its been covered before and after a search i decided to take my car in last friday to have an exhaust done for my project gti as it was completely rotten.
i told the guy i wanted a 2.25" system right through and nothing to loud. i also mentioned that i have heard that a 18" resonator and triple flow exhaust with 2" tip is a proven recipe and would prefer something along these lines. however i had a good second hand round muffler that he said would be ok and decided to use that.
i picked up on friday arvo, drove it home and left it there for the weekend.
it was so loud that it was undriveable i was too embarrassed to drive it. when i had a good look i noticed it has a 10 - 12" resonator and the straight through round rear muffler with 2.25 tip instead of 2" tip
ok so maybe thats my fault for bringing in some piece of secondhand rubbish. mind you it was a stainless muffler in very good condition. cost someone a truckload. or maybe its my fault for not making myself clearer or may he just didnt listen what ever way i took it back to have it fixed and again mentioned that maybe a larger resonator might shut it up. he seemed to think putting a 2 " triple flow rear muffler would be better and the resonator was ok.
picked it up today and it is alot better but still droning very badly. ontop of all this he has sort of butchered it now with a 8 x 4" oval muffler around 14" lg with 2" tip. the muffler hangs down on one side and looks crap.
also he has cut and shut the rest of it to make it all fit in and added a large flange to bolt it all together. in some spots its perfect with excellent welds and in other spots its very rough with some very ugly welds and dodgy looking brakets
so im $350 out of pocket and still didnt get what i wanted.
anyway for all those considering a system make sure you know exactly what you want before you go in and make sure they understand what it is you want.
im now considering taking it somewhere else to be fixed. or maybe take it back and ask for it to be fixed.
can anyone tell me would a longer resonator fix the drone?
PS: i should probley mention its not a loud exhaust it actually sounds very nice but just drones very badly when cruzing. if i could reduce that it would be ok and i would live with the shity welds crappy brakets and crooked rear muffler.
