Need Help With My Exhaust

[LouLou]

Hey all,

I really need some help regarding my exhaust.. I currently have a 3inch BOS importing dump pipe which did connect to the exhaust which i have posted in the pictures below (4.5inch tip). Due to EPA i took off the catback and just replaced it with the stock system without changing the dump pipe in order to clear.

I was just wondering if you guys could point me in the right direction as to how and who could modify my exhaust to make it a reasonable dB without losing too much performance as it is way too loud at the moment.

One more thing, ever since i got my new dump pipe installed this crackling sound has started.. it has been coming from underneath the car. Used to happen a little bit when i had the stock dump on but now it has gotten worse and i cant seem to get rid of it. It comes when im accelerating at low revs and when i take my foot off the accelerator.. Anyone have any idea what it could be?

Thanks in advance guys.

Alan.

put in a mid muffler/resonator. wont restrict more quieten the exhaust

Resonator/muffler or move to qld

Is the noise more rattling or what? have tried to replicate the sound at idle with bonnet up to see where the noise might be coming from? Could be a number of things leaking gasket, loose nut/bolt, wastegate not firm up against the housing, contact between heat shield and dump pipe etc.

Its more of a crackling sound than a rattle.. Lifted the bonnet up and gave it a rev and its coming from the right side of the engine where the turbo is but im not positive on what it could be. Im thinking it could be a leaking gasket or something.

Try grabbing the actuator rod with pliers and pulling towards the front of the car, sometimes the actuator can loose a bit of tension and make a similar noise. Also check everything first because the last thing you want to do is go to all the effort of taking the turbo off to find the gasket is not the problem.
