morning guys..... i had the turbo back 3" non res system with the sports cat fitted yesterday.
i took the car in to the garage and got chance to check out the system before it was fitted.... the welds were all very neat and no stress on any of the bends whatsoever.
i left the car expecting maybe a 2 hour fitting time but due to the original exhaust rusting up they had to cut most of it off and wrestle with the bolts. They said the turbo end was a pain to fit but the rest was not a
problem at all. The only other slight thing that you may want to watch out for is that the back box is a bit tight to the rear bumper but a couple of spacers were put in and it sits very nice with no knocking even over this country's awesome flat roads!!!!
Now to the main bit.... noise....
starting with the potential cabin drone....... one word.... NONE!
all the noise comes when on throttle but at 70-80 there is the smallest of rumbles from the back box but i would honestly say stock systems are very close to the same noise.
The out side noise when on full throttle is absolutely immense.... it is not overly loud to attract unwanted attention but sounds very very nice.....
on tick over there is a very deep nice burble and when you pull away you dont get old grannies dropping to the ground thinking there is an air raid coming back in!
i have a very poor quality interior video that i will try and upload and at some point today i will be able to grab a mate to video a proper one with a decent phone/camera.
hope this helps guys
