They are easier to install in a stock style exhaust system, which makes them attractive. |

#Equal primary tube length is very important for tuning and power output, but not to the point of obsesing over it. A regular Tri Y or 4-1 header will work wonders over the stock manifolds. | #Equal primary tube length is very important for tuning and power output, but not to the point of obsesing over it.
