87nt stock exhaust. flowmaster 40? if so is inlet size 2.5? any help or suggestions would be welcome.

 

Suggestion: Learn to google and search on your own...

Help: Here's the link to flowmastermufflers.com where you can find the correct part number for the size inlet/outlet you desire.

2nd Suggestion: If you must use a Flowmaster, use a 60. You don't have enough engine to make the 40 sound right.

 

very "cute" reply, no answer to the question of size, am sure your very good at avoiding that topic. thank you for your well thought out information.

 

I woulda said the same thing as johnZboy. A 5 second search would have given you plenty an answer... and he did give you some good info. YAY!

 

I must learn to be more gentle with the nOObs. They are so sensitive and easily offended.

The Flowmaster 40 is 4" X 9.75" X 13" - 19 " Overall Length. You have a choice of 2.25", 2.50", or 3.00" inlet/outlet sizes. As I have no idea what size pipe is under your Z I can't tell you which of these sizes will fit your application. You, or your muffler shop, will have to make that determination.

I still say a 60 series is the better choice, but do as you wish.

That's about all the specification details there are. The only other help I could offer would be to install the muffler for you, but, I've gotta' draw the line somewhere. That ain't happening!

Now, FYI, the only topics I tend to avoid are the ones I consider to be a total waste of my time. From this point forward, that will probably be all of yours.

You are welcome, and, have a wonderful life down there in the Palmetto State...

 

how about a tape measure? Have you learned how to use one of those yet? you could just go out and measure the exhaust on the car right now.
