So today was the day I had the changes undertaken to the quad.
Heres the before picture:
So basically the old quad conversion was removed and packaged ready to be shipped to its new rightful owner.
So on with the new system then... Changes were made due to the system not sitting perfect with the carbon fibre diffuser and causing an annoying buzz now and again as it touched on the underside of the diffuser. So whilst having the rear section re-made I decided to make some alterations to the system. These are as follows
Decided to do away with the t piece section arrangement behind the rear bumper and pipe each side up straight from the mid section. Basically the existing system was cut back to just after the mid silencers. We then added in 2 booster type silencers straight after the exisitng silencer and then split the pipe around the diff to either side of the car.
A rear silencer was added to the LHS where the originial silencer used to sit; however it was not possible to get one on the RHS due to problems with the battery as covered previously on the forum may a time. I didnt want to go down CJ's route as good as it is in re-routing the battery. Basically the RHS is piped straight from the new booster silencer at the mid section to the exit pipe. To do this meant the slight relocation of the charcoal filter to enable the pipe to sit in the desired location.
Now to the final bit and probably the bit which will cause most debate on this forum. I decided that as I was changing the system to go for a different look. What I didnt want to do was go to this effort and expense for the system to look exactly the same. I've always been the kind of guy to want things to look different after spending money. Makes the parting of the cash somewhat easier I find :roll: I don't recall seeing this type of exit pipe on any Z4 and quite liked the look of it. It just seems to suit the rear end perfectly with the CF diffuser. Looks so more aggressive than the previous set-up.
So I have attached some pics and would welcome any comments positive or negative. I know this is either a love it or hate it look.
Just to sum up the changes, the exhaust note has changed quite considerably. It's alot deeper sound, less raspier but the car seems to get quieter the higher the rpm and intrusive noise into the cabin at around 80MPH has been reduced which is one of the things I wanted tweaking with the system.
Obviousy the system will need to bed in again and will only sound better the more miles and soot that are put through it. Over all I'm very pleased with the outcome... cant help thinking a few flames wouldnt look out of place coming out of the pipes now and again

Really like the DTM style up-swept tail pipes and diffuser on your car, would like to see a photo directly behind, but from higher up.
