Perry01, did you find a set of bypass pipes for the 2nd cats? Or did you have some straight pipes welded in to replace them?? Or neither and just adding some wisdom...?
I was going to cut mine out and weld in some straight pipes, but I'm getting mixed feedback on whether or not I'll see/feel a difference when removing them...

|liquidlynx||And it's reversible which is good, but why would you?|

Looks like a quick and inexpensive modification.
Bypassing the secondary cats really helps that V8 breathe better though. It's not cheap but the results are quite nice.

|liquidlynx||Yep, that's exactly right. I didn't cut not anything in the suitcase at all. I did exactly as said, and for about the price and time of a coffee or two at Starbucks the result was great. But the weld design looks awesome too. Both kind of simulate the cat delete and that can cost $$$. I wished to merely pass on the this info for all of us as it was such an easy cheap, reversible modification that will satisfy any Touareg owner. Cayene owners do this as well, and I'm sure the Q7's can also. Anyway, happy to help anyone that may want to try|

|TJay||I don't think liquidlynx actually opened the case, I think he just extracted those skinny tubes from the sides and hammered in a larger diameter pipe which prevented the exhaust from actually entering the case chamber - at least most of it. If you notice in that video, there are tubes with tons of holes in them. I think by putting that 1 7/8 pipe he effectively blocked those holes and now has a straight through design. That said, your set up certainly does look very clean and most people probably wouldn't even know what's missing. Well done!|

Lose probably 45lbs in the rear, get the same sound, and save a couple hours of cutting the case open and having to weld it shut again.
But, to each their own. I did like the video, how you can see whats inside the case. That was pretty cool lookin...

I think the OEM look is still achieved, even without the suitcase there...
From underneath, a pair of pipes welded on there the OEM muffler used to be clamped on...
Going around my air suspension tank...
Hooked up to OEM tips...

|TJay||You're probably right, but I like the idea of keeping it stock looking while gaining a nice sound at the same time...|

Seems like a lot of work, just to keep the suitcase muffler there? Probably easier to just remove from there it's clamped on, and weld on straight pipes to the OEM tips.
Just my two cents...
