Why You Should NEVER Straight Pipe Your Car

Показать описание

Straight piping an exahust system might seem like the fastest way to make your car have more power, but also more flow. That might have been the case years ago, but technology has come a very long way. Today we stop by Magnaflow and test out the theory of straight pipe exhaust vs an actual developed exhaust system and see the flow results. We also compare and contrast different exhaust as well and how it effects tone and performance. So let's get to it!

Disappointing the burble tune owners everywhere.

The problem with Borla, Flowmaster and Magnaflow historically is they have never addressed drone until pretty recently. It’s good to see them address it.

In the past, Corsa has really only been the one to directly solve drone while giving you increased volume.

Sometimes even modifying the stock systems have a better outcome than older Borla/FM/MF systems as far as brain-rattling drone.

The issue is most people who run a straight pipe are broke or cheap. One lesson, my dad taught me with project cars. Just keep it stock until you can get the nice part.

While this is really good information, I personally like the sound of my straight piped new edge. Makes me smile every day.

I wouldn’t ask a muffler company performance questions in regards to muffler vs. no muffler lol. You might aswell be asking the epa. Every popular ford and gm tuner would say to do straight pipe/catless/dumps… whatever the least restrictive setup your willing to run, if you want all the power. The volume is a side effect, not why they’re doing it.

I heard a grand total of zero backed up claims... Gotta love a muffler salesman convincing you you need a muffler hahahaha

Since this isn't an ad I can say Borla 10x better quality and sound AND customer support than Magnablow.

Good video but there was zero discussion on power output.
Steeda did a Dyno video and sound comparison using decibel readers and it was very informative. Throughout the history of the Gen 3 Coyote S550 Mustang we picked up more RWH with the X pipe over the H pipe. On the S550 we saw minimal 3 RWH Gain on the H pipe and deeper tone and the X pipe 10+ RWH gain and more raspy tone.
But now on the S650 Gen 4 Coyote Mustang Steeda found just the opposite results. 1-2 RWH with the X pipe still being louder and raspy sound but 10+ RWH gain on the H-pipe and much improved deeper bass sound also. Hence the Pennsylvania company AWE Switchpath catback system with included H pipe puts out better deeper sound and 10+ RWH. Same results with the Borla S type switch path exhaust both companies allowing the valved exhaust option so you don’t give up the expensive option Ford AE exhaust. I have the magnaflow exhaust on my Ford F-150 but when my Dark Horse comes in I will be buying the AWE Switch-path exhaust which provides an increase of 10 rear wheel horsepower and a better H pipe deep sound with the gurgles and pops as you down shift. Still would like to hear if the magnaflow picked up any
Cheers ‼️👍👊💪🇺🇸🐎

The problem is the majority of the cars on the road that _are_ straight piped shouldn’t be; V6 Chargers/Challengers, CVT cars, Audi A4s, 330i’s, even Type Rs. Turbo cars with straight pipes sound the worst, they should like literal wet diarrhea.

But the sound when you straight pipe a stock 5th gen Camaro SS is amazing.

Knocked it out of the park on this one🤘

Great content David! I have really liked the way Magnaflow systems sounded on my cars but it was cool to see the engineering explained behind the design and the thought process they put behind it all. Straight piping sounds too much like a desperate shreak to throw a rod and drones way too loudly even when far away on so many cars so I would never want to do it. Knowing how Magnaflow used the perforations in the full body mufflers to break up the exhausts laminar flow and actually unlock more power makes my favorite exhaust choice even more worth it.

Magnaflow will make even a yaris sound good. I used the two mufflers that were in the beginning of this video on my custom 2 inch exhaust. When I started the car for the first time it was music to my ears. It gave the 1.5 a smooth deep tone all across the rpm band. Magnaflow is the best muffler manufacturer hands down.

mrpartridge

can't deny Magna has the saxxiest and most robust muffler bearings. Witness the greatness at exactly the 45 second mark. @0:45

Magnaflow has always been one of the brands you go to for quality. Not my cup, since I mostly just drive chitboxes, but it's definitely the good stuff.
