Real Posted 01/02/13 12:33 AM Share Posted 01/02/13 12:33 AM Hey LadsI'm looking at doing a Centre/ Rear muffler removal to unleash a little bit of noise! So. First, Centre muffler..What would you boys suggest to replace this with? High-flow pipe? Hotdog? etc... thoughts and opinions? Secondly, Rear muffler..I'll be running a straight pipe here for that nice deep noise/ back crackle we all love! Please feel free to add anything you want to say, or offer any advice! The car goes in next week wednesday for the centre/ rear.And in 4 weeks for a tune.Cheers Link to comment Share on other sites More sharing options...

I would probably try this first before doing the centre. Just because of the positive feedback I've read. Benny. Link to comment Share on other sites More sharing options...

I know N/A cars are fine but with a super charger? Link to comment Share on other sites More sharing options...

Real Posted 02/02/13 04:18 AM Author Share Posted 02/02/13 04:18 AM I believe anything with forced induction (supercharger/ turbo) needs re-tuning after re-alterting the AFR, eg. through cold air intakes/ intercooler and exhausts. So yes I believe you will need a Re-tune.I got the car going in monday morning 8.30am to have the rear muffler taken out and a straight pipe to be replaced, and then the centre muffler to be taken out and replaced with a high-flow centre.I'll post a video of it all when it's complete Then just need to sit tight for 4 weeks till I get my tune done Link to comment Share on other sites More sharing options...

Real Posted 04/02/13 10:41 PM Author Share Posted 04/02/13 10:41 PM Hey Boys,So heres an update.Had my exhaust played around with!Ended up just doing the rear muffler delete as well as deleting the centre muffler.They added a straight pipe into 3.5inch tips.It actually sounds ridiculous! Anyway, here are some pics! I'll get some vids up soon as well after work today (ps. excuse the dirty state of my vehicle) 1 Link to comment Share on other sites More sharing options...
