How To Install The Gibson Muffler

**hydrojunkie** · 05-29-2008, 07:51 PM

Sorry For Not Including Directions With The Kit, Due To The Fact That Gibson Drop Shipped What You Have Now. Future Sales Will Include Directions And Hardware,

You Will Need To Have A Rear Thru Hull Tip Installed To Use The Muffler. Once Installed You Will Remove The J Pipe And Cut The Tail As Shown.

Now There Are 2 Ways To Inject More Water Into The Muffler.
1. Use The 1/2 Inch Bung On The Muffler.

To Use It Simply Cut The Waterline That Goes From The Exhaust Manifold To The Jpipe "the Bottom One" And Connect The Supplied 1/2 Inch T To The Hoses. Then Using 1/2 Hose From The T To The 1/2 Inch Bung And You Are Done.

Or You Can

2. Drill Out The 3 Pissers On The Bottom Of The Jpipe To 1/4 To Allow More Water To Flow Through The Muffler.

There Is No Wrong Way To Do This. The More Water That Flows Thru The Muffler The Quieter It Will Be, The Less Water The Louder It Will Be.

YOU DONT NEED A BRACKET FOR IT TO USE IT, I AM HAVING THEM MADE, IT WILL JUST SUPPORT THE WEIGHT OF THE MUFFLER ON THE JPIPE.

Isnt there a line that already comes from the manifold to the Jpipe and T's off to the original waterbox or thru hull ???

Here are pics of my install. Everything goes together well. My silicone coupler to thru hull fitting is 5" but 3" or 4" will work fine too as the muffler is long enough. The stock black J-pipe to waterbox coupler works fine. I recommend a minimum of 3 clamps, 4 would be beter. Jason will be supplying a 1/2" tee and 1/2" hose to replace the stock tee under the J-pipe for the water hose barb on the Gibson. Remember to cut the J-pipe to 1/2-5/8" below the weld where the pisser holes are and you are all set. 2 more pics follow...
(By the way, I do not work for Black Magic and I do not get a discount. I just think he has a good product and I'm happy to help with testing and presenting.)
