today i put my new rb collected headers along with the bonez high flo cat. i gotta give it to RB they make very good products. i also have the RB cat back and the entire system is awesome. anybody else have experience with the headers? it was a pain in the *** to get to the bolts actaully nearly impossible until i took off the acv. after that it was really easy.

 

nice!!!!!!!!!!

 

yeah man... very nice. i want to get these to complete my exhuast system along with some high flow cats. were did you go about purchasing the cat. looks really good and clean.

rx7.com thats where i got the cat and headers in one combo. they did a good job with all the hardware. even a block off plate for the acv. and an extension tube for the split air pipe.

 

if my memorie sevves me correctly you should see a 28% (40) hp to the wheel increase from stock ... good work ... i have a simalar system but full 3 inch ... loud as **** .. but its ingle exite and all custom but yeah good ****

 

40 HP my ***. I've got the full system, too. You see the most power when you take out the cats.

Mods in sig.

 

nice! wish i had money for one. now how about some sound clips!

 

the cats mak ethe system quoiet though dont they?

 

actually not really it still has a really nice tone. i didnt want an extremely loud system and this set up has a really deep sound to it. ill have a couple soud clips up soon and dyno results up soon too.

 

just for the record thoes hp number claims were not my own ,, they were from mazda trix i belive ..... im preaty sure thats where i read it .. just wanted everyone to know

 

Those numbers might be right for a turbo car, cause the free flowing exhaust will get the boost up a few psi. On an NA that's a bit too much, IMO...

And the cats would quiet it down, but so will those RB mufflers. Quality stuff.

Enjoy the new sound!!

yea I meant the cat would quiet the system down as oppose to the pre-silencer. Good stuff man I cant wait to hear the clips

 

only on turbos with the boost creap it causes. even then its hard to believe

 

i made a quick video so here it is. ill get some more later. like driving and whatnot.

28% refers to true duals, this is not true duals.

The turbo with boost creep is 59HP, not 40.

 

Because I feel like being a nit picker...
It is header, not headers.

Oh and, looks good man!

 

i dont see how since it has only 1 header coming off the motor.

 

Boost creep? It's just the exhaust flow being freed up allowing to turbo to breathe better. You need to look up what boost creep is. But then again freeing up the exhaust on a stock turbo model with an FCD and a fuel pump will net the biggest gains.

28% from true duals?

 

My butt dyno said +5 to 10 hp when I installed full RB exhaust (mine is not a full dual).

 

If there is one gearhead tool I swear by, it is the Butt Dyno. Sh^#-eatin'-grins tell the entire truth. 5-10 HP or 40 hp, the fun factor is still increased.

 

yes i love the new sound and my car just feels and sounds healthier. taking to the dyno right now! ill post results
