I bought a 2.25 inch Flowmaster 40, acouple exhaust clamps and a nice tip, all the make for a pretty decent exhaust system. Howeve, when I picked up the flowmaster, it sure seemed like the inlet outlet where big, so I measured my stock piping and it measured 6.25 inch circumfrence, so if my math is correct, it's about 2.07 inches... 2 inch pipes. I don't think flowmaster makes a 40-series 2 inch muffler. This throws a serious kink in my plans, as this was my Thanksgiving break project. Any ideas on how to fix this mess? I've looked and I couldn't find any 2 inch to 2.25 adapters... I need to use clamps because I don't have a / don't have acsess to a welder.

Why does flowmaster list a 2.25" as working with a B3000?

EDIT: Yeah, just checked it again by unbolting my exhaust and doing a direct circufrence measurment... Mother****ing 2" inch exhaust. No wonder this truck seems to suffering from poor exhaust. I think I just need to find a 2.25ID to 2ID adapter..

 

Any advice?

 

Take it to an exhaust shop and they have reducers that they can weld on.. that's what I would do- good luck!

 

Personally i hate clamped exhausts...I think they dont look good....

You can take all of that to an exhaust shop and have them weld everything....

What are you doing for tail pipe hangers?

for sure dude.. just take it to a shop. if you have all the materials then it shouldn't be too expensive. cost me 50 bucks just to weld everything on

 

So what are the stock inlet and outlet sizes as I would like to just replace my muffler and keep the stock pipes.

 

Did you consider that the flowmaster will fit on the outside of your pipes? Did you try it?

I have a 40 series and it went right on mine -- but then again I welded mine up.

 

im pretty sure that there 2 inches... take it somewhere and theyll do it for you...

 

On my truck, the shop cutoff the old exhuast behind the cat, then look to have stretched a 2.5" pipe and fit it over the pipe coming from the cat, and welded together.
Anywho I agree with the other guys, go to a shop
