Hi all, I'm after some advice regarding exhaust systems. The car is a 2.0 TDI 140 PD engine (BKD) At present the exhaust system is standard however it is blowing on the middle section and the rest looks fairly rusty.
I'm thinking rather than patch the exhaust up with standard bits it'd be better to simply rip off and start again.
After speaking to a couple of exhaust fabricators I have decided to go ahead and have a custom exhaust made up in mild steel including a decat The next option is whether to have a backbox put in or keep it a 2.5 inch straight through system off the turbo. Will this be too loud? What are your thoughts, good and bad opinions welcome!
