Tuning developments have so many different combinations of exhausts, it can be hard to find exactly the sound you'll get.
They do UEL and EL manifolds, non-res, res and super res mid pipes, and a res or non-res back box.
I went for the UEL, super res midpipe and res axle back. As videos from other users were abit too loud for my taste, and i hate rasp.
Here is a video of my setup, sorry for the bad filming but you get an idea for the tone. No drone etc.
Another positive of going TD is that their turbo kits bolt directly to their manifolds, so you wont need to buy another set of headers if you do decide to go turbo further down the line.
20BHP increase top end isnt going to blow your socks off but with UEL i had 35bhp increase in the midrange where the torque dip used to be, and it made it feel much perkier through out. Never really heard much in terms of anything being unreliable after the install.
