93CutlassSupreme Posted December 10, 2003 Report Share Posted December 10, 2003 do flowmaster 40's just bolt right up to a stock single exhaust on a 93 Cutlass Supreme 3.1, or is modification of the exhaust pipe or muffler braket necessary?

WhiteOut Posted December 10, 2003 Report Share Posted December 10, 2003 When you say 40's I would assume that you mean more than one, as in your going to add a dual exhuast setup. If thats not the case it should be a simple matter of cutting off the old muffler's and fitting the correct pipe diameter 40's (2" I think) onto the car and securing it with a clamp. If not, then you'll need a y pipe and another couple sections of pipe to make the dual configuration work, and since thats a lot of new joints welding skills may come in handy.

93CutlassSupreme Posted December 10, 2003 Author Report Share Posted December 10, 2003 no, just planning on one muffler i guess it looks like something i can do myself Quote Link to comment Share on other sites More sharing options...
topless94style Posted December 10, 2003 Report Share Posted December 10, 2003 Chances are, you will have to modify or make a bracket to hold the muffler up. Make sure you get the right size muffler and it should slide on, either weld or clamp. Get it hung and youll be blowing in no time. Quote Link to comment Share on other sites More sharing options...

If so, those are the worst things ever made, they last one winter before rusting through. I have went through a few on my old car, same with a friend of mine on his GA.

TeeJay3800 Posted December 10, 2003 Report Share Posted December 10, 2003 My Flowmaster 40 bolted right up to the stock exhaust hangers with very little, if any (I don't remember exactly) modifications. The only custom work that had to be done was a little special bending of the tail pipe so my tips would be where I wanted them. Quote Link to comment Share on other sites More sharing options...
cardude43 Posted December 11, 2003 Report Share Posted December 11, 2003 My 40's were welded. Only, because were I live were are not suppose to work on cars. So I just had the muffler shop do it and the welded them. Quote Link to comment Share on other sites More sharing options...

93CutlassSupreme Posted December 11, 2003 Author Report Share Posted December 11, 2003 when the car is up on jackstands when i'm changing the rear brakes saturday i will measure the muffler and see if flowmaster makes one the same size. Â my muffler is bolted on, not welded, therefore i am assuming it isn't a very hard swap correct me if i am wrong please Quote Link to comment Share on other sites More sharing options...
93CutlassSupreme Posted December 11, 2003 Author Report Share Posted December 11, 2003 what size is the stock exhaust pipe going to the muffler? 2 inch? can i measure this with the muffler on or do i have to pull the muffler to check?

TeeJay3800 Posted December 11, 2003 Report Share Posted December 11, 2003 I think with the 3.1 the stock diameter is either 2 or 2.25". My Flow has 2.25" in and out and it fits just fine. Quote Link to comment Share on other sites More sharing options...
sonyman87 Posted December 11, 2003 Report Share Posted December 11, 2003 All you have to de besides welding the muffler on is weld hanger wire to the muffler so it will hold in place with the current rubber hooks Quote Link to comment Share on other sites More sharing options...
93CutlassSupreme Posted December 11, 2003 Author Report Share Posted December 11, 2003 i know how to weld, but i don't have any welding equipment, so i will just use a clamp to secure the muffler to the exhaust pipe, like my current stock muffler is set up Quote Link to comment Share on other sites More sharing options...
93CutlassSupreme Posted December 11, 2003 Author Report Share Posted December 11, 2003 do most auto parts stores stock muffler and exhaust clamps and straps and mounting hardware? never bothered to look Quote Link to comment Share on other sites More sharing options...
topless94style Posted December 12, 2003 Report Share Posted December 12, 2003 yes auto shops will sell clamps hangers and pipes. Some will stock more than others so you have to look and ask where you decide to go. No big deal though im sure any store will get you what you need.
