I was surfing youtube last night and came across some video's of people with 4.2's that sounded mean. Deep thoated exhaust that was loud but sounded more like a cobra mustand than an audi. Some of the guys were cutting out the mufflers and going straight back to the tips. Does anyone know if this is a good idea or are there other inexspensive ways to make it sound that awesome?

 

cut the muffler and put x-pipe, it will sound mean.

new to tha audi scene and prolly a stupid questian. What's an x pipe?

 

An x pipe is where the pipes comes together and creates and x somewhere downsteam in the exhaust. I don't remember exactly what the benefit to this is though.

 

There is no benefit exept the sound, if u have dual exhaust , you crossing them and you get sound like that, this some video of my exhaust system:

and i thought this exaust from awe sounded pretty sick as well

i think as long as youve got the cats on it'll be ok but i could be wrong; probably be a good idea to search around and double check

 

I would suspect the X-pipes either allow the pressure to balance better between the cylinder banks or allow exhaust gas to escape in case one of the pipes gets somehowplugged.

Don't be amazed if, after you rip off the mufflers, your A6 a) doesn't run as well, b) gets worse gas mileage, and c) throws codes. Among other things, mufflers provide backup compression for the engine.
