cut out?
 

bought my 98 A4 Z28 with K&N FIPK and some Flowmaster stickers. What kind of exhaust do I have. I asked the GM service to look at it and tell me what he thought and he said there was a straight pipe and no mufflers BUT it looked like professional work, quote " it's not like someone just hacked off the muffler " Any guesses as to what his is. It is very loud, actually at times interior wise too loud. I have chrome tips 3 1/2" and the CATS are still there. NO MUFFLER at all.

It could be straight pipes if you say it's really that loud.

It could also be a Loudmouth system, especially if it's kind of raspy.

after the ypipe is there a resonator....

my guess is that its a loudmouth

yea. I think so
 

there is a straight pipe out then it splits and on the passenger side there looks to be a resonator. the other pipe weaves towards the driverside then out to the tailpipe. I know it sounds crazy that I don't know what exhaust system and to top it off he has these Flowmaster stickers on the FIPK and on the rear windows. Thanks

do u know what a y pipe is????

how does it split????
does the driver side run header to exhaust tip or they meet at the ned of the y pipe which is right after where its smashed in on drivers side.....then seperates right after axle.......

make sense?????

YES, thats it...
 

NO, I'm less then novice here, BUT you described what I see with the drivers side pipe and it seems to be 'smashed then continues along to the tailpipe. I tought it was a Y-pipe but the Service tech described it as a stright pipe. And there is what looks like a resonator on the passenger side pipe. I seem to get more then enough backfire from this also. Especially whe I hit 50-60 mph and let off the throttle...Thanks for this info, I am just trying to understand what the previous owner put under there! The FIPK was self explanatory from view....

ya its loudmouth im almost positive
