Dude, do yourself a favour and buy the ETM kit. Custom made to whatever you want. He will make your dump pipe, therefore no stuffing around with trailers or tilt trays to get exhaust done $$$$$??????? Quality +++ And on the quality side, stainless has a very large thermal expansion rate, in comparison to mild steel. The steam pipe has a stress rating of approximately 250 Mpa, which is ideal. Any softer, and they would melt around themselves, and harder and they would start to crack around the welds ( like stainless ). These things work very well, just take a look at how many happy customers there are out there. So like I said, don't look at the money, just buy it then it is all forgoten the first time you put the pedal down................or buy a sh*t one, then in 6 months you can buy one of ETM's. Cheers.
