Question

Yes. You will lose some torques.

Back pressure is the biggest fucking meme. Dudes run open headers, how the fuck is "back pressure" a thing?

>people on forums said that it might fuck up my exhaust back pressure and fuck up my mpgs
Jesus fucking Christmas

I'm going to be nice because I'm assuming you don't know any better.

It will not fuck with your fuel economy by itself. You enjoying the new sound and flooring it everywhere will fuck your fuel economy.

Unless you touch with your cats, mufflers and resonators are only gonna affect performance.

With a straight pipe at lower rpms you will loose torque, higher rpms you will gain some hp (restriction) any one who says otherwise is a meme. xC

t-thanks but what about muh torque

Thanks brotha. Is the difference in torque noticeable?

>>16073556
You say you're only removing your mid silencer (resonator I'm assuming), and leaving the catalytic converter and Muffler alone?

It won't affect anything noticeable at all other than the sound.

>>16073571
Alright thanks lad, I mean if it fucks anything up I can just put my stock resonator back in.

Depends on the car, obviously if you drive a 4cyl then yes it will be noticiable, you'll probably be redlining first to take off, I might be exagerating but you get the point. There's a reason why even race cars get exhausts (other than noise restriction)

Sure thing m8

Do not listen to fucking anything in this post

removing a restriction increases flow and therefore can create more power. depending on how bottlenecked your system is this could mean better driveability everywhere or only at the top end.

low end torque because of exhaust changes are not because of backpressure it is because of scavenging. the size of the pipe and how much exhaust is flowing dictates when peak scavenging occurs. scavenging boosts torque.

this is why when mexican schumacher puts a 3 inch pipe on his civic he thinks that he lost back pressure and therefore torque. In simple terms thats partially correct but not really true. the stock pipes diameter was tuned to help the engine create power through scavenging.

a 2 inch straight pipe on a 1.6 will most likely create more torque and more power EVERYWHERE compared to a 2.25 inch pipe with cats, resonators and mufflers.

does that make sense?

>>16073626
Yep. I'm going to use stock diameter anyway not 3" or some shit like that
