I'm looking to quiet my car up some without too much hassle. I have an Apexi N1 single catback. I also have a hi-flo cat but the car still is somewhat loud. I like the look of the RB exhaust and I've heard it has a mellow tone. The N1 silencer is a quick fix but you lose top-end hp with it. Anyone know how much hp you lose with the silencer and does it really quiet the car up?

 

The silencer makes things pretty quiet, but think of breathing through a straw...

 

youll lose power with the silencers...i will only have them in if I know I wont be at play. its definitely a difference...once they are out its like being with yer girl without a jimmy...it sucks wearing the hat.

have you heard the rb? you might like the pettit as well.

I kinda figured it would cut out power - you never know when you're going to come across that Z06 or Supra - not a good time to a have restriction in the exhaust - might have to check into that RB = never heard the Pettit though

 

the pettit is not as tinny sounding as the rb...at least to me...it has a deeper tone overall.

 

I don't know if there are silencers available for the RB (at least the Duals). I've had the N1 Dual (w/silencers), and currently have the RB Dual on there now.

The N1 Dual has bolt holes to secure it's silencers, the RB does not have anything I can see of. If there are silencers, it uses some other method of securing them on.

I can say that with a DP and hi-flow cat, the N1 Dual w/silencers is ok noise level wise, but was way too loud (even with silencers) when I went single turbo. Never really drove it hard w/o silencers, so can't comment on hp loss, but I'm guessing it's a bit.

 

I have the RB...Don't think it sounds tinny at all...But then again I have never compared both the RB and Pettit duals...the RB is really just a bit louder than stock with a deep note and then really screams at wot.

 

I'll have to say the same as well. Nothing tinny about the RB from what I can hear (and believe me, when you go single, you hear your exhaust). If anything, it was the N1 Dual that had a bit of 'tinniness' - or maybe more of 'shriek' is a better description...

 

Artguy, are you comments based on the "new" (actually their really old design) RB cat-back? For a while there, they were rebadged RSR pipes. But last year (?), they went back to their original design. I have the "new" design and I don't find it to sound tinny either, but I still have the stock main cat.

 

I've got the N1 /w silencer, dp, and usual exhaust stuff. It sounds like crap with the silencer in but you will have more low-mid torque than w/o it. W/O silencer your top end will really be noticably better and it sounds awesome. It really sounds like a monster uncorked.

I don't have a boost controller or a large enough wastegaste to have an open exhaust, (stock non-seq. turbos /w Petit ECU) so I run the silencer It's about 3-6 dB quieter than w/o the silencer... that's a HUGE difference! During street driving it almost half as loud, but it also sounds like the car's really congested and needs some tums!

 

I have the M2 dual tip. I find it be well constructed and quiet enough (my wife has never complained) and most people who have heard it run thru the gears comment how nice it sounds. Tom

 

i like my RB dual tip. its the black one

 

anyone want to trade an n1 dual for a pettit?

 

not if they have half a brain..........oops said that out loud lol
