That's what I was afraid of. How are the systems that don't replace the resonators making any power??? I mean, the resonator pipes look like the most restrictive part of the OEM exhaust! If you don't replace the resonators I don't see how changing anything after them is beneficial. Hmmm . . . I gotta get my hands on the first generation JBA system . . . Thanks Slurp!Slurppie said:I might be wrong here but no other system replaces the resonators. Everything is from the resonators back or from the Y back. I researched all of the other systems before making my purchase and at the time, the JBA fit the bill in both price and OEM pipe replacement.
You know, I noticed it looked a bit weak there too.Caltitan said:The stock Y-pipe is pretty restrictive. There was a pic on a Titan forum months ago where a guy cut it open and it was basically two pieces of pipe smashed together to fit in a larger piece of pipe.
That is exactly what I thought. Can't beat real track testing. Thanks Head!the_head said:I gained 0.1 sec on average in the 1/4 mile with the Banks. I gained 0.15 secs on average when I replaced the resonators and associated piping with Moroso Spiral flow mufflers. I'd say the resonators are the larger restriction. The piping used is a double wall so it gets pretty small on the inside.
