		Going from stock single to true duals is good, but the real gain is in headers. Most say 40~50 HP gain when converting a 390 from stock exhaust to headers, with a 352 I'd say 30.  The Performer is not much better than a stock S code 390GT intake, just lighter.  A pretty good choice for heavy trucks and the 352. I'd look for a 25~35 HP gain, but you should consider long headers, you've already got the rest of the setup for it.  |
