Anybody know who carries exhaust systems for a 06 Cabrio Non S? I can't seem to find one.

 

I would just get an exhaust suitable for an '05-06 coupe. It will either work with the cabrio right out of the box, or the most you might have to do is lower the cross-brace under the car by about 3/4". There's a picture of my lowered brace here.

Basically, it just involves using longer bolts, and a few nuts on each side as spacers. The nuts need to be bigger-diameter than the bolts, so that they'll just slide over the bolts rather than having to be screwed on.

I've done this mod on a couple of cabrios (both Cooper and 'S') with no problems. In fact, I've put about 50k miles and a few dozen autocross events on mine.

 

I had the Megan setup on my '03 R50 and it sounded great. Here's the link for AutoXCooper. There's a sound clip on the page as well.

Will the Megan pass a Cali emissions test?

 

There are no catalytic converters removed(hence the term cat-back system) so yes it will pass.

 

Thanks, now I can save up my pennies. One more paycheck and it's mine!
