Finally got rid of the stupid turn downs. Fun fact: If you happen to acquire N62 4.4 tubes for the flanges, this is a stupid easy install. They insert into the 4.8 pipes almost perfectly. Make a slight positioning tweak, tack, go.

It's close enough that you could probably get away with clamps. (Last pic shows the difference between N62 4.4 pipe vs. 3.0 pipe.)

Exhaust tone is very slightly deeper, and there's a hair more noise when you get on it. The goal was no-more-turndown, so minimal noise changes are good for me. I was a bit worried after seeing some sound clips, but I think that those also included a resonator delete.

Do the 4.8 mufflers look the same size to you as the 3.0 or the 4.4, other than the tips of course?

When I swapped 4.6 mufflers onto my 2003 3.0, I was surprised to find that the only noticeable differences were the tips and a slightly larger pipe (10mm larger dia.) While the mufflers were identical, from the outside at least.


I will add that the swap was worth it for the looks alone. The turn down tips are so bad looking.

4.8 mufflers are definitely different. Iíll be going back to swap out for the 4.8 heat shielding as the 3.0 shielding touches.

Looks Good!! [emoji106]

I totally respect that not everyone wants to be heard a mile away. ;)

That's cool. I don't think there was any power gain, or change in noise, from the 4.6 muffler swap at all. Still I am happy with it. I agree that on a DD you don't want to annoy your neighbors.

LoLÖ My neighbor has an El Camino with two 750ís on a FAT ASS blower on something like a 6.0L, with headers and a dual 3Ē exhaust. That car vibrates the walls, so I am pretty sure I am good with him.

Although my E53 is my DD, I generally only put about 400 miles on her per month. So I donít think I am disturbing them often. But in the back of my mind though, I am sure there are some neighbors that probably have an opinion about both my neighbor and I.

Honestly, iím a lot more concerned about my driving fatigue and also tinnitus. One of my life regrets is not taking better care of my ears, especially while racing.

I used to drive cars with fartcans when I was a kid and thought it was cool. And I love racecars and if I ever get that FD RX-7 that I someday hope to daily drive, I will probably put a fart can on it too.

But now that I am an adult, nothing makes me madder than my neighbor's kid and his friends, who are Diesel Bros, who love to sit outside in their fartcanned F-250s at 9pm just idling and checking their phones. All. the. time.

And who think that their modern diesels (all 2010 or newer) require 25 minutes of warm up every morning at 7am. So loud I can hear it in every room in my house.

I fully recognize how dumb I was as a kid... I was pretty dumb. But I just don't remember ever being that dumb.
