Complete myth that turbo cars need back pressure, infact back pressure is a engine killer on tuned turbo carsWould you not lose a lot of back pressure by fitting a Cupra exhaust to a 1.5 engine, reducing torque and low end power?
Apologies, as many people I got mixed up with exhaust flow velocity and back pressure. I'm definitely not a flow mechanic expert. I just knew one size exhaust doesn't suit all and bigger doesn't always equal better, even on turbo engines. As you have said back pressure isn't a good thing for turbo cars but every engine wants a high exhaust flow velocity for maximum performance. This is why wastegates exist to offset the back pressure implications of creating a high exhaust velocity flow system at lower rpms. Low exhaust velocity means low turbo spool resulting in lower power.Complete myth that turbo cars need back pressure, infact back pressure is a engine killer on tuned turbo cars
This is a simple job, my mate had his 2.0 tdi fitted with my old cupra backbox with tips on it. Take it to any garage that do exhausts and they should be able to do this for you without a problem. As its a dual exit exhaust, be prepared to spend a minimum of £250. Not cheap at all.
I've already got the exhaust just need it piping and swapping over.
