1. Still struggling with my exhaust... got straight pipe on my fabia vrs and was thinking what to do to get that noise when you release the accelerator pedal.  I know its about backpressure.. but never had this noise even when deleted cat and left back box and after removing both. any ideas? I know some boras got that sounds when changing gears but it doesnt sound like diesel bov . thank you!
 

 

I got another question ... now about the turbo flutter sound... is that something to do with backpressure too ? I seen a video when someone fitted a sport filter to a corsa which is diesel and got that sound . most of people call it induction noise. some people say its bad for the turbo because air goes back through turbo because of bad pressure and some of them says that its good to have it instead of bov when car got loads of power. Where is the truth? any possibility to do that on my car? ( got egr delete) and if it's worth doing? 
I had that sound before but only when reving and turning ignition off . Since I done straight pipe the sound dissapeared. thanks alot!

 

Oh boy, so a SEAT Leon 1.8T is a PETROL turbo, the turbo works totally differently to a diesel turbo which is why it sounds completely different.

 

You made your tractor louder with the straight pipe so now you can't hear the turbo and you can't fit a BOV to a diesel without ruining the performance.

 

You can't have what you want unless you buy a petrol turbo car.

You don't need a petrol car. What you're after is called a 'mufflerectomy' if I'm correct in assuming, no cat and backbox will give you the good sound, not sure why you're not getting that sound if youve already done it

Diesels have no throttle plate so have no need for a diverter valve hence no fast and furious sound effects.

There are dump valve simulators you can fix in the tail pipe for under £10 or electronic blow off simulators complete with speaker but more pricey. Ebay is your friend.

Not as loud as what?

 

Don't laugh, it's not funny, this is serious.

 

Which Bora?
