Hi everyone, i got a full RB set up( header, big cat and a muffler) i want some noise and more flow because this big *** cat is very restrictive, so should i take the cat out and beat the honey comb out of it and put it back on, or put a straight pipe or prescilencer. i wanna make some noise but not like a 454 big block noise. what should i go with?

 

Hello,

If you have a full RB exhaust why are you woried about hollowing out your cat? The full RB exhaust replaces the cat.

What exactly is this "big cat" you're refering to?

The full RB setup includes: #1 the header #2 the presilencer (I have a feeling this is what you're calling the big cat. It's not a cat, it's a presilencer. and you want to keep it. just the way it is. don't beat the **** out of it) #3 the intermidiate pipe and muffler.

If you have all three of those things. Install them in that order and your car will sound great. Not too loud, not too quiet.

I hope I understood you correctly. If I didn't and you don't have a presilencer, buy one.

Good luck,

--Alex

 

yeah it is a big cat, its like 20 in long and 4 in width, but i was wonderin if i should take the crap out of it, but i like the prescilencer, where can i find a cheap (on price) and easy to get RB prescilencer?

 

That 20" longx4" thing IS the RB presilencer....if you want the car louder...take it out. Go to a muffler shop and they can easily fab up a pipe..probably for under $30...if you get it flanged, you can replace the straight pipe when you get sick of the noise.

BTW..if it is a 12a model presilencer, it probably does not have the inside diameter a 13B version has...that may also be another option.

 

also u can sell the presilencer

 

The RB presilencer in not restrictive.

Your car will sound better with it, than without it. I promise. I've heared many (with and without)

 

I almost tried to buy it from him.....LOL

 

personlly iv heard a 13b brigy with the full rb exhaust i had to put my head near the exhaust to hear it

i was really dissapointed but its great if you want a quite car

 

i know what a prescilencer and i know what a cat is and the 20 by 4 maches perfect for my cat, this is my cat http://thumbs.1aauto.com/CCD/1ACCD00074.jpg, i bought the car with the rb set up it has now, so maybe the guy before had the pre s and tok it off? ,

 

Maybe he just Replaced the Presilencer with a Catalytic in order to get the Car Emission Tested?..(guessin.)

 

Cars that are louder than they are fast = Rice.


IMPO.

 

Sell the RB system, then buy an SDJ header, Borla Xr-1 as your presilencer, and then use any rice cannon you want as your muffler

 

yeah maybe he just put the cat in for the pre, but anyways im going to get a presilencer, thanks for all the help guys

 

Hmmm i like that idea. What i was thinking about doing was using the RB header and now using (what you just said) that borla XR-1 as the presilencer then go straight to my magnaflow muffler that i have now. I bet that would sound nice!

 

yes

 

+1 FTW

this is first startup from 6 months of storage, smoke is from the fogging oil.

 

that sounds pretty good, i would like to hear it at high rpm, obviously after 6 months ur not gonna redline it.how does it look? is it like the rb? or is it big and round. I couldnt see it becuase of the smoke.

 

sounds pretty good. stock port?
