Just finished my fabspeed premuff and muffler install

Thought I would share some pics:

Now THESE are rusty nuts.


Only one came off without extraordinary means. Here are some tips, that I came to on the very last nut

1) PB blaster of course
2) Don't fiddle too long before you cut. Nothing burns time and knuckles like this work.
3) I used a cutoff to hit the ones I could reach, and I used a nice $45.00 carbide bit on the die grinder on the others. The secret is to make a cone shaped tunnel on the bolt, making a nice big pocket for a nice sharp large drill bit. I then used the 1/2 drill to eat the bolt and nut.
4) Don't be surprised if both ends of the bolt are cut and it still won't come off. I had to really whack (and bend) a good sized drift to get several out. The bolts are bright red and very very rusty on the inside.
4) Buy new gaskets. Mine were just a whisp of what they once were.

Really happy with the result.

Congrats!! Did it make a noticeable difference in power?

Hard to say Scott, I think I can safely say it spools up quicker. The sound is worth it, it sounds very powerful now, not too obtrusive.

I think it's safe to say that this helps reduce the "carrera lag". It also is clearing the way to the turbo from Souk once he hurries up and gets it done
