    Default Solo Exhaust with mufflers

    Hey guys, some may think I'm crazy for asking this, but I'm wondering if anyone has tried running a performance cat back through factory mufflers or any mufflers. The reason I ask is, I have a Solo exhaust (I think it's the V1 or V2 it has the T in front of the mid muffleR) And as Solo states "in 4 cyl mode there is a low guttural". That sound is driving me crazy. I LOVE the way it sounds under power, but when normal hwy driving (this is what I mainly do), it seems like it always be in that "gutteral" mode. I have tried to adjust the J pipes, and I can't seem to make it sound any different. Any thought would be appreciated.

    I am running the Solo Mach Balanced mid pipes (same as yours with H-pipe instead of T-pipe). I modified the rear mid-pipes to mate up to the stock axle backs. I have long tube headers from Doug Thorley. The systems is quiet with no drone. It was fine in four cylinder mode too. Now I have a cam with no 4 cyl mode.

    Thanks for the input on the muffler mod, I was wondering when you say it was quiet, was it quiet like stock or did it still have a little rumble to it?

    I have a full kooks system back to factory GT mufflers and it is almost as quiet as stock. Very, very quiet. I imagine it would be the same or quieter for you, depending on if you have the mid muffler and resonators. I have neither.

    A little more low frequency rumble than stock. Most people would think the car is stock. I'm going to make a set of axle backs from Vortex mufflers. I can switch back to the GT muffs if they are too loud.

    I hear that all the time, but I was under the impression to do that you had to change the cam?

    That is very interesting, and this can be done with a hand held programmer like I see on Ebay?

    the cortex will do it, but if you plan on any mods past a intake forget it and get vms/livernois/ or a custom tune.
