Fujitsubo rm01a

[fire_king]

What do people think of running the above system on a boosted b18 making 320 bhp. System is suppose to be 2.5" but am told it's not a true 2.5" searching online it's more 2.3". I won't be running no more then 320 bhp. All input appreciated

Thanks

If your making that sort of power then a true 2.5" system at least would be needed.

Yes the RMO1A is 2.5" outer diameter, nice sound from them all the same, fitted one recently myself.

3" system is what you need
