Just got back from the exhaust shop, i swapped the slp resonator for a round 14" magnaflow, the slp sounded very good at idle and WOT but the partial throttle had some unwanted rasp and even if i dont use my truck much it just gets old. Now the magnaflow so far is a whole lot quieter at idle and WOT but the partial throttle is perfect with zero rasp. Overall im happy but i really wish the magnaflow could be a little more louder at idle and WOT, maybe it will after it gets a few hundred miles on it.

 

My experience with mangaflow mufflers is that they gradually get louder. I have replaced mine 3 times cause it kept getting louder

Currently i have a 5x18 round and 5x11x22 oval in series. I like the way it sounds now

 

I hope it gets louder aslong as the rasp stays away...

 

I never problems with rasp with any of the mangaflow muffler i have used

 

Which round one did you get? 4, 5, or 7" round?

I just put a 4x14" round in front of my 22" si/so magnaflow and it is still too loud around town and screams at WOT. Probably going to 6 or 7" round depending on how much clearance I have under there.

 

when i replaced my little borla xr1 with a magnaflow 14" case. i thought i had messed up because it was waay to quiet, but after a while of driving on it its what i would call broke in and sounds about perfect for what i wanted. also no rasp as mentioned which is great
give it some time before you completely make up your mind..

 

It is the 6" round, #12619.

Im surprised yours is loud though with the 22"?

 

Yup it does get louder after a while

 

So is the 12619 your only muffler or do you have it in a series?

Yeah, me too

 

Yeah its the only muffler on there. Maybe yours is louder cause its a SUV and is under the cab no matter where you put it?
