X pipe question
I was thinking about putting an X pipe with cat delete on my 2017 grand sport for a little more sound. But I am concerned that the exhaust will have the strong oder with just the primary cats. Has anyone had this happen with just the primary cats on?

I smell nothing different before/after my Corsa Xpipe swap. Now, not sure if the guy losing the race smells anything different behind me, but I certainly don't. 
Obviously it takes a couple days for the oils and stuff to burn off the new pipes, otherwise all good

I just put the Borla X pipe on mine that deletes the secondary cats. Aside from a little extra smell in the morning before the primary cats warmed up, there is zero odor. The Primary cats do a great job. No need to worry about any smells.

No difference in smell. Most of it comes from the primary cats. I have deleted the secondary and no hint of gas.

As someone else sorta pointed out, you will get a very strong smell of the oils/coating of the pipe for several drives of going thru the heat/cool-down cycles. You'll come to a stop & you or the guy next to you might think somethings burning under the car for a short week or so!
I also wrapped mine with heat tape before install & some of the smell could have been more from it tho.

Yeah no problems here either with borla x pipe. You will notice the biggest sound difference under hard acceleration. I also pulled fuse 42 if you have dual mode exhaust which will leave valves open all the time.
