I initially wanted the MAD exhaust cause it was a little more aggressive sounding based on clips I found online. Currently probably satisfied I stayed with this as it's wild enough. Below aren't great comparisons, but it's what I have for those of you debating like I was.

Dinan Exhaust, AA Downpipe and a custom tune:

Stock w/AA Downpipe and probably 93 Stage 1 OTS tune:

Stock with probably a 93 stage 1 OTS and lame revs in my parkade trying not to annoy everyone:

Haven't really had a chance to stare at the back and debate if i like the quad vs square exhausts.
I still don't understand the Dinan Exhaust and its idea to essentially run single pipe. You can see from the video the exhaust is picking the path of least resistance. Essentially only coming out from the far left pipe where the valve is supposed to be.
