I have just had jamesvalvers old Back Box fitted up at powerflow, they done a good job of fitting it....



BUT.. there is nearly no sound differnce, is this because of the middle box?

He said it will make a massive differnce

he is going to remove my middle box and weld some stainless piping in there for 35 quid!

Will it really be worth it, will removin the middle box make a diffence in sound?



(sorry for the eassy)

NONONONONONONONONONO

dont remove the middle box, it sounds shit

just save up for a decent aftermarket centre section, dont just go cutting bits out, they are there for a reason, not just to make it quieter

anyway, for 35 quid, you'd be better off putting that towards a remus centre section, which would last longer than a hacked about one.

a backbox alone wont make a car any louder, people get their hopes up about it, but it never makes a difference.

Less back pressure is only advantageous on turbo cars. If your n/a car has no back pressure, it won't peform as well.

Chris, if you buy a remus one, it will last longer than a powerflow one, and you can get it fitted at work
