Exhaust advice for deep rumble but not too loud
 

I'm looking for some advice on how to finish my exhaust. I want the deep boxer rumble without any rasp or drone, I also don't want it to be super loud. I already have a cat-less JDL UEL header and a stage 2 tune. The car is mostly a daily driver, with a few track days a year.

From watching some videos I like the sound of the N1 (with JDL UEL) at idle, but its too loud under power. It also seems like the 2.5" perrin is a popular option

What you're looking for probably doesn't exist. You don't get a deep rumble without being loud. The larger the diameter the pipe, the deeper the tone. But also 3"pipe will like to drone. "Tuner" cans are more inclined to drone too. Resonators will help with drone but it's not absolute. Cats will help with volume and drone the most but I dunno if you still get rumble with cats

This might get you in the right direction. I have that muffler and a 1320 uel and it fits this bill you're asking.

If you scroll through that post there are a few sound clips.

There is a name brand version of the exact axleback. I think it's the greddy but only comes as a Catback.

So you don't have to dig through the whole post.


Also I had my uel with an N1 clone and let me tell you that bitch screamed from 1300 to 3000 for daily driving shifting. It was stupid.

Turbo with uel manifold and 3" turboback.

Get a Q300

heres the deal, keep the stock front pipe, front pipe swaps do nothing but make the car raspy and tinny (or so the forum tells me)

at far as a catback: single exits are the loudest because all the exhaust gasses only go through a single muffler. next loudest are the N1 style (what i have), then the quietest catbacks are invidia Q300 style, where all the exhaust gasses pass through a central massive muffler before exiting.

Edit: when your going about town its nice to have a subtle exhaust, but when you step on it occasionally dont you want to hear it? its not like driving to the shops with a light foot is going to be obnoxiously loud if you keep a limit to your throttle

id opt for N1 style, whats the point of spending time and money putting on a q300 style just for a tiny increase in sound. get your moneys worth.

That is what I have and agree!

Exhaust advice for deep rumble but not too loud
 

Greddy Supreme SP catback. Deeep at idle and low RPMs, quiets down enough at high RPMs so you can hear the engine up front. Quiet, almost stock when cruising. It sounds perfect IMO, it's very well made and much more affordable than Perrin/Corsa. I’ve seen them for sale new for under $750 shipped.

The video unfortunately doesn’t convey how deep it sounds at lower rpms:

Disagree, you can increase the rumble while keeping it relatively conservative, but the tradeoff is more weight with the added packing material.

Magnaflow has a deep rumble, but is still pretty civil. Keep in mind that any exhaust you choose save the q300 will be louder than stock. Oh, also comes with lifetime warranty.

Thanks for the recommendations thus far. I'm ok with the exhaust being louder, I just want it to be civil and tolerable as a daily driver.

After reading the following thread I'm starting to lean towards the 2.5in resonated perrin. Thoughts?

Cant go wrong with Perrin. That and the TRD are two of the best if you wanna keep it civil.

I can confirm the TRD (at least the version I have) sounds throaty and amazing!

Keep in mind TRD mid pipe is actually smaller in minimum cross-section (about 0.25") than the stock exhaust. Before and after dynos are hard to come by, but I personally wasn't okay with spending TRD prices on something smaller diameter than stock.

I had the SP on my previous '14 WRX and loved it minus a warped flange. Does your system have the stamped flanges or the solid ones?

I thought about replacing my Corsa with the Greddy, but went with the Fujitsubo axle back instead.

Go V8

it has cast steel flanges like this:

I have the axelback version from Japan so I can either keep the oem midpipe or get an aftermarket from Works.

The picture isn't loading but I think I've seen them on Greddy's site.

Just remember a resonated front pipe to match.

Honestly for a daily I wouldn’t touch the front pipe. Do the catback first and break it in, most get a bit louder after a few heat cycles.

Corsa has a really deep and gentlemanly rumble

Corsa Has a very livable setup with the rest of the exhaust system stock.

