Tim,
Did you have any trouble welding onto the old muffler? I have heard from some guys that the lead on the inside can make it difficult to weld but had not tried. Joe A |

It was not too difficult Joe (easier than old contaminated aircraft exhaust stacks, harder than fresh .035" walled 4130 tubing). I also tig welded a few pinholes in other places on the muff and on a few of these, the thin outer wall would burn away easily exposing a larger hole to fill. One just needs to make sure to use standard practices of dealing with welding thin stuff. A newbie tig welder might have problems, but any tig welder that has experience with welding thin stuff will not have any problems.
I was shocked that my '79 SC still had it's original muffler (it was date marked 1978!). How many other brands of cars still have a relatively solid muffler usable muffler after 20-30 years of use!? |
That sounds like a great upgrade, but what about performance? Any difference?

I did some timed 2nd gear roll on before and after times on a similar weather condition day and got basically identical stop watch readings.
This is an old post, but I still am using this muffler (usually with the second outlet uncapped). I still will probably buy a M&K eventually, as this muffler mod sounds a bit too "V8 musclecar-ish" to me. I like it better than stock, but Ben's M&K has a more appropriate sports car sound to me. |
ya.... I am thinking cat bypass and M&K plus SW chip
thanks for the info |
Has anyone else tried this mod? I have a cat bypass and am thinking about trying it but I'm worried about it being too loud or sounding "no so good".

I have seen several similar threads about this mod. I may be interested in this. Does anyone have any recent experience/tips on this modification.
In particular, does anyone have a sound clip of their exhaust using this mod? |
