I searched and never found one straight answer. Do our cars need back pressure for torque. I know some people have said back pressure-bad. But some have also said, again, it helps on our torque which is what are 2900lb cars need. I'm wondering this because i plan on maybe stripping my exhaust off or maybe just my cat. So please, someone who knows these torquey(sp) engines and not just V8's please help-a-brothera out.

Yes N/A engines need to have some form of back pressure for torque.
But a turbo engine needs as little backpressure as possible.

thank you. But I'm wondering now, would cutting my exhaust of at down pipe screw my torque or would it still get back pressure from the exhaust mani?Horsepower sells cars, torque wins races.Comment

No the exhaust manifold has very little backpressure (in comparison to the whole exhaust)

Could you suggest a way for me to keep as much BP as possible and still free up some power for high rpms?Horsepower sells cars, torque wins races.Comment

if you mean just running your car just from the downpipe, that wouldnt be good and youll lose toque for sure.Originally posted by EXkidd91Comment
