Re: DIFF. BTWN SS EXHAUST AND REG. Z28 EXH. ? The SS muffler is by SLP. It give a lower throatier tone. At idle it's nearly as quiet as stock but it really opens up nice at full throttle. Very low restriction.

Re: DIFF. BTWN SS EXHAUST AND REG. Z28 EXH. ? Also (at least on my SLP CME) the muffler is a
lot bigger that the stocker and looks like a
hand-built full stainless job. Its exit pipes are
2.5" (where the Z/28 exit pair look pretty thin,
but I've never measured those). And the I-pipe is
3.25" OD although it necks down to the standard
3" at the slip fitting to the Y-pipe.
Purported to be +10HP on a stock vehicle in GM's
Camaro literature so it's probably true, and then
some; these SLP exhausts are half of the 345HP
(+20HP) SS option package (the other half being
the SLP Blackwing lid). I only got the 335HP
option on mine (bought mine late in the year, got
whatever SLP was hanging on cars that day).
The CME is annoyingly quiet.

Re: DIFF. BTWN SS EXHAUST AND REG. Z28 EXH. ? I believe the I pipe on the SLP is actually 3" and not 3.25. I say this from first hand experience last weekend. The I pipe actually slips over the end of the Y pipe. When I tried to connect the SLP I pipe to my Kooks 3" Y pipe, I found they were the exactly the same diameter. I then looked at the stock Y and found that the end is reduced just a little to allow for the 3" SLP I to fit over it.
