And after the N.W.'s downpipes, used a Magnaflow tru-x crossover pipe in place of the factory H-balance tube. My Magnaflow SRT6 resonator back muffler sounds great IMO. No dynos for me at this time, but it sure feels like 20whp(or maybe it just sounds like 20whp). If it was a track only car, then I might drop the heavy resonator and wear ear plugs. When you get your system completed and it doesn't drone somewhere between 1800-2500 RPM; then I will be happy for you. Then again, perhaps you don't care about a little drone. I'm certain that the AMG boys had to work hard on that resonator to cancel the bad frequency(apparently between 133-138Hz for those that may be interested. lol) I admire all the guys and vendors here on the Forum who have pushed the limits(and spent a lot of money), and figured this stuff out. Compared to them, I'm just a follower here(and like them, I too have spent a lot of money).
I got what you meant, just feel confidant. I too am using the Magnaflow x-pipe muffler(A very nice piece by the way), deleting the resonator and replacing the nice stock muffler with the Borla. I'm keeping all of the stock pieces intact so they can be used if I don't like the system I am trying. I have poor hearing and sounds like the drone of a poor exhaust system actually hurts my ears.
Jerry has been very cordial making recommendations for parts(the 550cc injectors) to enhance the tunes he has provided. Chuk I have reached out to you to be friendly and offered to pay you for services and at first we had a nice common ground relationship and I believe it was the mention that a tune is nothing more than air/fuel and ignition timing that got you "upset"? Why can't we shake and let bygones be just that? I'm looking forward to a pic of us shaking hands after my AMG routs your X-fire, head to head! LOL just joking Chuk. I have the utmost respect for your work as your expertise precedes you. All I have done myself is change the valve cover gaskets, injectors and the DCAI. I was likely disabled at your age.
I'll give a fair report on the catback when it is complete. My one concern was going with a 3" in/out Borla as a larger pipe will enhance the drone and many V8 guys go overkill with 3" exhaust systems.
