To all Perrin exhaust owners
 

I am undecided on which setup to get so if you guys would be so helpful and provide feedback and/or videos, it would be greatly appreciated!

For example, how is non resonated compared to resonated?

non resonated with catted front pipe and over pipe?

resonated with catless front pipe and over pipe?

etc. etc.

sound quality? tone? loudness (too quiet, too loud)? rasp? drone?

just anything and everything with your experience with the exhaust will help

Also, looking forward to being one of the owners of this exhaust system! :thanks:

I don't own the exhaust, but a good friend does.

IMO, the resonated version is too quiet. I had a hard time discerning it from stock while in the car.

If you dead set on Perrin, go unresonated. It's not very loud, but at least you can hear a growl when you get on it :)

^^ Does he have the cat back, or the header back? The header back is apparently noticeably louder than the cat back.

He's got a catback. I haven't heard the headerback.

I think typical piece of advice is: if you're going ONLY catback, go with resonated. If you're going front and over and/or headers (when they get released) then go resonated.

You meant ONLY Catback, UNresonated, if going with more REsonated. :thumbsup:

I have the headerback:
+ Cat front pipe (Edit: I'm tired.)
+ Resonator

Note that I have not heard any of the other configurations of the headerback or catback in person.

Here are my feedback (I do not have an intake, drop-in filter or tune)
+ Idle is dead quiet. You cannot hear the exhaust even with windows rolled down. I do not want to attract attention while waiting at a light.
+ The system does get on with sound when you start off from a light. Frankly I think the sudden exhaust noise surprises everyone, and I love this.
+ Gears 2+ pulls harder. If you don't have a dyno (I don't) then this is the primary way you'll feel the extra gain.
+ When you are cruising, the exhaust gets out of the way so you can enjoy conversation, music, NPR, whatever your fancy. When you want to pass, it'll let you know you are passing.
+ It is a mature sound. No rasp, no drone, hissing, cam noises. Just a deep full sound. IMO this is not exotic car noise.
+ I think this is true of any exhaust; it'll let you hear your blips when you rev match downshift. In the end I think this makes you a better driver.

Loud exhausts are annoyin. +1

Hit the nail on the head here! :)

Thanks for the feedback guys, I think im going with @F1point4 's setup as I think his impressions with the exhaust is exactly what im looking for

That's the reason I switch from SRT to Perrin! Can't wait to install it this week!

i'm non resonated and catless and love every second of it. not too loud but very powerful sounding. like a beast waiting to be unleashed idk.

but having one sound dampener of some sort might be a safe route to go as it wouldnt be too quiet or too loud.

edit: also, because of the extra sound, its a bit easier to save gas as you can be more aware of how much throttle you give.

anyone has cat front pipe with non res cat back?

would love some feedback on this. i'm leaning towards this setup.

thanks

I'm curious about the opposite, resonated cat back w/ catless front pipe.

Check out my sound clips here:

http://www.ft86club.com/forums/showp...49&postcount=3

all are clips of the cat-back, no over pipe or front pipe.

I was at first too, due to @Sony 's sound recordings, the non resonated sounds more... free flowing if that makes any sense

maybe i might get this set up, post some pics and recordings, and let you know my feedback

almost have enough money saved up for it so it should be within a few weeks

I have the Op non catted FP and resonated Catback and its bomb. Sounds mean when it wakes up cold start and after it warms up its idles quietly. When you punch it, it sounds like how boxer motor should sound. Can't wait for tune :)

maybe you can post a video?
how loud is it for you?
maybe too quiet?
and rattles with the res catback?
might help for those still looking for setups as i know for it fact it might help me haha :happy0180:

Would definitely like to hear a test pipe w/ Perrin resonated set up if you can do a decent recording. That is what I am leaning towards but I don't want it too loud or any drone at normal cruising speeds...have had loud exhausts before and want this one to be fairly take until I get on it.

I'm looking to go with a catted front pipe and resonated cat-back, but I might do a header as well. The resonated catback with stock front and midpipe is too quiet, IMO, but I think the unresonated catback sounds too tinny/obnoxious, so just gotta do the whole thing.

what do you mean by tinny and obnoxious?

