Hello, I did a search and saw several posts with differing opinions on what I'm sure has been beaten to death as a topic.  I just bought a brand new two-year-old Continental GT 650 that had been sitting at a local dealer and immediately went ahead and ordered a set of the AEW TE201 slip on's based strictly on appearance and size (and the desire for a bit of noise) but didn't take the time to realize that the mufflers on this bike also contain the cats. My question - is it safe to install these more open 'glass pack' type slip-ons without one of the booster plugs or additional work on the fueling system? I know it has been hugely debated if the existing ECU is capable of learning/adjusting fueling to work with the new exhaust set up. Any input would be very much appreciated!

Yes, safe, no problem with mine mounted for almost two years, and a nice sound althought a bit too loud in my opinion



Edit : Sorry, mine are TE101 but same production

Bon soir Voun,
You have a classic workshop with pit, wonderful! Are you working on your 2CV there?

Yes at least in part because of the narrow bore headers and their cats that are the fundamental restriction for increased flow.  Changing the mufflers mostly affects the noise and weight rather than performance especially with the cheaper louder pipe options

And of course increases pollution…

Thanks for the responses everyone - I hadn't realized that the downpipes also contained a cat, which makes me feel much better about this whole thing. Real reason for me was going for the more straight out-the-back look of the AEW pipes. I tested them without the DB killer and also found them too loud, with it installed the sound is really quite good to my ears. Now to get through this break in period when the temps are barely above freezing so I don't need to wait for service in the warm weather!
