Haha, yeah things went a little bit off topic!
Agreed, scrap it.
I use to have a suzuki sierra 1.3L with extractors and a 2 3/4 straight through no cat pipe. Wasnt that loud, had a bit of a roar, but not loud. It had pretty much zero back pressure. When taking off from stopped the engine would stall really easily unless the engine was revved enough to create enough exhaust gasses to pressurize. You couldnt just stick the boot into it, you had to give it time to get sorted, however once the revs climbed the pipe allowed the old girl to rev like crazy.
The muffler reduces sound from the engine, if you have a straight through it obviously restricts the gases for a shorter time and usually is louder. My v8 was so restricted with 2 mufflers, one was removed by previous owner to get it to run a bit freer.
In my opinion removing the muffler wouldn't make much difference to overall performance or volume if the exhaust stayed the same length. I think in the case of the 3L its more the diameter and length of the pipe that makes the difference. I bet if you removed the cats it would splutter with no back pressure.
Got a 4.2 petty, noticed recently that the exhaust fumes now have what is best described as a sickly sweet smell, could this be because the cat has now failed?...... No smoke of any colour, just the sickly sweet smell.
Don't stroke it, TAP it!!!!.....
