Stock Catback too restrictive for my mods?
Full bolt on's with a MS3 cam, ported TB etc. I had the LM1 on it, but with the MS3 it was way too loud so today I put my stock SLP catback back on and it made it sound much better but The car has been dyno tuned with the LM1 and im wondering if the stock muffler is restricting it too much....

Its stainless steel if that helps. I dont know if they are stainless or not...the muffler itself is 21" long.

Over 140 RWHP and over 60 RWTQ is damn good with boltons and a cam. Hmm curious. And yes the stock exhaust(non loudmouth etc) will be restrictive to you since being tuned with the better flowing system.

I have a 02 SS with the Y2Y and WU8 RPO codes.
Heres the day I brought it home with the pea shooters.
Heres the stock muffler, 21-22" long with a 2 3/4" intermediate pipe.
Heres the SLP Dual/Dual I bought brand new from SLP in 2004. It has a 3" intermediate pipe.
I did call SLP and they told me my build number and the date it arrived and left.
If it looks like the muffler being measured then yes. If it looks like the one with the CME then no. It sounds like you have the good one.
