So whats the answer? An X or H followed by two individual mufflers in place of the maggy? :dontknow:
I take a very humble, but common sense approach to this subject. Internal combustion engine is an internal combustion engine. I dont think there is a magical combination to these engines for exhaust or that it takes a tuning prodigy gift from god to dial the tune in. Sure they have their querks. But physics is physics. I put 8 completely different custom exhaust systems on my last truck within 3 weeks. Different mufflers, crossovers, you name it. Ultimately the only changes were sound and amount of popping.
The stock system from the cat back is not bad. Its quiet. But if you look in it, its a perforated core (not even louvered) straight through muffler with a straight through resonator. Its even somewhat mandrel bent. The manifolds are decently long tubed, and free flowing. Most will tell you there is little change going with short tubes, and just a tad more with long tubes. Most cant feel the difference, and the cost ultimately isnt justified unless you have the money to blow, or like the way it looks. Once you get the catalytic converters off (The rears specifically) There isnt going to be much a difference in power, and seat of the pants difference between the the stock system and a 2k dollar header 600 dollar mid a 1k cat back system. The only difference a cat back is going to make is sound if thats the only thing that changes. If anyone thinks im wrong, go suck a dick. Told you i was humble.
The second generation magnaflow, what can i say, at least it doesnt rust as bad as the first. But it has a 2.5 inch bottle neck between the mids and the system. Doesnt do much good to spend all that money on 3" mandrel bent stainless system with hfc mids and put a 2.5 inch connector on it. First fail. And as i eluded to earlier the muffler's internal crossover is not befitting the dynamic of our dual firing v-10. It seems they just used it because it fit. It just doesnt make sense to me. And subjectively, it sounds like shit. (no offense Geodriller) At least the exhaust tips are pretty.
Your not going to make any discernable difference in output, swapping the system you have, or modifying the crossover or muffler selection, if the muffler remains flow through and not chambered. These engines, naturally aspirated require backpressure for the low rpm torque needed to get their heavy asses off the line. After the cats are gone, mission accomplished. You got the restriction out of the way. You changed the power curve. Now pick the rest of the sytem that sounds good to you, and fuck everyone elses ears. Make them blead if thats what you want......
