Who makes quality test pipes for the Mazda RX-8? I know CanZoomer has one with a resonator; any others out there?

Rotary Performance (www (http://www.rx7.com/RPGReddyRX8exhaust/) ) has one

So does B&B Exhaust, you can get it from Vivid Racing (www (http://vividracing.securesites.net/catalog/product_info.php?cPath=17_18_1053_1139&products_id=2474&osCsid=69b0f2340d96cdf86d718d083666df0e) )

I have the RP midpipe. It sounds pretty decient, but there's slightly cheaper ways to go about it. On top of that their O2 fooler DOES NOT WORK. There's a few threads about midpipes and O2 foolers floating around here. Try a search to see what you can find.

*edit*
This thread has a bunch of good info.

The bb midpipe is excellent quality, if you don't mind the noise. The pipe is not yet offered with a resonator, but it is in the works.

I ordered a b&b mid pipe cus all the others were way over priced
after ordering I spoke to Huff who said the pipe was way to loud 99db
called back and asked if a resonator could be added and they said they would call back...Dennis called back and said yes for 25 extra and we are now going make all the pipes with one,just to loud without and you would be black flagged at any events.
so here I wait but at 275.00 beats any other prices I've seen.
canzoomer was 436.00 !!! sorry a little to sky high for a pipe that would cost maybe 150 for any other car. :D
