I have the AA Catted Hi Flow DP, AWE Touring axleback with their res delete performance midpipe.
After install I found that with the res delete the car was hella loud esp. during cold start - a little too loud for my likes or my neighbors
So I ended up installing an aftermarket resonator in the AWE midpipe & now the sound is perfect
So in hindsight, I could have saved $$ & just used my stock midpipe with the res but it's all an iteration with me till I find that sweet spot
I went thru (3) exhaust systems till I got to the AWE & it has been my favorite & a keeper
Of course I purchased the AWE & AA DP from Mike @ XPH
