I am going to Germany soon and need to know if there are any tricks to make my car quieter for the inspection when I pick my car up. I have a Buschur TBE/HFC/Magnaflow combo. I have to be under 95db, any ideas?

 

put a resonator in---something straight thru..plenty can be had for a few bucks...length is critical so the longer the quieter.

 

Is it only for the inspection or for the entire time you are driving around?

If it is just for the isnpection, I would say since there is only four bolts on the Cat, just bring a stock cat with you and throw it on for the inspection, then switch back.

 

I just put the stock cat back on my car (inspection time) and it is soooo much more quiet. I'm going to leave it on for awhile.

 

put a silencer on my Greddy Ti and its quiet. And thats with a testpipe and 3" downpipe

 

^^haha!!! that's one funny avatar!!!! Anyway....silencer or stock cat.

 

Put in a resonator right before the muffler. Does amazing things for the sound quality, but it will probably rob you of 3-5 HP because of the turbulence it creates in the exhaust stream....

 

This would work but the Buschur is slip-fit on one side of the cat so this won't work.

I have heard of stuffing the exhaust with steelwhool? does it work? I dont plan on unbolting at all. I will pay them out if I have too!

 

Do you have any sound clips of your setup? How loud does it sound to you compared to stock? This is the exact setup I've been considering, but I don't want it to be too loud. Deep and throaty sounding is okay, but not buzzy or LOUD.

 

The buschur magnaflow catback with a stock cat is very quiet.......even when i put the test pipe on it still isnt "that" loud until you go wot, but even then it isnt as loud as some others I have heard.
