cat-converter

[turtle240]

i was trying to put my cat-back on today and i looked at my cat and my flange is paper thin so instead of buying a new cat for $150+ i want a test pipe for like $40-$80 and i was wondering if it will throw codes and whatnot

so just let me know

pretty sure the 240 doesn't run a downstream o2 sensor..at least the s13 doesn't...you shouldn't throw a code, but your 240 will kinda sound gross...gl man.

You won't throw any codes. Not sure it will change the sound of the exhaust, thats usually handled by the resonator and muffler after the cat.
