The loud exhaust has got to go, but the heavy long stock mufflers suck.

I saw today where someone cut off the turn out on their HK Sideburners.
I would consider that and see how many sink strainers I could put in the large pipe to quiet it down.
Bar sink strainers are smaller than kitchen sink strainers.
A pic of Prockey HK3 pipes with sink strainer and a serious lollipop.
Aftermarket pipes have thinner header flanges so the acorn nut could be bottomed out.
Flat washers or use regular nuts.
You may want to start putting oil on the nut/stud so it may come off easier.
For some strange reason studs break when acorn nuts are bottomed out.
Thread galling, so take it easy..
No more that 17 ft-lbs when tightened or loosened.

Hyper charger rubber hose frequently breaks off at fitting.
Check vacuum hoses for splitting on the ID.
Was the PAIR blocked off at the reed valve covers on the cylinder heads?

Air box flow changes are more critical than exhaust pipe changes, so hold off on the jetting.

I appreciate the reply and advice. Maybe a little above my pay grade as far as understanding how to go about implementing it

I am certainly willing to try the sink strainer idea
But Im afraid im not sure what or how to cut the turn out or what a lolipop is.

 

Here is a Sideburner with the end cut off. A straight pipe now..
It is on FB so you may not see it unless you have an account.

A lollipop is a flat washer in the center of the exhaust pipe.
Usually mounted on a eye bolt and can be adjusted to affect the flow and sound.

The picture shows the strainer farther in and the lollipop at the rear.
The sheet metal straps hold the washer aka lollipop in place.
Prockey found that his end caps had a space between pipe and end-cap so no screw or screws were needed.
The straps in his situation were bent back at a 90° angle.

The other alternative is put on the stock mufflers.

A reminder from TennX:
I use Fel Pro exhaust gaskets, get them at the parts store.... .
Fel Pro 60569

 

No sensor.
Sleeve gasket??
The parts fiche shows some gaskets, I thought it was more like a reducer..
I have been on aftermarket pipes since Dec 2005

What bolt tucked away???

Some header nuts are difficult to get to.
Sometimes a wrench required. My short 3/8" drive sockets can get 3 out of 4 nuts from what I remember.

I sent you a PM regarding SM.

The gasket I'm taking about is the one that goes between the exhaust and muffler. I see them on amazon but was wondering if they were as readily available at the auto parts store as the crush washers are. And the bolt I'm taking about is the one underneath the top one on the top muffler

 

FYI ...I use a wobble joint on the lower hard to get to header bolts...good luck OP

 

Damn! $400 for an hour labor, two tops if they're stopping to drink their beer!

 

My sleeve gaskets are ok. I had tried some other mufflers and it had a reducer bushing.
Looks like I pulled both mufflers off as one piece.
They are heavy!
I like it when the pipes go to the axle, just right for a "C"

It looks like the head of the clamp bolts are accessible from the shiny side!
