Default Custom exhaust - a few questions...

Hi,
I have a 97 SE with 69,000 miles on it, today I bought a Flowmaster 80 series with 2.5" inlet and outlets (dual exhaust muffler, inside diameter), a 2.25 to 2.5 reducer, and a 7 foot length of 2.5" outside diameter pipe. I still intend to buy a few feet of inside diameter pipe so I can adjust the distance the bends are from the muffler.

My questions are:
Will my setup work by the looks of the diagram below?
Will clamps hold this all together? The 2.5 OD end ot the reducer fits in the muffler, but it is a tiny bit loose.



Thanks for any help!

Well, it'* not really a reducer, it'* more an expander. And becuase stock SE piping is 2.25" and the inlet on the muffler is 2.5"

http://www.flowmastermufflers.com/80_series.html is what I have, and yes it is a crossflow. So will the setup work, and can I use clamps to hold it all together?

How much would it cost to get 2 90* bends?

As far as I know, the Flowmaster 80 is used by a lot of guys and should work great. I haven't done one yet but I'm saving my pennies! As for the reducer, the pipe on my 95 SE is 2" so I'm gonna need to use one.

Will exhaust clamps work to hold the setup together, or should I get it welded? And how much would welding cost?

Check out BonneMeMN'* page.....

If you download the My 1993 SLE with Flowmaster 80 series video you can see he'* using muffler clamps. You can get the clamps with the hanger attached. I'm gonna use that.

It should be welded. Mine was $145 for the welds and parts (excluding muffler). Since you would only be talking labor...probably some where between $50-80 USD. Labor is typically $60 an hour. Call around.
