Right guys! Basically I drive an A4 B8 2.0tdi (170bhp version) and I'm currently in the process of arranging a few things. Firstly a friend of mine who owns a garage is happy to gut my DPF for me and obviously stick it back on the car (MOT lark i know, i know, its illegal now). Secondly I've got an exhaust guy on standby too to help me fit a quad (2x2) exhaust system. Then finally it will be going for a Re-map and EGR delete at another place. What I've come to ask for advice or help with is the whole set up so i don't get the dreaded drone or a constant pain in the **** exhaust tone when driving anywhere at all! Basically I have grown past the whole exhaust making my car as loud as possible stage! Did that with my ST when i was a teen! I enjoy my A4 as it is right now where i can drive around town and it is smooth, pretty much quiet (its a derv so it does make noise as we know) and motorways it just loves them, again, smooth and pretty much hardly any noise or drone. I know some will say well leave it as it is. I don't wish to do that as i want the exhaust quad tips look, the DPF gone so its an incredibly expensive part that i don't need to worry about going at any moment, the car will run and breathe better without it and I want the EGR delete because it keeps playing up for me (errors all the time on my vagcom). Right, so now we know i deffo want to do this, what is the best way to achieve what i want which is: - All the looks - DPF issue a thing of the past - More power and smoother driving mixed with better mpg with a Remap - Not a chav-tastic Corsa like noise coming from the car/exhaust (other than a nice subtle tone or grunt when flooring it i guess as it is to be expected) My original idea was to do this: - Gut the DPF - EGR Delete - Remap - Keep the centre silencer in place (some models i have been told don't have one but mine does just after the back box a little further down) - Do i remove the back box already in place as it doesn't help the breathing of the car really - 4 lovely tips on the end of the pipes ...... Taaadaaaaa!!! Now i was wanting advice, tips, videos, links, anything from anyone who may have done this or similar themselves with a diesel and to see how it sounds and drives. The exhaust is the main thing I'm after, like i said i don't want any drone, constant noise in the cabin/inside and little noise when driving normally like everyone else around town or on motorways! When i floor it i am not daft, i expect some noise! Thanks guys, appreciate any help and appreciate you taking the time to read this novel!
