I installed the Gibson exhaust.
I expected more but I got less.
I will admit, the sound is excellent. Nice strong throaty bark!
This pic shows how the system didn't line up on center.
I did everything in the book to get it on, or close, to center. But that led to other clearance problems.
Too much pipe length here & there.
However I bent the lower support, the mid pipe would either hit the head, header or hit the gearbox.
Now... if it is for proper power output (tube length), I'll give them that, but it could still line up on center & be further away from the motor.
This pic shows how far off the spring retainers are.
Geez... not even close.
This pic shows how close the Midpipe is to the valve cover.
Header wrap is a must.
the lower mount was retarded as well.
Total hack job.
I had to die grind it to smooth it out, cut 1/2" off the top, It was too long.
Then I mill cut the lower bolt hole (cut the weld out & back) so I could get the nut on it & a socket to tighten it down.
This pic shows an aluminum seal seat I had to make for the back of the muffler.
Either the hole in the muffler was made too big,or the head pipe flange was made too small.
As well as them wanting to use the stock seal, no biggie if done right.
If the muffler was ever so off of a dead straight alignment, it would punch right through the back of the muffler. It happened twice during spring install.
So now with the seal seat it can move around all it wants & it will stay sealed.
Anyone without a lathe would be S.O.L, having this kit as it was sent to me.
This pic shows the muffler mount.
Not too much thought put into it.
A little to "automotive" for my taste but it's not a show car.
Effective & functional I suppose.
This pic shows the oulet, less spark arrester.
Gotta get rid of the button head screws & replace them with some safety wire-able flange bolts or cap screws.
These are just gonna strip out or fall out.
I'll keep it for now.
Just gotta test it & see how it holds up.
It does sound good.
This just goes to show ya, Never order something around the holidays.
