I6 Sports Exhaust

With my tax money im going to get a set of pacemaker headers and 2.5'' redback sports exhaust.

i am also considering a high flow cat ($200 extra) because i see the existing one a big restriction not only because its not high flow but because the input and output diameters are alot smaller than 2.5'' therefore creating a restriction.

do you think it is worth the extra money for a high flow cat?

Re: I6 Sports Exhaust

I really dont think its worth the extra money on top for a high flo cat... just get a standard 2.5" one... even without a cat there is no difference (Ive been told 1rwkw) so new ones dont really restrict anything... its only when they get old and worn out, but if u were going big power i would reccomend one, in this case not worth the extra cabbage.

Re: I6 Sports Exhaust

You don't need a high flow cat.
When you have your exhaust system fitted, ask the installer to cut the ends off your cat, and open it up to match the 2.5" system.

Re: I6 Sports Exhaust

Would that be considered tampering with the cat, Soxx? I'm sure the EPA will go for any chance to slap you with that $20,000 fine..

So long as the core is not changed it is legal. It is fine to cut off the end pipes to open them up.

i know of one in QLd .. a dual fuel AU with a 'hollow' cat... $1500 fine... and a defective vechicle sticker

I always thought the fines were larger but his was only $1500..

For the sake of the environment and the next generation ffs dont remove or hollow the cat please

No, as if the EPA used a 'sniffer' to check emissions, it will still be fine, because the insides are untouched.
I should make this very clear, that the cat still works as intended, all you are doing is increasing it's flow capacity by opening up the ends.

I agree... i was offered not to have a cat put in my new exhaust but i opted to pay more for a new cat... its just not worth it, and besides some of the deadly shit that comes out the exhaust... its a problem and weve all got to do our bit.

Re: I6 Sports Exhaust

I paid under $100 including postage for a 3" stainless steel high flow cat. I think someone's trying to rip you off!
