i have a 79 scottsdale with a 350. i am running the exhaust right in front of the back tire comming out on the driver side. i am running straight pipe 2.5 in, so i added a custom made tip made out of two one inch pipe side by side and now it shoots out flames. is this because the back pressure is too high at the end or is this another problem, and if it is because of too much backpressure, is this a bad thing.

too much backpressure will cause a tremendous amount of wear and tear on you engine. it is struggeling to burn the fuel it is pushing in and air it is trying to suck in at the same time as push it out. but on the other hand, most likely the flames are from the amount of fuel that is not being burnt after it is compressed and tired to be burnt. it may be buring while coming out of the headers and pipes. i would consult a true engine mechanic if not at least a smog tech. sorry i cant be of much assistance im still learning.

You may be a little rich but a 2.5" pipe is 4.91 sq." and 2 1" pipes are 1.57 sq" you have a serious restriction.

You're running too rich and too hot.
You're also subject to a ticket since it doesn't have factory exhaust.

No, it's because your running way way to rich. You need to lean it down a lot.
