Wildcat or Hitech headers

[Mopar69/95]

i have the hi techs and have had no issues for at least 5 years, picked them up from the factory here in SA and good blokes there. had a typical cracked stock set that i replaced and was so quiet with stock exhaust but then changed to 2.5 with high flow cat of ebay and turbo muffler. doesnt drone but gives a nice bark when needed.

Good feedback mopar and ruffy. I will be going for one of these two.. at the moment its the Wildcats, as i dont need stainless because i am going to get mine ceramic coated, and the Wildcats are $250 less. I also like the idea of getting rid of the restrictive bend coming from the headers, which the Wildcats and Hitechs do.
I like the twin pipes coming off the Wildcats,which is what the original Hitechs had.
What bolt couln't you get in ruffy? middle bottom somewhere. I was thinking of notching those out so you could put bolts in first and just slide the extractors on.
Cheers,

Hey, I would like to know the reason why that on the stock exhaust just after the flange that the headers attach to, the pipe is pinched/sqashed together restricting the flow. I know back pressure is needed. But is it needed? Even after you've installed extractors?

I'm not fixing it, I'm improving it!

Has been discussed many times on here. It's there from the factory for front driveshaft clearence.

I've recently done my injectors, FPR, fuel filter, leads, plugs and rotor button all in an effort to hopefully improve fuel economy and performance. I'm not sure it has but at least I know everything is new...

I have no evidence to prove this, because I have put a roof rack on before the extractors. My gut tells me yes. My other car with the wildcat's and bigger tyres got factory fuel consumption on the highway from 12.6 litres/100km, down to 9.9 litres/100km.
But as always, it depends how heavy your right foot is!

Yeah, middle bottom somewhere
If I had to refit again, I would put a stud there and start the nut before fitting the intake manifold. The intake will slot over it, I was using a 2000 model intake, may have made it harder.

OK, decided to go with the Genie Wildcat headers for a few reasons. They seem to have some good reviews, are made in Australia, the secondary pipe that replaces the restrictive OEM one is a twin pipe job that really de-restricts the system, and the price is good which saves me $250 over the Hitech model and can be used to pay for the ceramic coating. For me, the ceramic coating is a priority to help reduce under hood temps.
