$50 pm me if interested, boss only.

If you know a panelbeater, get them to chuck it on a chassis alignment machine and they'll be able to tell if it's not right very quickly. May have had a whack and put one of the towers out slightly?

Ok, well I've been doing the old google thing, and it seems that the general concensus is that the important bit is the distance from the collector to the first chamber, whether it is a straight thru resonator or a muffler? Seems to be between 8 and 24 inches depending on the motor, and that what you do after that does nothing as long as you don't restrict the gas again, and the outlet from the first chamber is larger than the inlet, as the gases think they have been set free if you do this. You can put a muffler on the end, so long as it flows at around the same rate as the engine, which is hp x 2.2, so if I have a 95 hp motor, if I'm lucky, I should make sure that the muffler flows at around 200 cfm? This is at variance with what I've been told by some people who should know, in that I was told that any old muffler will do. Interesting article here on this. http://www.superchevy.com/technical/engine...st/0505phr_exh/

Thanks for that, so what about 4 into 2 in a 318, will this give more peak power?

You should be able to pick up an aftermarket Luk or the like for under $300. Shop around.

Is it a flaw, or does it equalise the cylinder back pressure? Maybe it's a mistake to just try to remove the gasses as quickly as possible. I guess if you put uneqal back pressure on the pistons you would upset the engines balance? Does this make sense?

Ok, going down to my little 318, it also has twin pipes down to a collector under the car. Again, why? Would it make sense for me to run twin pipes all the way to the back, or not, and if not, why? Everyone has told me that the collector is the hardest part of the system to get right, so again, why have it? If it's a weight thing, I can live with it if I get increased performance. Any reasoning would be great, why mix all the exhaust gasses together with the resulting constriction that must occur? Thanks.

Hi, I've got a 4.1 medium case if you're interested?

Hi, 260x150 is right by all 6 of mine, 318's. Yours must have been changed?

With the dollar where it's at, I just ordered 2 sets, cost $65 per pair landed. Got to be good at that price.

Who's doing what where? Has anyone chased Rog up at the Karaka Tree Motel for a group discount, and is anyone else interested in doing this? It's only 4 weeks away!
