Muffler Delete = loss of torque? Myth or fact
Hey guys I have been doing a lot of research into a muffler delete for my 2017 Camaro RS, and have seen many things about a loss of back pressure which takes some of your low-end torque away. Can anybody clarify this for me? I am planning on deleting JUST my muffler and keeping my resonator and cats. Will I lose any torque, throttle response, etc?
*CONCLUSION* Hey guys I went ahead and did the delete, and it sounds great! I also have noticed my acceleration is a bit quicker and I feel like I have MORE power. I also have ZERO DRONE. So if anybody is iffy about a delete, do it. You won't be disappointed. If anybody wants to hear what it sounds like or have any questions let me know.

Myth. Must be a V6 community thing because Ive heard other v6 car people talk about this.
In all occasions those who as access to a dyno proved no loss in anything. |

I THINK the back pressure theory is a confusion of a loss of exhaust velocity and scavenging. Most of the time this has happened, it isn't the loss of restriction that causes a loss of torque. The pipe diameter is increased, which increases volume in the exhaust pipe but reduces velocity. The air slowing down at low engine speeds could reduce low speed torque but that increased volume may also lend itself to more top end horsepower due to the increased volume of the pipe. BUT, this is all about combination. Matching your exhaust to your engines needs is the best route to go.
But no, as already mentioned, the cats are far more of a restriction than the muffler. Backpressue isn't good but air velocity/volume in accordance with your engines needs are.

I've seen losses on dynos with new, bigger exhausts put on stock motors where it was intended for modded/higher rpm use. The reason is less scavenging at lower rpms due to lower velocity and/or a different design that is intended to work ideally at higher rpms. Simply removing a muffler shouldn't be an issue.

You’d not lose enough to notice anything. But if you are talking about replacing the muffler with a straight pipe, please don’t. Your Camaro deserves better. Straight pipe muffler deletes sound like pure and complete ass. Plenty of better options.

I think the back pressure deal applies to 2 stroke engines like a dirt bike. Not so much 4 strokes like a car engine.

What would be your suggestion? I don't really want to spend upwards of $400-$700 on a borla or mrt exhaust which imo doesn't really make that much of a sound difference to warrant the cost. I can always have the muffler welded back on as well. Just wanted to try it out
