Being a man blessed with more sense than money, paying hundreds or thousands for no significant performance gain seemed ...well, irrational.

So, i had a local shop do the lpmm (byass) mod for $100. Sounds goods.

Sorry about the crumby pic... I put them on before thinking about a photo!

that's exactly what I did many moons ago...pipe + install was around that price...

 

I've had the LPMM for several years....Really nice sound for just a little money/effort.

 

Smart man!

WOW interesting weld beads.


It's LPPM, not LPMM
as in
Leland Pete Muffler Mod.

 

I have the same and really like the sound. I will be checking out some Fister's this weekend to compare.

 

you get crackle/pop?

 

Why would Leland Pete Muffler Mod be LPPM, not LPMM?

 

I think the welder may have used a sub optimal method... MIG maybe? I'm not a welder but I read that TIG is the way to go on stainless.

 

A bit more. I've been running muffler-less for a week... So, once I regain my hearing, I'll let you know for sure.

 

Stands for" Leland Pate Modified Mufflers"........LPMM

 

Uhh...That would be LPMM not LPPM And I did these many many years ago on another 993 and loved it.

 

Thanks for the correction!

 

2 inch or 1.5 inch bypass? I assume 1.5 inch would be slightly quieter. Can anyone confirm this?

 

yes, I have 2", sounds good, but next my now supercups....they're super quiet.

 

Here's my lpmm:
