Pacemaker headers

[brods2151]

Got a 2.5 inch catback, looking to fit these this week.
Will it change the note at all, quite like the sound im getting out of the sv6 as is.

[Kal123]

Yes, pacemaker's will change the note quite a bit. It will give it a much deeper/nicer note..

[Fishman88]

I got these pacemakers (with the performance coating) on my car wit twin hi flow ballistic cats. Well worth it!

[Nitronic_12]

Yes, Pacemaker headers have been known to change the note on any setup, including stock.

Though with yours it might just cause a deeper snap crackle pop. But it's your setup mate.

I'm looking at doing my exhaust and I gotta say that while choosing headers seems pretty clear cut, getting the right exhaust setup that's not too loud and doesn't sound like a fart seems like the trick.

[brods2151]

My exhaust doesnt crackle at all, i was really surprised when i got it back.
My mate has a vz ute and it sounds so much different.
So pacies will give it an even deeper note? sweet =)
Whats this performance coating stuff? how much is it?

[Exidor]

I have heard you should not use mild steel for the headers
because this can contaminate the cats.
Is this true?
Heard the same for exhausts also.

[Nitronic_12]

Certain metals at high temperatures can release amounts of different gases. This could contribute to it? I'm not sure, but just maybe.

[Fishman88]

This High performance coating i finks its ceramic reduces engiine bay temps, increases the life of the headers and look rellli sexc under the hood!! ill take fotos soon! n post it in my ride i fink itz well worth it! i fink itz like 150 - 200 or so extra? mine was done for 980 fitted!

[Fishman88]

Yeah I got quoted $1040 today.

I'm still yet to decide on the cat back: do I go for single 2.5 or twin 2.25?

The single will give me better torque, the twin will give me better power what to do, what to do, what to do!!!

[brods2151]

I got the 2.5" and dont regret it, bring on the torque i say.
Make sure you get 2 mufflers otherwise it will sound like poop =)
My extactors go in thursday, ill post a sound clip when its all done.

[Kal123]

On the 190, will high flow cats make much of a difference? ie Sound/Performance

[Nitronic_12]

Send Fishman a PM and he'll tell ya.

[Fishman88]

Yes it does well depends which hi flow cats u get! i got the ballistic hi flow racing cats ive been hearing only good things about these cats on the ls1 forum. Chek out the sureflo exhaust website for more info. For the sound i cant explain it relli but sounds better then stock but ye only way to know is by listenin it in real life too bad ur not in nsw... I am very happy wit wat i got.

[BeKzZz]

Wat is the best size headers for my VZ ive got a 2.5inch cat back redback exhaust?????

[VzSS06]

Afew years back i had pacemaker extractors fitted to a 6cylinder i had while retaining the stock exhaust and it made NO difference in noise.
Also if you are going to get them ceramic coated save some pennies for o2 sensors,i had ceramic coated pacies fitted to my 6 litre and the coatings damaged my o2 sensors,upon doing a search afterwards i found this to be a common problem.

[brods2151]

Cheers for the heads up man.

[brods2151]

Extractors went on today, extremely happy with the result.
Louder and deeper exactly what i was looking for, with the air con on it has a rumble like a mini 8 =)
Ill try get a sound clip up tomorrow afternoon.

[Kal123]

Brods, do you think they were worth $$?

I got a quote for CC Pacies installed for $1000 today..

And any chance of a sound clip?

[brods2151]

Ill try get a sound clip today for you, havnt been on the forum for a bit, sorry.

Mild steel is cheaper and rusts easier. A mild steel exhaust will last you FAR less amount of time than a stainless steel system.

Well i recorded a video on my phone but how do i upload it?
