Re: drilling a hole in res

I would think that it would make your exhaust have that "pffffffffft pffffffffft" exhaust leak sound. I experienced this on my old WRX when a borla band clamp came loose. Just little puffs of air escaping. It's not a cool sound.

Yeah, that's called an exhaust leak As others have said, just go to a local muffler shop and have a straight pipe welded in. Just be warned that sometimes vehicles sound better with the resonators than without.

Have you seen the Gibson axel back exhaust that people are asking about in this forum? Give it a look. I think I'm going to buy it for my HEMI.

Re: drilling a hole in res

Rpandher, its not that simple on a WK2. There has been a lot of discussion threads here to look back on as this topic comes up often. Plenty of sound clips can be found with some digging.

How do you feel about drone? In your driving style, does MDS kick in often and for any length of time. The less expensive solutions typically sound crappy and, if you do a lot of highway, the drone could drive you nutty. Integrated systems like Corsa or Mopar seem to have solved the drone thing.

Sound is subjective, replacing the resonators with straight pipe sounds like crap to me, axle backs are better but still no joy, but perhaps you are not so picky.

Re: drilling a hole in res

All OE piping is stainless. If your on a budget, keep it, and start replacing mufflers/resonators until you achieve your desired sound.

Re: drilling a hole in res

cut the resonator off and bring it to the junk yard. you'll get like 20-30$ for it.

Re: drilling a hole in res

I had the Dynomax cat-back installed last summer and have tried to learn to "live with it" ever since. Others may disagree, but I think the drone is unacceptable. As if to add insult to injury, the exhaust tips are almost completely covered in rust!

I had the foresight to keep the factory system which may just end up back on the Jeep. My original plan was to go with the Borla since it's gotten favorable reviews here and on other forums, but I opted to take the less expensive route. I guess the old adage is true: you get what you pay for.


So, I'm going back to my original plan and give the Borla system a try. I'll wait until spring by which time I'll be ready to remove the Drone-o-Max.

Re: drilling a hole in res

On the WK2 the resonators are at he back and the are already hollowed out they are empty shells with chambers.

to change the sound you have limited options:
  • Add resonated tips
  • cut the resonators off and add straight pipe
  • Change the resonators
  • Replace the mufflers
  • remove the mufflers
Anyhting thing after that and you might as well just buy a tuned aftermarket system.
