does the perrin catback with NO resonator drone at all?
 

thinking about going with perrin for my exhaust, catback will be as far as i go so i don't have to worry about passing inspection. wondering if i should go with the non resonated version or resonated. i've listened to clips of both and i like the way the non resonated sounds, i just don't want any drone or obnoxious sound from it if i'm just cruising.

this is for a daily driver

If you plan on staying strictly catback, I would recommend the non resonated version. You will not experience drone and will have a great sound as well!

I've had the Perrin non-resonated CBE for awhile now and I can attest to the fact that this systme has NO drone at all. I've been on fairly long hwy jaunts and bumper to bumper traffic and pretty much everything in between. I highly recommend it. Also, as a side note, at first the system will sound a bit louder, but will settle in and get milder so don't get alarmed if it sounds louder at first. :thumbsup:

I just put a resonated Perrin catback on my car and have a catted front pipe and over pipe waiting to go on too. Below 3500ish under load, I'm getting a LOT of drone, enough to to make stuff rattle. Have't had the chance yet to lift the car back up to check for leaks, really hoping there's just a leak and it'll quiet down once that's fixed.

I have no drone whatsoever on the Perrin non-resonated catback. And believe me, I know what drone is (I had the GReddy Evo 3 before this).

No rasp, no vibrations, nice quiet deep exhaust note at idle.

Something's wrong with your install. How much did your torque the bolts and the vbands? Make sure its not rubbing on anything? I thought I recall someone saying that they had some rubbing on the automatic transmission, but they were able to get rid of it.

no drone at all and a hell of a lot of noise once you put the throttle down, just how i like it.

No rubbing w/ the AT just some odd rattle that I'm working with Perrin to resolve. Even at that it comes and goes and is not TOO bad. It can only be heard/felt at a stop. Just to be fair, not all AT owners are experiencing this either, just a few.

No drone here, I have the Perrin over, front w/hfc, and non res cat back.

thats kinda what i'm looking for. if i'm just cruising and driving slowly around town i don't want it too loud. but if i'm full throttle i def want to hear it.

in car just driving around town at low rpm's can you hear it?

At low RPM it's similar to stock, just a bit lower in frequency, IMHO. It's almost too quiet for me, but I guess I got used to a louder system.

idk about foobar, but its loud enough around town below 3rpm that you WILL draw alot of attention. whether people want to or not haha.

to be honest its loud enough that i get embarrassed to go over 3 rpm in the city. nice to have that kind of volume laying before your feet.

keep in mind i also have the front pipe w/o a cat which increases volume a bit.

Yep, that's definitely a factor. I plan to eventually get the perrin front/over but I'm keeping a cat. New York would rip me a new one every year otherwise, and I'm certainly not going to be reinstalling my stock system every inspection.

I'd like to hear how this catback is with the catted Perrin front/over pipes. I bet I would be real happy with that since I already got used to the GReddy Evo 3 volume which definitely can gather attention fast.

what made you want to swap out the GReddy?

I was too sensitive to the 3K drone which was right at my highway cruising speed. The volume was not a problem for me - loved it, in fact, but at prolonged cruises I was getting a headache. I mentioned in other posts that some people are more sensitive to this type of thing than others. I wish I wasn't one of the sensitive ones as everything else about the Evo 3 was fantastic.

I can understand that. Anything much louder than the perrin I have now would definitely be too much.

Do you have plans to install the Perrin Overpipe at some point? Since you already replaced the front, you've already crossed the Rubicon as far as emissions are concerned. Might as well go all out, no?

yes, but the installation of the overpipe requires lifting the motor a 1/2 inch or so i've been told (not required per se, but really helps make install easier). which scares me even though i'm sure its not as hard as it sounds.

It was the v-band on the muffler. I redid all the joints, and while I was at it, found a bit of weld spatter on the muffler flange. Adjusted the band to clear the spatter (don't have any files handy) and everything was good. The car sounds much better, none of that booming drone under load, almost sounds stock puttering around until I give it some throttle.

Next gremlin to squash...Back edge of the head liner buzzing.

Hey foobar! Where in NY are you located? I would love to hear this exhaust in person.

Long Island, just east of the Nassau/Suffolk border on the North Shore. You're welcome to check it out if I'm close to you.

Oh okay, it wouldn't be a bad drive then. I'm over in Queens so I figure around an hour or less. I'm having trouble deciding between non resonated and resonated so I'm definitely interested in checking it out. Did you do any other mods aside from the exhaust that may have changed the sound of the exhaust at all?

Yeah, as far as mods that would change the sound, I've got the AFe/Takeda Intake and ECUTek tune, but these are things you would probably be planning on getting anyway. Let me know if you find someone with a resonated system, maybe we can drive out somewhere and do a side-by-side comparison.

Oh alright, sounds like a nice set up man. I do plan on getting an ecutek tune from fa20club but I'm still on the fence about installing an intake (the takeda would be on my list if I do). Setting up a comparison with someone who has the resonated system is a great idea though. I'll see if I can find someone.

I'm selling a non resonated midpipe for 150 if anyone is interested. Too loud for my girlfriends liking. Pm me if interested

The can also vouch for the no drone as I have the non resonated catback with overpipe and catted front pipe.

At first, the mechanic didn't tighten everything good enough and wooooo boy... lots of exhaust leak and I was sad that my system sounded like that

lifted the car and loosened, and tightened everything to my liking and all the "drone" exhaust leak sound poofed away. more driving down the line coated the pipes with exhaust soot and it's perfect now.

almost stock rumble at idle and cruising on highway, barely audible. I hear my tires more than my exhaust! unless I'm stepping on it of course :)

Try retorquing everything to spec first. Sounds like you might have a leak.

The non resonated pipe is pretty quiet if tightened properly. There have been a few reports of loud systems turning out to be loose bands or bolts.

Old ass thread but I have the same droning issue around 1.5-3k rpm. I just jacked it back up today to undo and re tighten everything. A bit of water coming out of fp and mid pipe connection but no air leaks. The tips are also poking out on the left side (drivers side) and not on the passenger. Any suggestions?
