Gale Banks 48123 exhaust system.

Recommended Posts

I finally pulled the trigger on getting the Banks system. The 48123 was designed for the Titan, but will be close enough that I can make it work. I will do an in depth on the install with any mods required. Looking to see where my mpg's land...well, that and a serious belch when I stand it.

Hey @SmokedChops, did you end up installing it? How did it go? How much modification was needed? How about performance gains?

Sorry for the delay...just now wandered back on here.  The front flanges on the  y-pipe/crossover that bolt to the catalytic convertors need to be cut off and clocked to line up with the bolt holes on the NV convertors and re-welded.  The crossover pipe needed to be shortened to match the NV spacing side to side.  I opted to not use the Banks muffler as it was basically a telescope (could see in one end and out the other), went with a welded stainless chambered turbo muffler  (Flowmaster knock-off).   If you have a welder and a sawzall, it is all easily do-able.  Might need a piece of 1/2" steel rod to make your own j-bracket to line up with the NV hanger spots.  Gained about 2 mpg on the highway - average 14-15 on the highway.  Low-end grunt is more pronounced when pulling a small travel trailer.  Was it overwhelming "oh my god, I have 500 hp now and get 24 mpg!!" No. Did it add what I thought an oversized single exhaust with a fat turbo muffler would do for the $450 and several hours invested? Easily.

Hope this helps.
