That first one (two actually, looks like the same car) is broken man, mine sounds nothing like that. Mine sounds more like the third one warmed up, perhaps a bit lower than that even. I've got an AFe Takeda Intake and an ECUTek tune so that may be adding some other dimensions to the sound, but definitely not "raspy" like the first two videos. I see what you're saying now, but I really think something's wrong with his install.

I'll put up some video of mine tomorrow.

Oh, mine's also catted so there another variable to the equation. I guess we'll need to hear other non-catted non-resonated ones to see if thats what the problem is.

I just ordered the Nameless headerback today. :) I've done tons of research as well and that was/is on the top of my list so I finally bought it after months of reading about exhausts and hearing some in person. Can't wait to drive up to Washington to get it.

The non-resonated is definitely way too harsh-sounding from those videos. Very raspy.

I love the Perrin exhaust though and the resonated version is almost certainly going to be my exhaust.

As I watch the aftermarket continue to grow while my FR-S sits in the garage completely stock all winter I am continually pleased by the work Perrin does. The exhaust is excellent. Heard the non-resonated version in person a while back and it was solid. Not for me, again due to the rasp, but with a resonator I think I'll be very happy.

The fact that they are putting so much into the Vortech S/C has me really finding it hard not to consider them for a one-stop shop for power mods.

I have a Perrin non resonated and its not raspy at all...

I feel the same way. The time Perrin takes to do the write-ups on the FR-S/BRZ, help folks out when issues arise with their products, build their products in the US, are transparent in how they dyno their products and then back it up by showing the most gains in third-party tests, they've won my respect. I'll definitely be giving a close look at their SC kit when the time comes. If they keep it up, I might even rock their license plate frames :D

I've had the Perrin non-resonated CBE on my car for about 3k miles now. I LOVE IT! :party0030: Just about a 100 miles ago it developed a rather awesome burble close to something with UEL headers have. I have no idea how or where it came from, but I'm hoping it stays. :happyanim:

Recently I got a chance to hear a resonated version of the same CBE I have. Let me tell you I'm sooooo glad I decided on the non-resonated. IMHO, the resonated is way~ too quiet and tame for my taste. It's almost 95% of the stock system. Why throw down good money for something so close to stock sounds is what I say. The non-resonated CBE is quiet when you want/need it to be and loud/mean when you do. Perfect combo if you ask me.

I live in CA so I'm planning on keeping the stock front pipe w/ the stock cats. So the next thing on my radar is either a Perrin or Motiv overpipe.

I've had a couple of guys on Yamaha R1's chase me down about a mile or two down a stretch of road to ask me 1. what car it was 2. what awesome sounding exhaust I had on it. This coming from guys in R1's. :happy0180:

I keep hearing reviews like this and I've never heard the resonated version but, as I said above, I've heard the non-resonated version and it was just way too raspy for me.

But then I have to wonder.....was there a cat installed? If I keep a cat maybe I'll be pleased.

Ugggh if only vendors that sell aftermarket performance modifications could be like Zappos! I'd snag one and if I'm not pleased swap it to the other at no cost to me....

In my dreams. Shipping on these things is too costly for that kinda stuff.

Most of these reviews you see, you have to factor in if it's just the catback portion that has no resonator, or if they are using the OP/Frontpipe catted/non catted. When you add those two pieces, it gets REALLY loud, and develops that small rasp. It's just going to get worse with a header. :(

That video earlier even states its a catless header back system which is probably why it is so raspy. Read the titles guys.

I am getting the catted header back because if Perrin makes a catless header I would want atleast one cat in the car so I can still pass emissions. I also live in California too so its better to have atleast one in case a pig is a **** about things. Dont want to have it too loud especially once I have a header in their. So cal is rediculous when it comes to mods on a car. Otherwise I would get cat less and non resonated.

I really want a non resonated Header back but I am afraid that throwing a header on their might make it too loud and from the looks of it its already raspy as hell with the front/over pipe.

Yeah, we know that - the question at hand is do all catless headers with the non-resonated catbacks sound raspy? In other words - all these guys hearing raspy Perrin non-resonated catbacks in person, are they catless? If so we can all agree that that's where the rasp is coming from. That's really the point I'm trying to make here. The Perrin non-resonated catback on my catted system sounds perfectly fine, and there are guys saying that the Perrin non-resonated catbacks that they've heard are raspy as hell. That may be true, but perhaps it's the rest of the system before the catback that's introducing the rasp, which means it is possible that you'll get this in other free-flowing catless systems as well.

Typically, non catted setups are the raspy ones. I had an SLP loudmouth on my 02 Camaro SS and it's literally just a resonator. I had to add cats to it to get rid of a rasp at around 3.2k rpm I couldn't stand.

I'd love to hear some clips of catted front pipes with the unresonated Perrin. That's probably the sound clips I have not heard.

I plan to add a header to the car in the spring to go along with my Perrin catback. Because the sensor is in the header, I plan to keep the cat in the header and then run either a high flow catted front pipe or no cat. I plan to post a few video's in 2-3 weeks once I get my Perrin catback installed. In car, drive bus, and standing free-revs.

After reviewing few sound clips, the Perrin doesn't have the same deep tone sound level compare to the evo. It seem to me like if you stick w/ Perrin exhaust system then it give you either too quite or some louder w/ little of hash raspy tin sound kind of tone. Also regarding the design and look from the back, it look kind of ordinary just like stock exhaust w/ upgrade finished and add-on tips imo. Well, i'm still searching b/c it hard to pick an exhaust with good look, good sound w/ decent hp gain at the same times. I think Evo could be the best one out there b/c of the Evo look with serious sound when you need it at some times :)

Suggest you take a test drive in an Evo 3 equipped car to see if you're bothered by the unsilenced drone at 3K. Honestly, the Evo 3 is the best sounding exhaust for this car that I've found when it comes to really deep throaty growling exhaust tone. The Perrin is deeper than stock, but it is definitely not like the Evo 3.
