[QUOTE="SVTRocket, post: 5946899, member: 16038"] Quote: "The biggest restriction in the stock exhaust system is the four factory cats, not the mufflers". Not according to Magnaflow...They provide the most data that I have been able to locate. Maybe you know something I haven't seen... Magnaflow Exhaust Dyno Muffler upgrade: "Our first re-run on the rollers showed we were on the right track. We found 296-peak horses at 6,000 rpm -that's a gain of almost 20 horses just from the muffler upgrade! Torque numbers increased to 297 lb-ft at 5,000 rpm. That's 20 lb-ft more. It's certainly got a meaner exhaust note, too." X-pipe added to the mufflers: "The results were not as eye-opening as the mufflers, but we still picked up a couple horsepower (297 at 6,00 rpm) and some torque (298 lb-ft at 4,500 rpm)". [/QUOTE]
