Default QTP headers into - ????

I have a custom ory and slp lm1. At lower rmp this setup is raspy / cackels as you guys probably already know. Just wondering what setups you fellas have. Probably alot of you will tell me to go true duals I know. Is there any other setups or something else I could to to maybe quiet this thing down a bit??? The actual loudness at higher rpms doesnt bother me, just that shitty sound when crusing and getting up to speed.

Custom Y? What kind of merge does it have? I will have find a Y that works with the QTPs and with a tunnel mounted TA w/DSL.

I've heard those "BorlaMouths" before and they sound ******' sweet. I think the guys just replace the SLP resonator with a Borla XR1(?) muffler of the same length. I don't know the lengths though. They do sound awesome though.

I might have to check out some sound clips of magnaflow. this would probably be the easiest for me just swapping exhaust systems and keeping my custom ory.

I had a Borlamouth on my last car along with Pacesetters and ORY. It still rasp but very little. It did drone a bit at certain rpms, then put 2 of these on each header collector and no more rasp and no noticeable performance loss. On my current car I just have the Magnaflow with a catted Y and it is so quiet at idle (no more pissing the neighbors), but loud at wot.

You can hear my previous car here (The new owner is driving it in this video)
