Billy Boat Exhaust
 

Just put a Billy Boat Exhaust on the Hummer.

I got to say I love it, it sounds awsome!

It has also made a significant difference in power. I know alot of folks say go dyno it before and after, blah blah blah.

There was an instant notice in power from throttle response to gas milage and no more humting gears on the autobahn while going up hill.

:perfect10s:

I should have looked into the Billy Boat before purchasing the Corsa Sport.

If I did, I would have definitely gone Billy Boat. It's way better sounding and deeper growl.

I thought Corsa Sport sounded good, ...that is until I heard the Billy Boat at a custom shop.
:iagree:

Congrats!

I had a BB on my '06 Porsche Cayman S, and I'm sorry to say that it was not well made. I went through two sets of mufflers, due to cracking welds, and finally bought a Cargraphic. I thought the system sounded great when accelerating, but the drone was terrible when cruising.

Do you have a sound-clip of your hummer?

Re: Billy Boat Exhaust
 

Sorry no sound clip, but there is no drone.

I found the system on sale for $690, by the way/

Re: Billy Boat Exhaust
 

$690? That's a no-brainer. The shop from whom I purchased the exhaust had very good things to say about BB, especially when used on Vettes, and such. I think I just had a bad batch....twice.

Yes I could not pass on the deal, they also had the OEM floor mats on sale for $99.

I just looked and the price is back up to 1,229.00 again but the mats are still on sale.
