I found a picture, and I'm amazed at how quiet the muffler is now that I've SEEn the insides. It works amazingly well.





SLP 2 on the left muffler insides

Well it's not whisper quiet. But considering I'm almost 11:1 with the AFR heads, the cam is pretty decent, and I have LTs no cats and just the cat back its pretty darn quiet.

Much quieter than other cars I've heard with similar builds.

Looks like a pair of glass packs welded into a single case.

Re: Whats the inside of a SLP 2otL muffler look like?

Its pretty much a huge glass pack like magnaflow and borla.
(IIRC borla made some of the 1st stainless TOTL mufflers for SLPs firehawks)
There are a few different designs of the muffler SLP went through. The 1st being made by walker with expanded oval tips instead of the baloney slice 45 deg tips.
I think I have around 5 TOTL systems.
