So I deleted my muffler and resonator and it sounds really great but the problem is that my car feels a lot slower. Sometimes, I would gas it and I would hear it rev but the car will slowly speed up. Is there a solution to this?? Please Help!!!
Thanks

I know this is irrelevant to your problem but i was thinking of deleting the centre resonator if you could make of a video of what the car sounds like that would be nice! As for the loss of power i believe it has something to do with a loss of back pressure.

If you delete the centre "resonator" which acts as a collector box, you must add an X or H pipe if keeping the mufflers near the exhaust tips. One of these is valved to maintain back pressure, which will cause problems if you run straight pipes. Not to mention CoD issues. Plenty of posts/threads on this if you search, particularly in the C7 S6 forum.

Check out my link with the y pipe installed. No loss of back pressure.
