Mufflex Muffler Bypass review

Hey guy, just wanted to do a quick review on an exhaust i just put on. Theres a small company called mufflex based in PA that makes simple bolt on muffler deletes for a lot of cars out there.(Will place link to the product at the bottom) They make a rear muffler/resonator delete pipe for our srt's. They are around $300 and are made of 309 stainless steel. The installation is super easy, just un-bolt the driver side rear muffler and cut off the passenger side one ( I used a hack saw) and then bolt on the deletes and align the tips. They are real high quality and luckily they include super detailed instructions. the package includes two 5 inch tips similar to the bola attack tips. Now for the sound, these deletes sound perfect. they aren't raspy or high-pitched, they give a really deep clean tone with a good volume. If stock is a 3/10 these are an 8 or 9/10. For interior drone, there basically is none in MDS mode or even under normal cruising. Only a nice crisp rumble. A lot of people who don't have this will tell you that with these deletes you loose back pressure, well thats not true i got the exact same zero to 60 time with this system as stock so don't worry about that. All and all this simple, cheap, and high quality delete is a must have for our jeeps and you literally can't go wrong. i had the corsa before this and absolutely hated it. let me tell you as someone that actually went out and spent $1800 on an exhaust system and hated it that no other system out there (excluding GT Haus) is worth it when there is an option that gives a louder, cleaner, deeper and drone free sound. If you want a perfect sound for your jeep and also want to save some $ then buy this system, you can't go wrong.

PS*** after about 20 miles with these deletes on (being completely pleased with the sound) i decided to move the springs on the stock exhaust valves so that they are always open. All this does is make the idle alittle louder. It also makes the MDS drone alittle louder but its more than bearable. Just to clarify, before i opened the valves i was completely satisfied and there was no drone. Opened them for the hell of it and loved it even more and can deal with the extremely minimal drone. Thanks for reading hope this post helps all of y'all save some money and avoid spending $700 and up for bola and other systems.

Thanks for the write up. From the videos, they sound great and you can't beat the price...even shipped to Australia, $440 delivered.

Thanks for this, listening to the vids it seems like a nice tone and look. I know it's much louder outside, but how much louder is it in the cabin? Do you feel like you have to talk louder to hold a conversation or turn up the music to hear it?

Asking because I've had loud exhausts and after a couple years I find myself wanting a quiet cabin when cruising on the highway. I'm all for loud and crazy under throttle, but have grown to appreciate the quiet cabin in the SRT when cruising.

Thanks

I mean like i said with the exhaust valves still in their closed positions if you dont choose to modify them like i did the drone and sound in the cabin at highway speeda is non existant. Same as stock if now quieter (idk how though lol) but even with the valves held open although there is a louder cruising sound but i kind of enjoy it lol but keep in mind im young and really dont mind loud anoyying sounds they dont bother me. But if you plan on just installing these deletes and not touching the valves on the stock exhaust you will have a quiet drone free cabin when on the highway and when ur just cruising.

Thanks for clarifying, I am sold on this. I talked with Mufflex and they said if it ends up being too loud I can slap an easy seal clamp on the passenger side and be back to stock.

I might try and figure out how to use the stock tips for a stealth look. It almost sounds like a hellcat with the res delete.

Re: Mufflex Muffler Bypass review

Want to say thanks for the post and videos. I loved the sound. Turns out Mufflex is actually located in Trenton NJ which is 25 minutes from my house. Called and they were in stock so I went this morning and picked up a set and installed them today. All I can say is wow. Very impressed with the results. I have heard borla attack...corsa...etc and yes they sound ok but I can honestly say I think this sounds better. My choice of exhaust would be a gthaus setup because of the valves....but $3k....not worth it to me. Under $300 for this setup and I am very pleased.

Re: Mufflex Muffler Bypass review

By the way I have a RIPP supercharger setup and run pretty consistent 3.5 0-60's. Did a before and after test today and exact same results. Both were 3.5 but the after run could probably be heard from half a mile away lol.

Cruising in the cabin it is just slightly louder than stock at light to moderate throttle. No drone what so ever. Heavy to WOT is a different story. Sounds like a fire breathing beast. I am going to try and get a video today and I will post up later.

Re: Mufflex Muffler Bypass review

Good to see another option with 5" tips, but too loud for me. My Borla S is plenty loud...thanks for the review though!

Sorry, are you saying that this sounds louder/on par with the Borla S ?

Probably quite a bit louder considering it is just straight pipes whereas the Borla S has mufflers.
