I want to delete my mufflers but was told that would reduce low end torque and possible some horsepower. Is this true or myth? Is there a definitive answer?
Hey,I did the resonator delete, moved my peak torque up to 3500 RPM from about 2500 RPM, but it's not really that bad.
Then I added electric cut-outs, right behind the catalytic converters and a bit before the mufflers.
With them open, it's the best sound I've ever heard in my life, but I have WAY less torque until about 3500 RPM when it comes back. It also sounds like my car is yelling at the world for being in its way.
With them closed the torque is back to what it was and the power delivery not only flattens out but is significantly smoother.
I can do back to back A/B tests, bottom line, you lose torque without mufflers.
I would highly recommend the resonator delete though for manuals. I loved it until I got my cut-outs five months later.
If your exhaust is comparable to a 2013 and you're near me I'd love to swap from behind the mids to the rear bumper so that it's stock with the cut-outs closed (cut-outs are installed on the mid-pipe).
I have a 13 auto. I did muffler delete. Thought it sounded a little cleaner and less raspy the resonator delete. I did notice a low end torque drop significantly. Since I wanted louder I put on super 44 flowmasters and did resonator delete. It rumbles now and sounds great. If you don't like drone it will not work for you. The super 40's may be more tolerable. You could also add super 10's at the tip to counter some of that. Either way it will sound like it should!Thanks for all the quick and knowledgeable responses. I think I will just stick with stock exhaust for now since the lower RPM range is where I find the car spends most of its time. I would hate to lose even the smallest of amount of torque. To me, the torque is what makes these cars so fun.
