Got the 159 tbi, now what about sound?

rlb159 · #1 (**Post Link**) 19-05-12

Hey guys,

Just bought the 2011 159 sw tbi and I r e a l l y need to do something about the sound of the thing - I will do a remap in a few weeks to go up to 242 hp (the guys says he might do 250++).

However, sound image is dull, any recommendations that don't kill my ears or budget? I am thinking airfilter, straightening pipe / alternate exhaust delivery - I just want it to sound a little more aggressive....

Any tips well appreciated! :-)

Vroooooom....

Try AHM in Hertford. They have done a lot of work on the TBI engine. I think I am right to say that Turbos kill sound. Sorry, just noticed you are in Oslo!!!

One AOer (Stefan) tried various ways of trying to get his TBi to sound ok but didn't manage it

Alfa spent a lot of money on 'noise, vibration & harshness' testing to get it that quiet. If you change one of the exhaust hangers to cheap rubber you'll get a nice vibration through the shell that will sound just like a new silencer.

Where will you make the ecu tuning? autodelta or alfa tuner ?

Try new exhaust mufflers.. and of course new metallic HJS cat..

I had quite some turbos before, but this one sounds like an electric milk steamer.... nothing. Such a great engine and car, but soooo little noise.

I am not too excited about the cheaper rubber vibrations idea, BUT, new exhaust mufflers are an idea - any recommendations that proove OK?

The remap will be done at a place called Chipsenter - they are purely Norwegian though.. but work with a German IT wiz to create software specifically for my tbi...

air filter will give a nice induction roar.

who cares what the car sounds like when it looks as good as it does...
im sure a decat pipe and new muffler will give it a deeper, throatier sound, and a bit of power. but ultimately the turbo does kill the sound so you might get a loud whistle from the turbo...

still gona sound better than my tractor engine powered 159! haha
