what did you use for the isr mod

 

The pvc caps and some fuel hose, and the hose barbs - black paint

 

I did the ISR mod with a simple pvc screwon endcap, worked really well and took all of about 15 minutes. Course I havent painted it yet, not that it matters to me.

 

I have an imco in my toy....with the 4cyl it delivers a nice deep tone, not ricey at all!! I had them build it custom with 2.5in pipe all the way from the cat back. I put a 3in black chrome tip comming out just under the bumper (which I am having them cut off this saturday, because I keep hitting the ground when I go off road and it bends and dents it). I really like the quality, the sound and everything...it is kind of loud though, but not F350 loud.

I would go with the IMCO and get either 2.25 or 2.5 inch pipe all the way back...maybe duals out the sides, or straight out he back

mine sounds wayyyy better than that video too!!

 

did you only do one of the silencer box things?

 

have you made up your mind yet ?
