It is possible you lost some low end torque. Dye to creating such a short path for the exhaust gases.

Not only possible but it is very likely you lost low RPM torque. With such a short exhaust, you are eliminating the back pressure the engine needs for best performance. Similar to running "open headers". Loud as **** but not as fast on the street. Track cars are tuned to that, your vehicle isn't.

So, there is a solution to have loud sound and same performance?

At least keep the length of piping the same. You will always lose some low end torque when removing mufflers

Ok
Well, i will close the cutout when I go normally and open it when I want more sound
Thanks

Just close it when you are driving normal for best torque, when you wanna be all noisy and such open it up! Im doing the same soon, curious if you used a kit

 

[mimble]

I'm sorry
What do you mean?
Kit of what?

Just to clear things up NO vehicle needs backpressure to run properly. Back pressure is always bad when it comes to performance, the more exhaust you can push out the better it will breathe, yes you'll lose some low end torque because you just changed the power band where your power comes up higher on the rpm band. Factories will always tune a vehicle for low rpm and city driving where low end torque is more efficient than higher rpm power.

This is true. But unless you have a race truck. You want SOME low end torque. Lol

I agree with you, for my daily driver for sure!

Pretty much what I wrote but thanks for clearing that up.

Oh ok, sorry if I jumped over that, just making sure people get a clear idea

All good. Sorry, I was drinkin'.

Thanks to all
But there's nothing to do to have this sound and the same performance?
