hello, im planning on putting a new exhaust sytem on my ed xr6, i didnt want to spend over $500, and i wanted a power gain around 10-15 kw which is acheivable, though apparently to get any power increase out of the car the headers and cat must also be changed i was quoted $1370 for a x-force s/s polished header, 2 1/2 inch hiflow converter, 2 1/2 inch redback sytem. this seems excessive and i cannot afford that is it tru about the header and cat setup in this model, am i getting the bum steer, and does anyone have any pointers for me on what i should be looking for for that kind of increase? thanks sorry its long

standard cat is fine, headers should be replaced but don't need to be done immediately, the Falcons benefit quite well from just a cat-back system.
Just make sure you get mandreal bent.

Standard Falcon cats are actually very good, so i think he was just trying to see how much he could squeeze outta you.

a set of try y's, makes sure your cats have 2 1/2" inch openings, then a good 2 1/2" with a straight through muffler will help you get the gains you want.

as far as the cat issue goes, all the cats that are made in aust, all share the same catalyst brick, so you wont gain much from gettting highflow cats, by enlarging the openings you practically saved yourself heaps of $$$$$

hope this is of some help

the only thing is that your cat might be buggered, and that is why he is saying you need a new one, give it a tap and if it rattles its buggered. But unless it is not revving out or something it is probably ok

Cats are only designed to last around 3-4 years, you car will be about 10 or 11, so id get it checked and changed if needed.

I saw on JMM they had standard 2 1/4" to 2 1/2" cat conversion kits. I'm assuming this is just the ends, so it will connect up straight to a 2 1/2" cat back. Is this right? Also I've got a bolt on cat back lukey super system, and the front mandrel bent pipe goes down to 2 1/4" to fit the standard cat. If I was to put on a set of headers, would I gain much by opening both cat ends up to 2 1/2" and replace the front mandrel bent piping, or would it be only a pointless 1kw gain for an extra 150 odd dollars?
