Cats and Exhaust Noise - Ford Forums

Yeah i'm thinking to get abit more power from my car by fitting a high flow cat. Will it give abit more power than standard cat???? Can anyone comment.

Myinterpretation of exhausts is that it makes more of a difference at the engine end then the back, ie if you change the back muffler it would do bugger all apart from noise.

This leads me to another thing about crappy exhaust noise. I hate cars that have these loud and a bad exhaust note.
Thats why i'm abit wiery of changing my exhaust. i want performance but i quite like the stock sound, cause while a good exhaust note is always better trying to get a good note is friggin hard.
We got a turbo exhaust fitted to our EB wagon the middle section of the exhaust and it sounded pretty crap.

Matey!!!! The extractors, engine pipe and cat would be the first place I'd hit. To be entirely honest, the Ford exhausts on the EF aren't that bad for flow etc. The extractors will make a HUGE diff - trust me! Buy stainless components to the rear of the cat as a minimum so the cat doesn't get blocked up by corrosion particles.

I wouldnt bother about a high flow cat, youd be lucky to get 5hp out of one.

Just go with extractors, 2.5inch pipe, flow through muffler and a resonator, with all that it will sound like a beast :D

Yeah as i said i don't want it to be loud, or sound like those ricers who try to imitiate V8's.

What implications do modifications like this have on your insurance?

Chris,

I shouldn't effect insurance in the sense that i'm getting only a high flow cat. So it's pretty legal. Having a high flow cat will only increase power but won't change the sound of the car. I have already changed my exhaust from the cat back (only a replacement stock system with a tip).

I am after something that will give my car abit of power and a few kw here and there is what i'm after, as i cannot spend too big on go fast mods yet.
I still have to get a set of shocks for the rear, considering a tower brace and perhaps nolethene bush's.
:eek: :eek: :eek:

I'm still looking into getting a cold air induction setup as well. So all in all i'm targeting about 118kw - 120kw at the wheels.

:D :D

EF
I think I owe you some prices and quotes, for the setup too, dont I. Correct me if I'm wrong.

I would definitely go for the cat only because the original would be stuffed after the kays your car has done (if there is anything left inside it :wink2: )

Doc,
Yeah i think i did ask you a while back. I went to ford muscle parts they quoted me $250.00 for the setup of coldair induction and that included a K&N filter. I'd like to know the price for the cold air induction setup only without filter as i already have one.

Ring back and ask Bob, I think from memory the filter is about $50.00
