Started a thread discussing the differences between Mk5 Jetta and GTI exhaust systems, which was lost when the forum went down. So thought it may be worth starting another since a search didn't bring up much information on here.
I would like to increase the noise of the factory system on my Mk5 Jetta Turbo DSG, making it a touch louder and also increasing volume of the DSG 'pop' in between changes. Hoping to get a more prominent note without being over the top and droney.
VARIATION's between Jetta & Golf Systems (from a quick look underneath mine and a mate's GTI);
- From front of car not far after downpipe, BOTH cars appear to have the same cat converter - is there two in the system? (i.e. one in the dump also.)
- Moving back just before the rear axle on the passenger side, the Jetta has a large muffler (similar style to the rear mufflers on both cars), where the GTI has a much smaller circular 'hotdog' style muffler.
- Continuing to the rear, the Jetta has a second large muffler situated on passenger side only, where the GTI has a long but thin looking 'briefcase' style muffler almost stretching the width of the car below rear bumper.
Piping diameter seems to be the same, so I'm putting the fact that the GTI seems quite a bit louder down to the variation in their exhaust muffler/resonator set-up.
A few questions;
- Has anyone done or know of people deleting one or more of the mufflers on a standard system? Would there be any performance gains or would you be better off replacing with a smaller sports muffler?
Corrections, Comments or Additional information welcomed on above, so this can become a good reference for anyone looking to do exhaust work on a Mk5 without simply purchasing an aftermarket item.
