OFH + Perrin 2.5 CBE

Can you hear the boxer rumble with the stock cat back? Have an audio clip?

I have an EL header, so no rumble. I don't like that rumble. .

However, because I already had the exhaust which I didn't install (due to laziness) I decided that this would be a good weekend to put it on.

My first impressions are...it seems loud. I'm pretty new to the car modding world, so I haven't installed an aftermarket exhaust on any of my previous cars. I'm not sure if I'm just not used to that sound, or if it really is as loud as I think it may be. I always hate seeing/hearing riced out Hondas with huge exhausts rolling around the streets, so I'm sincerely hoping that I'm not "that guy" now.

I would appreciate some feedback from other OFH guys who have an aftermarket CBE to see if it is actually loud to the outside world (comparatively), or if it's just me not being used to it.

Quick question, what did you get the exhaust for on Black Friday last year? I've been in the market for one, but might just wait until Black Friday. Did you buy it online or at a shop?

I had it sitting around so I figured I would throw it on and see what it sounded like. I had read that the perrin 2.5 resonated was almost identical to stock when the rest of the exhaust was stock, so I figured it would be just slightly louder than the stock with OFH. I was just surprised that the volume seemed to jump to be 3-4x louder than with stock cbe. I may end up taking it off, I was just curious as to others experiences with a catless header plus cbe.

it'll get quieter over a week or two of driving.

I dunno.. that perrin catback is a more mellow exhaust. i think he has a leak. you should post a recording

I picked up an OFH a few weeks ago. Before the header install, I just had a 3" Perrin resonated cat back. The exhaust itself sounded very mellow and I was very content. I installed the headers (ooopsies, didn't realize or just forgot they were catless) along with a catted Motiv front/over pipe. And yes, this sucker is very loud now.

Now...it doesn't sound like a tuba or anything ultra ricey. It sounds very aggressive and amplified. There's days where I love it and days where I drive it very gingerly to keep the notes to a minimum. I'm patiently waiting for my catted UEL to arrive.

(and supercharging definitely didn't help either)

I'm actually really surprised, I have the Tomei UEL and the Perrin CBE Reso. I know different header but i'm sure similar noise levels.

I literally have never had anyone say my car was too loud, my friends, in another car, were skeptical when I said was flooring it up a freeway on ramp. Skeptical that it was so quiet when giving it the beans.

Yes its more prominent than just a CBE or just a header but really its not "those" honda bee hive tin can noise in anyway.

EDIT: its probably a leak. Perrin's CBE is one of the quietest out there

It's barely noticeable.
Even with a catback and header it's really only noticeably rumbly in the lower rev range.

I can't remember the exact price. I wanna say high 600's for the resonated. I bought from fteightsix online.

I'm assuming the only place that this exhaust could get a leak is the connection at the front pipe? I only say that b/c I'm assuming if the v-bands are leaking it would be from defective tubing.

My recording would probably consist of throwing my phone in my back seat. I'm not sure if that would be super helpful.

I'm thinking I will give it a little time and see what comes of it. I had originally created the thread after putting at most 25 miles on the exhaust. As the week has progressed it seems like it has less of a metallic sound, so maybe it just needs a little carbon build up.

Put your phone on the ground next to the exhaust and rev it in nuetral

Like others have said, give it a week or two, the inside of the pipes will coat over, and it will quiet down. If you use an aftermarket frontpipe it might not mate exactly right to the header so you will get a slight leak or some knocking on the suspension bits. I've had that going on for a couple weeks and I finally got fed up so I have an appointment with my local shop to pound out the front pipe so they play nice. This OFH/Perrin combo is going to be one of if not the quietest you can get though, so if that is loud for you I don't see many other options.
