1641 Exhaust Choice

[sactojesse]

Interesting article. Still prefer dual quiet packs. If you want to do a mondo muffler style and want max performance, you may wish to consider pairing one up with CB's 1 3/8" merged exhaust system:

It's a true merged exhaust (look at the length of the collector) and not merely a standard 4 into 1 extractor like the link from MAMW you posted earlier.

My appologies for the late reply.
I went with the mid america stainless 1 3/8" merged 4 to 1 and the fat boy.

The quality looks pretty damn good, the guys at the shop liked it. The 3 bolt flanges, however, were warped so I need to take care of that.

Im also having a fitting issue between the fat boy muffler and the header itself, it also hangs way to low for my taste as the pictures show it tucked up nice and neat.

Looks like we are going to pie cut it and weld it back up.

I was kinda pissed last night after trying to add the muffler a 10pm and the fat boy not fitting (it hits exactly where the jtube/heater box connects)
But other than that Im pretty happy with it.

For some reason today I got this gut feeling to take pictures, and I did hahaha.
I've got them on my phone so I will email to myself and write a report.

Ok, so the header was pretty nice and went on relatively easily.
I didnt have the industrial tins and stuck with my heater boxes for now, will eventually install supplied J tubes.

I am to believe that this is actually an EMPI header which kinda shocked me. MA doesnt have this listed as an EMPI header so I was kinda bummed by that as we all know EMPI sucks.

Any who, the fat boy didnt fit for crap and it did hit at the banjo clam thingy that connected the header to the heater box.

The muffler itself also hung down WAY WAY WAY to low.

I work at a place with access to TIG and my friend helped me weld it.

The biggest concern is the flange and how the collector points down to the ground which begins a mass of problems, if it were straight it would be fine.

We started by cutting off the flange from the muffler side

Then sanded smooth and flush and bolted to the header which is the first picture.

I held the muffler up where I wanted while my friend made the pie cut line
in silver sharpie

We didnt actually cut it that much but we cut it maybe an 1/8 to 1/4 from that line actually then test cut off of that. Not really precise.
You can guestimate here

We tried welding it on the header straight but it didnt work. So he sharpied notches to line up and bench welded it tacking it in place.

We fit it on before fully welding. Saw it was good and he went to town.

Engine seemed to run much hotter but I need to tune it more.
