right im gettin a rage 3.5 or 4 inch stainless steel backbox but am unsure which size box length 2 get as their avaliable in both 400mm and 250mm lengths.iv read that the inlet pipe is 2 short 4 a fezzy so if u got the longer box would this mean the inlet pipe wud b ok?if it makes no difference what size box shuld i get and will most garages do a custom job on the inlet pipe.oh n what dya reckon wud look beta on a si rear a 4" or 3.5" tip?

I have a rage 4.5" rolled out back box on my FRST and am very happy with it!
After a lot of confusion, I realised that some places sell these as 5" tip and some as 4.5" but they are exactly the same box.
Originally I had a magnex system which was good but too quiet so now I get a good burble on tick over and a roar on take off! and I can always put the original magnex box back on cus I got a local garage to insert a small piece of stainless cus the magnex was slip fit and the rage was a straight cut. The garage done powerflow exhausts which meant they had all different stainless pieces and the machine to bend it into shape.

I went with the shorter box cus the longer one was pushing it for space and the magnex came down at the wrong angle for the rage to go straight on. Also I figured that the smaller the box, the less it will silence!!!!!!!

Measure how much space you got, but I would go with the shorter box anyway, cus it's easier for the garage to fit it with the extra space.

And go with the 4" cus big is always best!
