now don't go and put the really really really cheap stuff and then it'd do something weird lol. regular has worked for me and i've even put some really cheap stuff and it did make a bit of difference in the idling but nothing major. 
as soon as i put a better (regular still) type of gasoline it ran fine again.

BEEF!!!!
I still love my rotaflo, but for post '76 cars in Cali, stock looking will get the least hassles.
BTW...how are the the rotoflo resis at mellowing P-Ports. Yours pulling into the carpark wasn't too bad. Most likely will try to run 3 in a row.

That '79 sounded perfect! May have to go that route
So, those are Rotaflo resi's...and what size rotaflo? RF300 or rpf250?
and where are you collecting the pipes, just before the diff? and how long does your collector run? To the end of the box?

Muffler is a RPF250, the resinators are not Rotaflo (I don't think they made resi's back when I had my system made) pipes are twin to just before diff then short collector and 3" over the diff into muffler

Here's some pix of my Rotaflo, plus in interior shot. WELL WORTH THE $$
...plus, there are some Aussie cars making over 600rwhp running one of the RF300's!...and within track sound limits!
These are basically the best until you start making your own...(and yes Rice Racing...I know you prefer the SMB's =)
It was just over $300US shipped. Unfortunatley Jon, the original owner sold the company, but as far as I know, the quality is the same.
