Depends on how much power your engine is making. If you're engine is not powerful enough, it can result in loss of low-mid range torque even though top end power is better.
So what engine do you have?






If stock 6a12 n/a no need to waste on that setup. Customize a good stainless steel extractor, 2.0" - 2.5" piping (depends on transmission) a good quality center box and muffler. Got budget summore get e-manage piggyback. With right setup, an auto tranny also can habis meter on top speed.![]()

Okay thanks for the info bro
Is there any differences between auto and manual tranny exhaust setup?
how about 6a12tt with td04?
