Hmm...guys have removed the mid resonators with good sound results. Maybe its the piping diameter thats causing it.

 

Maybe a bad weld too?

 

All your paying for is sound when it comes to an exhaust. The biggest gain is removing/bypassing your cat 8 to 15HP can be gained depending on other mods.

On the 1.8T and even 3.0 when the resonater (what you call a mid muffler) is removed it typically makes the exhaust sound canny or tinny. Either put it back on or add a Cherry Bomb to resonate that canny sound. Cherry Bombs can be found at your local auto store or muffler shop. They are cheap muffler/resonators and will last as long as you have your car. Unless you live in the East.

Here is a Cherry Bomb aka Glass Pack. Fiberglass packed straight pipe.


You can always bycass your cats with these too but I been seeing resonators on eBay with threaded taps for the 02 sensor.

 

Cool! Any suggestions for the rear muffler?

 

There are a lot of different ways you can go w/ rear muffler. check out borla's site, magnaflow, millitek, remus, all make good product for our cars.

 

i have no resonator with a remus muffler. I get that tinny/buzzing sound too for awhile, but once the car warms up it goes away.
