I HAVE A 1997 RAM 1500.

WHAT IS THE STOCK DIAMETER SIZE OF THE EXHAUST?

SIZES FROM FRONT TO BACK?

WHAT ARE THE SIZES THANKS.

 

I have a 98 QC. Mineis 2.5" and from the muffler back I think it is 2.75"

 

My 2001 exhaust is 3" throughoutEXCEPT where the Cat and Mufflerconnected. It decreased to 2.5". Ihad a guy cut the muffler and cat offpast the 2.5" collars and install a 3" in/out high flow muffler and cat.Now I have a relatively cheap (though ugly heat treated red and stock) 3" stainless exhaust system. Never worried much about looks under the vehicle. Guess I could get one of the longer stainless tips and nobody would be the wiser.

 

2.5" here.

 

I have gone and looked under the truck and it doesen't look like it is 3in at the cat. I am just really trying to find out if I am going to have to replace my cat.

Is there a 3in cat that directly fits my truck?

I am going to run a 3in exhaust with a electric cut-out after the cat. The regular exhaust will come out at the back but above the fender where you can't see it.

Going to have a 2chamber flowmaster muffler.

 

Please don't yell.



























j/k

 

???

 

Using all caps is considered yelling in cyber-space. I think Fox Fader is just messing with you. Although it is a little annoying.

 

I dumped my exhaust and it was 2.5

 

Oh I was just doing (???) for more answers[8D]

Yeah I got what he said.

So if I am correct I was told it is 2in piping going into the dam cat (which is small) and 2.5 the rest.
