So I'm pretty set on getting a True dual under axle setup once I get my Pacesetters on. Through searching I've come up with a few things. Cats will be right after headers, and I'll also be going into the x as soon as the pipes come togetherafter the 45 degree bends. I'm going to try to only use 45's or less.

-Cats will be magnaflow 7.75" long 3"id from ead p#59959
-X-pipe will be summit 3" universal x-pipe kit p#sum642130
-System will be band clamped collectors to cats, and piping before axle

My questions are;
What size magnaflow muffler will fit best behind the bumper. I've heard of people fitting the 6" mufflers back there but what length will work best? I'm thinking the 6" diameter and 14" long magnaflows summit p#mpe14619. Not sure if longer would be better.


Also. Should I try to tuck the x-pipe inside the tunnel brace or will the collectors still hang lower than the x-pipe if it wasnt tucked under the brace? I don't plan to lower the car so I'm thinking I'll be okay.


I'd like a tame, but most importantly, free flowing exhaust that won't get me pulled over all the time. Any help appreciated.

 

I wanted "tame" as well and thats why I went with the Spintechs. They are fairly mild at idle and loud as hell WOT. However, it is still pretty loud inside the car if thats going to bother you.
I have a couple pics on my FQuick that might give you an idea of how much room is back there. I can get some updated ones if you want them. Theres a crappy little vid as well.

On a side note, I will be scrapping the under axle deal and dumping it in front like everyone else. Anytime the axle can unload enough it makes a loud bang which sucks and theres really no way to get around that.

 

youre the first ive heard say they disliked the under axle. I'm going to try it out. I really just wanted to see if the x needed to be in the tunnel brace but the only one i think I've seen is the bassani and I know i'm not getting that tight. Also how long mufflers should be. Thanks for your response.
