I'm no exhaust expert, but I went from stock exhausts, to true duals on my 87 Vette, and it ran like crap!
Wen't to a local guy, an ancient dude who had retired from the muffler and exhaust business and has been doing custom exhaust for almost all the rodders and musclecar guys in the area for years, and he immediately said "let's put an "X" pipe in there!"
He did, and the performance went way up, an improvement that was immediately noticible from a the seat of the pants and throttle feel!
Fuel economy also improved a tad as a side benefit.
He said it was about increasing a little backpressure in the system.
I guess it was too "unrestricted" before.
HTH?
