Ok, I have a 89 vert that I am trying to get some good flames out of. Right now 1 out of 10 big pop/booms from the exhaust gives me flames. I have a stock header going to a Racing Beat downpipe replacing the two pre-cats, then to replace the main cat I went to the exhaust shop and had them make a peice of pipe with flanges and fittings as the intermediate pipe, then it goes to the Apex'i N1 duel catback setup. I have the air pump line still going into the exhaust through the custom intermediate pipe. Is the air being pumped into the exhaust hurting my flames or helping? I am still running 89 oct. gas, Should it be higher? Emissions are not a concern. I do plan on getting a RB header in the near future, but what can I do now for bigger natural flames? Any help is appreciated.

 

sorry double post
