Muffler Delete, Do You Recommend It?

[tman52804]

SATXLS3,

Now I'm worried. Did you have the Magnaflow resonated x-pipe installed or just a muffler delete?

[tman52804]

Caverman,

Listened to the videos a hundered times, sounds good. I don't notice the decel/popping when slowing down. Do you suppose it is much worse without the magnaflow x pipe?

I honestly don't know because I've had the resonated X-pipe the entire time. However, Jordan at JDP says that the resonated X-pipe does tone it down. I do hear it some inside the car but I can tell you that inside the car it's much quieter than outside. Not that it's real quiet inside....it's just quieter. I hope to get some video...maybe tomorrow....and I'll get some in-cabin stuff. I'll try to make it doing the popping to see if that will help you make your decision.

I will say that I can't imagine that the any system is going to remove the popping completely. It's there....even from the factory. When you have a louder exhaust you are going to hear it more. That's just my take on it. Keep researching and looking around. You're doing the right thing in listening and asking questions.

My opinion - after doing several new Camaro exhaust jobs.
For L99/A6 cars:
The muffler delete is quick way to a BETTER muscle car sound - good but not great. The tone is a slightly junk yard combined with a little wooshing at full throttle. The AFM mode is very annoying - even with the stock center resonator. Drive around in Tap Shift mode or get a tune to de-activate AFM.

Doing a muffler delete and replacing the stock center resonator with a Magnaflow True-X muffler results in a GREAT sound but the drone inside the car is annoying. So, this combination needs a pair of small 4 x 8 in mufflers to tame the resonance.

For LS3/M6 cars:
The muffler delete is just too loud and too much decel popping.

Using a pair of Magnaflow 4 x 14 in round mufflers is just about perfect. For a quieter sound level, use a pair of Magnaflow 5 x 14 in round mufflers. For a louder system, use a pair of 4 x 8 in mufflers. And, the decel popping will still be there. The right tune can diminish the popping to a tolerable level.

SATXLS3, what shop did you use?

Geared - Up in San Antonio is part of Gunn Auto. They are located on IH 35 @ Judson Rd next to Gunn GMC. They installed MBRP 3in cat back in about 1 hr. Great service and a warranty!

I had only the delete. I was not going to spend more $$$ HOPING that it would get better. I too watch hundreds of videos (just ask my wife ha-ha) I noticed on some that had excessive poping that the driver would coast in neutral up to the stop signs. Maybe driving technique? or to noisey? could be either. My new MBRP 3in system has the x-pipe and you still get the popping but it is muffled nicely. Good Luck

I did a muffler delete and I like the sound, but I don't care much for the popping. Here's the deal: I have a Harley with drag pipes on it. It didn't crack and pop until I took the baffles out of the pipes. The baffles obviously eliminated the popping. What I was wondering is if I took a very short section of my baffle and inserted it into the tailpipes of my car if that would eliminate or reduce the popping? Hmmm, just a thought? By the way, the baffles are only very slightly smaller than my exhaust on my car and they would fit inside of them perfectly and then with a little welding they should be good to go. Maybe I could jam them in there a little ways and then take it down the road and see how it does before I weld them.

The largest difference between the 2 scenarios above is the x-pipe (10791) with the factory resonators isn't going to flow as well because of the factory pieces and it won't sound as refined. The resonated x-pipe (11386) is straight through and everything is contained in 1 package. The price is very similar between the 2 products and I think the horsepower difference is going to be minimal.

It really comes down to what you want to do. I think the resonated x-pipe makes for a cleaner install. Please feel free to call, email or PM me anytime with questions!

We appreciate everyone's support and have a great day!

Kind regards,

Jordan

So with an L99 I need the 11386 resonated x pipe and nothing else?

That is correct. The 11386 will help tone down the popping on decel but it's still going to be there as with even the OEM system. Going to a freer flowing exhaust is going to increase the sound regardless. This option basically gives you Magnaflow 16580.

I've always offered multiple options and generally it's driven by what the customer wants. You wanted the resonated x-pipe so that is what we sold you. With our experience this has worked well with some drone when AFM kicks in but use of the tap shift helps. On the LS3 it sounds good and has an aggressive tone like the 16580.

These are all great recommendations and things we've used. My favorite combination is Magnaflow x-pipe part # 10791 in place of the factory h-pipe/resonator(s) and (2) Magnaflow 14363 4"x9"x11" (Loud) or 14326 4"x9"x14" (nice aggressive tone). This combination is like a 2.5" version of Magnaflow 16483 which is the 3" Comp Series cat-back.

I've always preferred going with a cat-back because it is much cleaner and the sound/performance was tuned on a dyno as well as the street. We also offer great cost effective options along with our great pricing on Magnaflow products.

Baffles are honestly never a good idea as they restrict flow which cost HP. There are better options out there that will give you what you're looking for. Please feel free to call, email or PM me anytime with questions!

It depends on the sound you're going for. If you want it to sound like Magnaflow 16580 then yes, it will give you an aggressive tone and increased performance. It will also help control the decel pop, the x-pipe crosses exhaust pulses which changes the tone to a much more refined sound than removing just the mufflers or the mufflers and resonator(s). If you remove the rear converters or go to highflow's I would recommend the 10791 and (2) 14326's.

Uhhh...since you quoted my post I'm going to assume this one might have been addressed to me. If so...I hope you didn't take anything from my posts that imply that I was not happy or that you talked me into/sold me something I didn't want.

I absolutely wanted the resonated X-Pipe (11386) and the Magnaflow tips that I bought from you. I'm glad I put them on with the muffler delete and I'm also very help with this combo and my rear cat delete. I'm very happy with my system setup and wouldn't change it for the money.

I hope that you didn't read something into my thread that implied anything otherwise.

i have the muffler delete now... Perfect for temporary to wake up that sewing machine... but im going to order the flowmaster catback... cant take the decel pop... sounds like orville reddenbutter is chasing my ass..

[herkman]

I have the Kooks 1 7/8 catted LT's with stock mufflers and I get lots of popping with that combo. I also have the Vector tune so my question is....with a muffler delete, how bad can the popping be? I was thinking of doing the delete.

Glad you did the muffler delete....it's a semi-temp fix for me as well. Although I like my setup a lot. I'll more than likely change mine out once I get LT headers in a year or so.

I would be curious if the Flowmaster system gets rid of the decel popping. My guess is you're not going to see that much of a change. You'll probably get some toned down because of the mufflers and X-pipe but I would be willing to bet it's still going to be there. The popping is there even from the factory...its just that now you have a louder exhaust and you can hear it more.
