle more with an insert.