Loud enough on throttle, hardly noticeable near stock at cruise. No drone, plus a lifetime warranty. Sound profile should never change which isn't the case for many fiberglass packed muffler setups. It's not a Base-y setup, more of a growl.

Perrin 2.5" is a subtle deep tone. Good future proof option should you decide to go catless later. It doesn't really rumble though with factory headers.

I know long over

This is the PLM UEL, stock overripe, HKS dual Res Front pipe and my stock TRD singletip axleback exhaust. Drones less than the stock front pipe did, still drones. It's bearable and quiet at idle but really opens up when I lay into it. Stays deep sounding below 3k RPMs cruising. I only know that because I like tunnels

I wanted something with a mature sound yet civil for daily driving and without any drone for long trips. I have the Lachute Performance catback (and full line) with the long resonator version, and it is perfect for my needs. I can drive it for hours even with the backseat down without any fatigue, and has a nice deep sound. Not sure it would be readily available in your area, but I thought I’d mention it, its a very high quality hand made exhaust, warranteed for life. I’ll see if I can get a sound clip.

Cheers

I recommend going to a car meet and hear it in person and decide accordingly.

The very best solution would be to find the most respected exhaust fabricator (not fitter) in town, the older the better, and ask him what he could make for you that can get close to exactly what you want.
With the right expertise ,it won't be the cheapest option, but it will be much better than anything bought off the shelf.
I should have done it from square one:

Here is my exhaust: Tomei UEL, Tomei overpipe, stock FP, Corsa catback

Cabin (window down halfway through)

I have a jdl cat less uel header and jdl catted and resonated front pipe. Just be careful with the Q300, the packing in mine broke down and it got ridiculously loud out of the drivers side tip. Too loud for an old man like me. So i took it off and I am riding stock until I get an axleback. I wonder if Invidia would warranty the Q300. I mean it’s loud, I love it on the weekends but a 120 mile round trip commute it sucked.

Can it be repacked? I'm sure you can buy muffler guts online

Q300 calms down UEL catless header nicely. just be careful with the tips, some rattle due to not being welded. if you drive normal its usually quite, and loud if you get on the gas.

I have TOMEI UEL headers with an X-Force 2.5’ catback. Rest stock and to me it’s perfect. Has an awesome rumble down low, but sounds like a race car when you’re up high in the RPMs (goes bbrrrrrrrrrr)
It’s sort of loud but only when you step on it. Cruising around it has no drone at all and is unsuspecting when you want it to be. To describe the volume output, windows down in a street where sound is being rebounded- it sounds loud when you step on it. But on an open highway it’s not that loud at all unless another car is driving along side you. I’ve never encountered any police problems with my exhaust setup despite living somewhere arguably stricter than what California sounds like, especially when it comes to modified cars and exhausts

With that said the x-force catback comes with a muffler valve so you can make it completely silent at the touch of a button (although I haven’t used it since I got the exhaust because it’s not as obnoxious as I was preparing for)

Me personally I’d like it to be a little louder just so it’s more noticeable in the low RPMs and Idle but definitely not necessary and wouldn’t be considering it if it wasn’t for the muffler valve

I put the FP back on, so it is fine right now. Still gets loud when on it but it’s not obnoxious.

Engine transplant - (55 Ford 292 cu in OHV V8 "Y" block), exiting through two glass packed mufflers.

Sound from an engine jest don't get no better sound than that - :thumbup:

I have Tomei UEL catless headers and a 3" Greddy Revolution RS Single exit. It's loud, annoying, and drones but I love it. Some exhaust companies sell silencers for their exhausts. I have one for my Greddy and it pretty much eliminates drone and makes it quieter in lower RPMs but sounds raspy as hell in higher RPMs. I'm currently working on putting a variable muffler (Varex) inline of my Greddy that way I press a button and its quiet and can have it full open as well. I'd recommend something like that as its hard to have a deep rumble without drone or loudness. This way you are in control.
