Gather round my diesel clan
Itís been a busy day today but Iíve managed to fit the new exhaust system, take lots of pictures, take the car for a quick spin and make a few movies.
First things first Ė let me explain why I decided to go with this AlfaTune straight through exhaust system. Unlike petrol engines changing the exhaust system doesnít give the same results for a diesel engine however there are definitely some advantages to be had! The first thing is that this exhaust system is a nice, sensible, stainless steel system - 2.5inch straight through system with a pair of mini backboxes. Itís nicely made as you can see on the pictures and carefully designed for maximum flow. The original exhaust system has lots of narrowing sections and the backbox entrance and exit pipes are offset giving plenty of exhaust flow resistance. Resistance that we donít want on our diesel as it slows our turbo spooling up!
The new exhaust system doesnít have narrowing sections nor does it have offset pipes.
So what does it sound like?
The sound level this straight through system is not louder than standard but it has a lovely deep, bassy, throaty sound to it under acceleration.
When cruising at a constant speed it is still nice and stealth-quiet. I have never heard a diesel car sounding this good before!
You can still hear of course itís a diesel but it sounds much, much nicer than the standard system.
What more do you want?
Apart from the stainless steel, faster turbo spool-up, much nicer sound the other advantage is size and weight! The original backbox weighs in at a massive 7.2kg each whereas the Alfatune backbox comes in at just 3.8kg. Thatís a huge difference!!!!!
I have also managed to record some video footage of the exhaust note before and after. Baby duties took over so the editing will have to wait...
In the meantime here are some pictures I took so far for you to feast your eyes and start saving for Xmas! Santa is going to be generous this year!
