Why don't you ask the people at the exhaust shop? I reckon they'd have a pretty good idea...

[dijm8]

yeh i knw, will be ringing in the morning...just more wanting to knw what kinda mufflers people are using these days

I'm using a massive muffler from a truck. Seems to keep mine pretty quiet. No idea what brand it is though.

I might be shot down in flames over this, but my X-force exhaust is roughly stock sounding on idle and CRAZY LOUD when you up it - maybe have a look at their resonators? Middle muffler is straight through design, so is the back.

Straight pipe as in, no mufflers from the cats back? no hotdog resonators, no cannons, just 2.5" pipe and nothing more?

Put 2 good sports mufflers in the middle and call it a day (one either side just after the cats, so one per bank of 4 cylinders), 'tis what i have on my stato (albeit ls1). And get told my car is quite loud? it's pretty good at cruising speed but if you open it up you know about it (and so does the neighbourhood)

ive just got 2 mufflers in the middle, but nothing after that

Have you got an X pipe? That quietens them down a fair bit too.

I got a muffler for my car that was to suit a rotary, so it has made a big difference to the noise levels. But was not cheap.

Thats what i have then, if its too loud for you then get a rear muffler, hotdog or resonator put in.

A member here, Sphinx, got EPAed and had to quieten his exhaust down. He Frankensteined up an exhaust with, I believe he said it was a motorbike muffler. Not sure how it would go performance wise, however it did reduce the sound a bit.
