Hello guys,

I have an Ark Grip cat-back on my 08 G35 Sedan, I love the sound it makes from the outside and the sound it makes at WOT after 4k rpms, but my normal commute between 2-3k rpms and light throttle is killing me.

I wish it had at least a flutter sound to it but its just a solid low bass hum drone sound. I've put a bunch of insulation in the trunk to try to minimize it but with no effect. I love the look of the exhaust and the performance it gives, but I guess I'm just too old

I really want to keep it, will it help if I put back the stock Y pipe?

Drive around in fifth gear?

Factory cats still in place?

i thought it sounded great with oem cats but agree just got too loud for my taste when matched up with HFCs...
