hi guys, i just got a racing beat cat back exhaust system, i really dont know much about it. it was a straight trade for the one i had. i heard that its about the best exhaust out on the market. any tips comments or advices would be greatly appreciated. i need to know more about it before i make another move. if its a good system then i would keep it and if not i got to start looking for something else. based on your experience tell me what you think

 

If your going to use for street then it's a good quiet system, but if you plan on racing here and there at the drag strip it might not do so hot for you. It's a 50/50 thing

 

in my opinion its ok if you dont mash on it on a ported motor but if your motor is oe works great .i just think they suck not enough flow for my taste

 

Not a racing exhaust IMO, but about the best you can get for a MILDLY modded street car that is VERY well built at a price of wieght.

 

Crappy exhaust performance wise compared to others out there. Not much better than stock.

But if you decide to sell, I'd be interested as good enough for my Auto Vert since it's a pig anyway. I'm currently running a TII stock cat back on it assuming it's a bit more free flowing than a NA cat back.

I'll be in San Diego the week of the 15th, so could connect then if interested.

 

hrmm... on the racingbeat website, they claim the turboii full racing exhaust adds 59 HP. im trying to decide between the apexi dual N1 or the full racing beat but i cant decide.

 

Depends what you want from your car. I'm pretty sure the duel N1s will outflow a 3" Racing Beat exhaust any day. But keep in mind it will be pretty damn loud if you go full exhaust. I went from an Apexi N1 to Racing Beat on my NA and don't regret it one bit. The build on the Racing Beat is top notch, and I didn't like the attention I got from ricers/cops/and possibly thieves with the N1.
And you're in the Bay area so may want to watch out for the noise. But the Duel N1s do look pretty sweet, I'm not a fan of the single exit because it looks like something is missing off the rear of the car with a bumper cutout with no muffler to fill it.

Keep in mind J-rat is running 10s with 490 rwhp 395 tq with a full Racing Beat exhaust. Here's an older video http://videos.streetfire.net/search/...8200e59cf0.htm

 

nah the sound level won't be that crazy but the flow will be way better for the car

 

i've got the cat-back with the downpipe and presilencer on my daily driver and i think its perfect.

 

exactly a mild up grade for the street. But if he/she wants to smash on the pedal at the track and get the max hp from his/her car up grade to a much larger free flowing exhaust to maximize his/her motor potential if the motor is no ported. If the motor is ported like mentioned above by manny you might want to upgrade.

 

Remember boys and girls, the question is about a cat back RB system, not engine back including the downpipe and presilencer. The latter will definitely give an improvement, but it's pretty much all due to the downpipe and presilencer.

Given the goal is for more go, totally run stock cat back and replace the cat with the downpipe and presilencer rather than stock cat and RB cat back. If the goal is simply bling and you need to replace your exhaust cans anyway, RB is as good as any choice.

 

ohh wow well as said i figured that since the price tag on these are so high then that would make them good. but i do like the N1's, how loud are those because cops are a little bit strick around SD , well at least with me they are.

ohh hozzmanrx7 i dont think i will be getting rid of the exhaust any time soon, i currently dont have any money to buy the n1's so that pretty much leaves me with no choice but to keep them for a while, hit me up in a couple of months to see whats up.

teddy so just curious but are you saying that if i was to port my engine the RB exhaust would be no good too me anymore?? what kind of street port can i do on my car to keep it smog legal???

thanks

 

Its hard to pin point the amount of exhuast he/she going to want to maximize to still stay within the means of being smog legal. he/she can still run the racing beat exhuast no matter what but like it was mentioned above if he/she wanted to get on the gas from time to time the exhuast wouldn't allow for the total amount performance being held back. I currently have a bridge ported motor with no exhaust sleeves ported, and when i tried to run the racingbeat/mazda trix exhaust muffler with three inch pipes my air flow was resticted when it got to the muffler. It would not allow the engine to run past 6 grand. I Had to run a full three inch exhuast with and use the HKS hyper sport muffler with a three inch inlet. My car is running a hella of alot harder, hella good, and tunning is much easier. Alot louder but well worth it for the performance and no restrictions.

Smog: racingbeat/mazda trix say that the slightest amount of porting or polishing can greatly effect the whole smog thing. It's a give or take game.

 

if you're not gonna keep the exhaust, i might be interested =)

 

i see, well thats cool im leaning more towards a turbo conversion than street port but then i hear that the exhaust for turbo models is different, i really dont see how a cat back system should be different for turbos and NA's

sorry for all those who think im trying to seel it, i just want to know more about it, not hoping to sell right now

 

The Racing Beat REV exhaust for the turbo is a larger exhaust system than the NA exhaust. http://www.racingbeat.com/resultset....rtNumber=16425

 

yea, thats the exhaust i was thinking of getting. either that or the dual apexi n1. on the racing beat website, it claims a 59 HP performance boost, where as the apexi website doesnt say anything about it. the apexi website also doesnt mention anything about it being a turbo or n/a exhaust. though i dont know if it makes a difference.

 

so if i was to buy a turbo FC does that mean my exhaust would not work for it.
(keep in mind that i only have from the y pipe back). i seriously dont know!

 

It will work, but near nil performance gain if a RB cat back for a TII.

If this is an RB NA cat back, it will have more back pressure than a stock TII cat back. So, if NA set up, will somewhat reduce your boost and thus negative effect on otherwise stock performance.
