Exhaust that's throaty, yet legal! lol
« Reply #20 on: June 16, 2010, 07:29:20 AM »
This is EXACTLY the sound I was looking for!!! I just hope I can do it without too much grief! I looked at the cutout setup and it's just a little too rich for my blood bc I would want to do the electronic switch due to my "geek who loves buttons and gadgets" nature.

Thanks again!!!

I have just over $600 in my cutout setup.  Like I posted earlier, I ride with the cutout open most of the time.

First I apologize for bringing back an older topic but I thought my post would fit in here rather than starting a new one. And second I have yet to take pictures or do sound clip so two strikes against me right off.

I wanted to replace the stock muffler/resonator and have been looking at the catback versus muffler minus resonator. I finally had the funds to do this and decided on a Magnaflow muffler (  http://www.magnaflow.com/02product/shopexd.asp?zone=main&id=8941   ). I bought the muffler from a local speed shop (Parks Auto) for just a bit less than half the listed price. The muffler shop (Jimmy's Auto care) I've dealt with for many years is located next door to Parks. And just a side note Jimmy has a '05 Avy for the shop truck. He has full duals using Thrush turbos ,mounted side by side,that sounds great but is a bit loud for me. It was cleanly done but would there be any benefit to going full duals after cats? We got to talking more about Avys and I told him about the club and site. Back to my truck the Magnaflow I chose is quiet at idle ,not much above stock, but lets you know it's there on throttle. It would be comparable to a Gibson setup I had on my '99 Ram 360. Jimmy's installed the muffler,removed the resonator and installed the tip for $150. I'm very happy but might one day go to duals if I switch to shorties.

I would say that there is most likely a benefit to going with true duals, although my muffler installer didn't want to go that route due to the location of the gas tank and spare tire.  Sounds like your guy has it figured out for his truck though.

Main One I was thinking on an Avy with mild mods (ie:CAI,performance tune) that full dual exhaust might be overkill on mine. The factory is 2.71" with clean bends anyhow just in need of a better flowing muffler and no resonator. It was interesting how they did it though,similar to a Jeep FSJ . It was crossed over at the front at the stock down pipes then run parellel through the mufflers then branched around the spare. If I remember correctly 2.5" duals give a similar volume/capacity as a 3" single setup. And 3" dual would lower back pressure to much at the expense of low end torque on a setup like mine. Please correct me if my line of thinking is incorrect on this. I may go the dual 2.5" route someday if the modifications get to that point.

I don't think your thinking is incorrect.  You seem pretty knowledgeable.   :thumbup:
