On my pickup i had 3 in. pipes put on from the cats back as a true dual system. Got it done fairly cheap. Am pretty happy with it but am wondering if maybe i should kept the stock 2 1/2 in from cats back and then have my 5 in by 2 ft tips put on after that. Now what about a cross pipe connecting the two sides to balance out pressure. Want to have the best hp but yet mpg for the most part. I do realize i can't have both but can try. Don't really want to redo exhaust but am considering then might put on shorty headers if i redo. Any input appreciated.
Does anyone know which setup would produce the most efficient hp. I know you want backpressure but which one would create the scavenging effect better.
regardles what you do headers 2.5" 3." to keep the pressure and temp. the same you need a cross over pipe it will save you headaces in the end.ie. uneven head temps can leed to blown head gaskets or craked heads some times sound is'nt the best
good luck BRAD
