Removing the resonator...should I?

Just removed #7 myself. Sound is very deep. A nice little rumble on a cold-start and a bit louder than stock at low throttle. Mid to high throttle is where you really hear the difference. A deep nice sound that really allows you to hear the V8. As previously reported no drone at highway speeds and in my case no backfires/popping at all during deceleration. Its nothing crazy, although I could see how someone might think its a bit too much. IMO not offensive and only adds a bit of excitement when you go mid-to-full throttle. Its like having a stock valve system exhaust.

If you are on the fence I would recommend it as an alternative to replace the full exhaust system given that the current price for magnaflow systems are about $1100. All in all about $170 for the #7 resonator delete and tips. Very reasonable option since you really would not gain much performance from the full exhaust.

Today I just removed my #7 resinator. The very large one next to the muffler under the center of the truck. I have a 2013 Range Rover Sport GT Limited Edition 5.0 non supercharged. I must say I love this modification. The sport sounds amazing. Very similar to a Grand Cherokee SRT8. Some pics below.

I read through this entire thread and decided to pull the trigger for this modification for my 10 Sport N/A.

My local exhaust shop in Portland removed number #7 for $70. Without a doubt, this was the best $70 I ever spent modding a car.

At idle and cruising you can't tell any significant difference. During a cold start (high idle) or putting your foot into it you get a very nice burble.

For anyone on the fence, I would highly recommend you give it a shot!

Bumping up this thread coz I'm embarking on my own mod adventure tomorrow. Gonna be removing parts 7 and 9 only. Any idea if that is gonna throw off the check engine light? Hate to see that little symbol light up on the dash. Thats my ocd kicking in.

I removed resonator 7, the big one underneath the truck, on my previous '08 HSE and while it sounded good it DID drone on the highway, specifically around 70 mph if I remember correctly. I could shift it down a gear or drive slower to eliminate it, but it was there. It eventually bothered me so much that I put the resonator back on.

From what I've read, putting an x-pape in it's place would eliminate the drone and some of the backfire that goes with it. I had the resonator replaced with straight pipes before switching back.

Also, you won't get any kind of dashboard lights if you remove the resonator.

Thanks buddy! That was a quick reply!

Has anyone attempted to remove part 9 as well?

Do it. I'm considering the same. What's the worst that can happen? ��

Oh I'm doing it just need to know if x-pipe is a must to prevent backfiring or if you can straight pipe it on a 2012 RRS SC

No one knows if an x will do anything to change the drone or deceleration pop. Chances are it won't make a difference as the muffler isn't chambered separately so essentially it's a crossover and does the same thing an x would do.

Removed 7 and straight piped, sounds great! Does backfire a little when jumping off the throttle from being under load.. but it's not too bad.. if you're gentle on the throttle you don't really hear any of it.. Great mod

Now if you really want to step your game up and get maximum gains get some quality exhaust tips

Just got this done - WHOA. Sounds like a proper V8 should sound. For comparison, i'd compare it to how an ML63 AMG sounds, complete with the crackling/popping sound when releasing the foot off the accelerator after the heavy grumble.

Resonator was removed and a (custom, my Indy didn't have any on hand) straight pipe was put in place. $300CAD, but well worth it.

And, no drone unless >2500RPM.
