Mike,

You will need the mounting plate for the SRT where the pipes exit in the center. If you want to keep your trailer hitch, you will have to notch the SRT plate's outer bolt holes to accept the trailer hitch plate and mate them together. That way, you have the mounting brackets for the center tips/pipes. The tips will hang just low enough to be out of the way of the hitch. I am planning on doing this...right now I just have the SRT plate in place and have removed the hitch. At some point I'm going to want the use of the hitch and will need to modify the SRT plate as previously stated.

Since you don't have headers, I would swap the stock muffler out for the magnaflow unit with internal x-pipe. It will even out the flow to both pipes. You won't like the reso only mod, for you'll lose some low end grunt and gain some top end power...not good for rock crawl'n or daily driving.

The Magnaflow will help in the HP and TQ department as well as with the sound. The stock suitcase limits the flow to the passenger side exit pipe (only cold air comes out), due to the chambering/baffles.

Hope that helps...

Re: 5.7L WK Deep Sounding Exhaust

Ya, you know the saying...they're like a**holes...everyone's got one. Here's another:

Given all of the choices and ways to go about developing an exhaust system, one needs to have a general idea of what it is that he/she is trying to accomplish.

Before there were catbacks available for the 5.7l Jeep, I purchased a magnaflow universal muffler and couldn't stand the way it sounded with the MDS enabled...it basically "farted", for a lack of a better term. Even though I wasn't concerned about sound, but rather increased performance through reduced backpressure and lighter weight, I couldn't live with the "tone" that the Magnaflow produced. Then Borla came out with a system and I had to try it, for it promised to be everything I was looking for in an exhaust. Apart from a slight increase in drone, I was very happy with that system. It was as close to being unrestricted as I was going to get without sacrificing my ability to hear myself think while driving. Fast forward to the introduction of my headers and a 3" Stainlessworks system with a true x-pipe and the noise was unbearable...but the performance was the best I have had to date. Throttle response was awesome, as was top end power...the best of both worlds...but loud as f**k!

Now that I have the stock SRT system in an attempt to quiet things down, I have noticed a decrease in performance, but I can now hold a conversation in the car...

There are tradeoffs and endless combinations to be discovered. In the end, what works for someone else, may not entirely work for you.

However, it is the opinions of those who have experience through trial and error that can aid someone in deciding which direction they would like to travel in thier quest for "the perfect exhaust". Of course, these opinions should weigh heavier than ones coming from those who have no experience of their own. After all, they are only opinions and you're not really going to know what you like until you've experienced it for yourself.

Currently, I'm looking into ways to decrease the sound from the stock system or go with a completely custom fabricated system that will ultimately lower the decibles to the point of where my Borla used to be.

The search goes on...

Looks like it could provide you with what you're going for...deeper tone.

From my experience, the more you deflect the sound waves, the deeper the tone will be. You mentioned that you don't want a Flowmaster...well, one of the deepest tones I ever achieved was using the 70 Series SUV in conjunction with 3" mandrell bent Mike Leach piping on my old WJ. That was a great sounding, low rumbling exhaust!

Stuff to consider (from my personal experience): pipe diameter larger = louder; muffler design...more area inside the muffler = greater sound deadening and a 'deeper' tone...likewise, increased surface area (chambers/baffles/perforations, etc.) = 'deeper' sound; going from single to dual pipes = deeper sound

Also, straight-through round designs will generally have a higher pitch than their baffled/chambered oval counterparts, for the gases spend less time in the muffler and the surface area is minimal.

A muffler that I would like to see someone test is a Hooker Aero...it should produce a deep, low rumble, while maintaining optimal flow characteristics.

Re: 5.7L WK Deep Sounding Exhaust

A Hooker Aero? Do that make them for our 5.7L Jeeps?

Re: 5.7L WK Deep Sounding Exhaust

I must say I love my Borla with the reso deleted. I got it from a buddy who had it on his 5.9 Durango.

No drone @ 70++ mph on the freeway, @ WOT it is VERY loud, but when i baby it you have no idea I have an exhasut. I will try and do a video for you tonight or tomorrow...

Check 'em out here...they aren't very large, but supposedly have a unique chamber design that helps to eliminate high pitched sound waves...

Times have changed, so have the sounds and brands. It was a good read though, but it would be nice to see an up to date grouping

And still I think my old Jeep was louder. Ask people on here for real life testimonies. LOL
i personally rode in his jeep and was amazed by how loud it was

Re: 5.7L WK Deep Sounding Exhaust

I'm sticking with the Dynomax! I looked at the Hooker Aeros and I'm just not too sure about them. There are a lot of reviews but I don't want it sounding like a chevy...Lol. As they most go on.
