Anyone do this yet ? Just their front pipe. I did that on my 10th and was like that till Greddy exhaust and on the older model it opened it up and soundded better. Wondering if anyone here just did the larger 3” front pipe and evaluated. Thx
The factory exhaust is 50mm which is basically 2 inch. It also squishes to an oval in the mid aera so is technically a little less.
Doing only the front pipe will do absolutely nothing because the downpipe and axle back will still have the same restriction. You'd want to do the downpipe first most definitely.
GReddy never made a downpipe for any civicX and made the front pipe only for FK8. For all other models it is midpipe back.
