Re: How to make a 5.7 Hemi sound like an actual 5.7 Hemi

I'm sure it's not for everyone, but I first deleted the resonators in the rear to get a little extra grumble out of my 2011 GC overland summit 5.7. I also welded in some 4.5" oval tail pipes. I liked the sound but after about a year I wanted some more out of it (You can probably find my previous video of how it sounded with no resonators). My most recent decision was to cut out the center suitcase muffler and add in (2) flowmaster HP2's. It sounds pretty mean now. Like I said, not for everyone, I know, but I like it. Here is a sound clips and photo of the mufflers. The iphone clip doesnt do it any justice. Sorry for the sideways filming.

A complete cat back would probably make it even louder if you go Flowmaster or one of the other bwappa bwappa bwappa brands.
I've never seen that. In WA, they plug in the OBD and you're set in about 5 minutes.

Bellevue (factoria area) and Redmond. They all use a OBD2 connection and call it a day. I have a lower car that can't get into the Bellevue location without destroying all of the carbon fiber on it so I take that one to Redmond. Both use OBD2.

Keepittight, did you notice any low end torque loss when changing the exhaust? I did the exact same thing you did, except with a magnaflow muffler and I feel that I possibly lost a little grunt on regular acceleration.

I did, a little bit. I wonder of an X or H pipe would help. Do you have one?

I have the 11386 magnaflow 14" muffler with the built in x pipe and still a little loss in low end torque. I was talking to Sean from hemifever and he expressed that's typical with an exhaust.

Re: How to make a 5.7 Hemi sound like an actual 5.7 Hemi

I would really like to hear a video of how this sounds with just the x pipe and stock resonators! I am going to be doing something to mine shortly and need to decide between this or a magnaflow 14" true x muffler and the stock resonators...

Can you post one up of you driving away so we can hear what it sounds like?

Thanks!
