I ordered a flexpipe section from ATP Turbo and noticed that the inside had pretty decent ridges for the flex section. The flex pipe I just had on the car had the same braided material on the inside and outside. Im not sure if this would cause any issues with exhaust flow? Just curious, only because I think i heard someone once say they had an issue with their flexpipe being a bad design. Who knows!

This is the ATP one. Notice the ridges for flexability





For the regular flex that I like, the inside is the same SS braided mesh material. Like this...

 

Pics of the flex would be great. Im having a hard time tryin to picture what your talking about

 

Cool, I just posted up pics.

 

the braided flex sections have a bad habbit of imploding on the inside and causing a major restriction

 

the one you have now is the good one that doesn't fail.

 

Both don't look great, the 1s we use are virtually perfect inside, with only very small "lips"

 

Would you happen to have pictures and/or a source of the flex pipes?