I have to use my cousin's go pro when I get the chance.

The sound is just right for me. Quiet when it need to be and loud when I want it to be.

As for rattles, rasps and drones; none. Beside the flexing of the resonator pipe touching the chassis (which I fixed).

Plus the customer service from Perrin is top notch.

Alright, thanks man! How exactly did you fix the flexing? Did u have to hammer the chassis as well haha... do you have automatic or manual

I installed mine and do not have any clearance problems, mine sits about 3/4 of an inch away from the tunnel wall. Really it depends on how the front-pipe was adjusted at the factory. You can readjust it yourself if you have issues.

Good to hear. I'm planning on getting the Perrin headerback (resonated), but the clearance issues were worrying me. I'll probably still wait a couple more weeks just to see how things go with the few members having issues.

You'll have to look in the members' rides section because I forget who has one but he posted sound clips of inside and outside the car and I gotta say I didn't like it one bit. I have a big loud stupid exhaust on my MR2 and I hate it; some people like that noise but I've grown tired of not being able to hear my music or hold conversations with people.

I just replaced my muffler delete with a Perrin resonated catback yesterday. There were no interference issues nor do I think there will be any though I do need to go back and realign the tips this weekend as the driver's side is a bit out "out" than the passenger side. Also, its silly quiet, too quiet as its nearly OEM quiet. So much so I ordered a midpipe today ahead of schedule. If you only are planning to do a catback, do not get the resonator IMO.

Is it at least noticable when you hit the throttle? I don't want a loud exhaust, but I do want something I can hear when I decide to go WOT.

Honestly its a toss up what's making more noise, the stock intake resonator or the catback. It is very quiet, just marginally louder than stock. IMO if you want that quiet, just get new tips for the stock exhaust. I don't like a very loud exhaust but this IMO without the midpipe which apparently increases sound by quite a bit, isn't worth it for most and they should go unresonated. Luckily that was always my plan so I'm not disappointed.

I installed the full Perrin header back. First impressions. It was loud on a cold start. But when it warms up and you just let it idle. It's a quiet deep rumble. Extremely satisfied with it. Wouldn't look at any other set up.

The other option is leave the stock catback and change the midpipe:

Not my car.

My car with the stock exhaust header, overpipe and midpipe with the Perrin resonated catback is not as loud as these videos, its more quiet to maybe give you a comparison point.

What's your setup? cat? catless? resonated? non res? etc :thanks:

Oh course the Perrin catback isn't just for sound...it's supposed to provide a nice increase in power.

Like you, I'm hoping to do the frontpipe+ at some point so perhaps the volume will be perfect (not too loud and not too quiet) at that point, with the resonated catback.

Catless, over pipe, front pipe and res. mid pipe. Love the sound. Loud when I want it to. Quiet when I need it too.

quick question to anyone, If i go catless front pipe, would i fail CARB? trying to dig up info but it's not coming up :thanks:

Yes.

We'll find out about that. I get my Motiv test pipe on Tuesday and might dyno again fairly soon after that to see what it did with those two pieces vs a muffler delete.

Catted front pipe is good if you ever go to uncatted header...

IMHO the cats help keep making power down low, if daily drivability is a concern
sure you may gain a few hp up top without a cat but it can get stinky too, and much louder

I think the ticket for headerback:
Overpipe,Catted front, Nonresonated Mid(theres little to no power penalty for the resonated mid if you prefer it on the quieter side of free flowing exhausts) to the can. The perrin can is nice and flowy yet where most of the sound gets and a bunch of resonance gets trapped, vs the louder dual smallerish-can offerings.

for (not too loud and not too quiet) get the resonated

most dyno stuff I have seen - the muffler deletes arent that impressive , but I am sure curious to see what you produce

when you said your exhaust setup was "more quiet" what did you mean? like is it stock porsche cayman loud? or like those 350z/g35s

also, looking forward to the dyno :popcorn:

With the rest of the exhaust stock and just the Perrin resonated catback, its nearly stock BRZ/FRS quiet. Extremely quiet compared to what I expected. I expected/wanted more quiet as I will be adding the rest of the exhaust pieces. Its probably about as loud as my stock Porsche Boxster S was so yes Cayman stock quiet.
