Absolutly. Can't beat the fact that other than the motor being stroked to a 408, it's a really simple motor. It makes really good power and fully dressed, it weighs 500lbs less than the 454 I took out of the boat. Next I'd love to get my hands on a 28 Pantera with twin big blocks and LS swap them.

Just wanted to update this. Bob Teague called me tonight after he was alerted to a message I submitted on their website and to this thread. Without going into details, he has made everything right, and has earned my future business. He's a real stand up guy and talked with me about my exhaust problem, gave me some options and his honest opinion, which I greatly appreciated. Its good to see that even somebody with as big of a name as his in the marine industry still genuinely cares about the little guy like me. Kinda refreshing.in this day and age.

Sounds like everything worked out with Teague Marine. What solution did you come up with?

Kind of the same thing that had been discussed here. My best option was going to probably be a set of Gibson Bullet clamp-on mufflers, but with no water through them, they wouldn't last as long as they should, and probably wouldn't do as much muffling as they would with water. So, I have decided to just deal with the sound for now. I can't justify spending the money on a set of new mufflers just to destroy/discolor them. And who knows, maybe all the noise will make me get on my turbo build that much faster.

Clamp on's you have to worry about feeding them to the fishes, and they need water.... GGB inserts all the way!! I've used the 5" long and now 8" long competition versions in my 5" dry pipes and absolutely love the sound. With my low transom height, 5" dry pipes were deafening in the rear seat at a 4,000rpm cruise, and barely tolerable in the fronts, even though I'm a hard core noise lover.... Knocks it down alot, but still has a great strong sound - more muscle car than nascar. If you research it, you find people seeing maybe 5-10hp loss with their regular versions, and the same or sometimes nothing measurable on the comp versions.

I actually had stainless marine build my tails with dumps at the bottom, so the bolts for the mufflers could go up thru the dumps and not be seen SM puts ramps inside between the inner and outer pipe to help direct the water to the top of the tip when doing bottom dumps. Also tucked the inserts back 3" so they wouldn't be noticable. In video, timing was advanced a good bit for initial startup... Removing the inserts takes about 10 minutes for when I want to be obnoxious...

How do I find the GGB mufflers and see what they have to offer? I have tried their website, but it always asks me to log in and says it's for dealers only.

Happens to me too. Click on their snowmobile link and that works. Sure there is a phone # there.

Edit in : Here https://snowexhaust.ggb.ca/index.php...=cms&id_lang=1

one of the big performance marine parts guys carries them and has all the info - like CPperformance or ? forget who. Less than $300 a pair now I think

I actually found them on eBay of all places. Looks like what I would need it less than $200 a pair. I think I am going to buy a set of their competition series and build my own clamp-ons to test. These LS motors seem to be really sensitive to back pressure changes, so I want to be able to easily remove them if they cause too much power loss. Thanks again everyone!!


Oh, by the way Hang Time 27, that little Cig is SWEET!!!
