Thats it I've had it!
My exhaust is useless
I have Fast Intentions HF Cats, 05 midpipe and HKS Rear muffler
and it all counts for NOTHING!
every exhaust piece I have added has only made my G slower.
so not only is my car loud. raspy and embarrasing, its slower than a 5.5 gen maxima (which is what I found out just last night)
im returning everything back to stock. Im assuming the ECU has just gone crazy and has retarded my timing. Im not gonna fork over another G to tune this stupid ECU, its a dam money pit and its only gonna stop if I quit now.

my H/F cat felt very nice the night i put it on. every day after that it felt slower than stock.

I too went through different variations of a put together exhaust as well. Coupe middy, HKS rear, Crawford CATs, Megan Racing Y pipe.
I lost a considerably noticable amount of bottom end when I put the Y pipe on and got an annoying rasp (due to 3 inch outlet dumping into a 2.5 inch inlet)..got ride of the Y. CATs gave me a gain on both top and bottom end. (more noticable on top end) but basically only on the top end since I coupled them with the Y. I also had a small rasp from time to time with those as well and I even got all new gaskets from the header outlets all the way out the back.
Sold the CATs and now have whats left.
I don't think your rasp will go away with new gaskets but it's worth a try I guess. The gaskets on the top side of the CATs are the most expensive. The rest are fairly inexpensive.
I am now opting for a full cat back system and will most likely be done with exhaust from there.
I feel your pain Neal as I went through the same. In the end, all these aftermarket exhaust parts don't always match up.
Try just the middy and the HKS, reset the ECU and drive it like you stole it so the ECU learns the new flow patterns.
Good luck
