i have definitely heard mine back fire
HAHAHA.. WOW! Just deleted #7.., didn't expect that. I was outside of the shop walking around and heard a crazy exhaust start up.. I knew it was mine, but didn't believe it. So much louder than I thought. Coming from multiple high HP cars with modified exhausts.. the 'stock' exhaust is loud w/out #7. Backfire it does.. quite a bit actually. Slightly embarrassing pulling into the neighborhood.. but the smile I had during my usually boring drive home was infectious. To each his own.. its louder than you think if your contemplating.. but I like it. lol.. not sure what the wife will say though.

Glad you like it. I loved the sound especially when you accelerate but the backfire drove me nuts. After a month of having it I ended up putting the resonator back on. It seems like the backfire is more on a supercharged bs HSE based on the A/F mapping. Even with a full exhaust system it seems like you will have some backfire all the time.

I took both resonators off and that huge muffler that looks like a gas tank....I get compliments all the time on the road now....I would never want to drive a quiet RR again...
This is my very first performance V8 vehicle and I love the stock sound. And besides, I live in a town home with great neighbors glued next to our unit and I keep the rover in the garage. I think hearing that thing fire up at 5 in the morning is bad enough for them. I can't imagine they'd be thrilled at a louder exhaust with no res.

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.

About to do this on a 5.0 SC - so is the verdict remove 7 and must do the x-pipe to cut down or prevent backfire?
taking it to get this done, really need to know if the x pipe is a must for it to run right not backfire, does it enhance sound etc?
Do it. I'm considering the same. What's the worst that can happen?
