Refined Exhaust Note
 
I want my exhaust to be refined aggression.:thumbup:

I have a professional job and can't be RACECAR-ING-IT all the time, and that's not what I'm after regardless..

Current exhaust mods:

*HKS EL header, coated
*AVO over pipe, coated
*stock FP
*Invidia Q300 dual cat back

Basically want a setup that has some bite when I get on it, but doesn't drone or sound obnoxious at low RPMs. Current set up sounds a little bland to me. Quiet enough but bland. Want a sound that's a little more exotic..

My thought is maybe a UEL header would give me the little bit of ompf I'm after?

Any suggestions at all? What say you lads?

THANKS.

Dump the oem front pipe for a larger aftermarket catted or uncatted front pipe. Should be all you need.

When I put the TRD axelback on, the HKS header sounded very good. Although I had their R-Spec frontpipe too...

Do a stealthy V-12 swap while no one is looking.

HaXx 05-01-2020 11:43 PM
trade someone for their invidia N1. the minute you mess with your front pipe youre going be a straight up rattle tin can.

or sell me the hks EL and buy a UEL

Try HKS HiPower Spec-L instead of N1 for similar type but lower sound. Plus it is very light. There are youtube videos.

Just wait the Q300 will get louder over time, mine did. A little raspier too when on it. Not sure I love it with Windows open, windows closed cabin sounds good. Jdl uel catless header, jdl catted and resonated FP, stock overpipe.

DarkPira7e 05-03-2020 11:29 AM
I think the best refined aggression is factory exhaust with a catless header.

I actually think the opposite. I think my car sounded best with just a cat back and no other exhaust mods. I have a stock cat back, catless header, and front pipe with high flow cat now. It sounds like absolute garbage.

Agreed. I went:

Stock
Catless header only
Catless header + catted front pipe
Catback only

I’m never going back. Only stock and catback only sounded good.

That's why sound is subjective, and these threads never have a conclusion until OP comes to their own conclusion :) but it's fun to discuss anyway. Even with my turbo I had the stock catback and everyone that heard the car couldn't believe how refined it sounds.

Yeah, I know what you mean, it is subjective but I hate that really raspy noise. In all my in car videos the noise is actually tolerable, but the video takes the harshness out of hit. My car is really raspy, it sounds like a Honda civic modded after the first fast and the furious movie.

I did that once, Tomei header w/ stock everything else.

There was some really annoying rattle sounds coming from the stock exhaust under load on the freeway.

gpvecchi 05-03-2020 03:17 PM
A friend said that on his BRZ the key was to keep stock midpipe, if using a catless header. Any other combo he tried sounded ugly...

Strange, mine was nice. Maybe because I put on a 300 mile stock 2017 exhaust to replace my nasty 2013.

This is the problem with small sample sizes, there's no right or wrong answer. When piecing together exhaust systems piece by piece, you get too many different outcomes...

or some type of header system where the header/OP/front pipe was the same maker, and the catalytic converter + resonator are large units on the front pipe.

This way, you can run whatever exhaust you want.

jflogerzi 05-04-2020 12:24 AM
I think you should look at a JDL resonated FP or HKS dual resonated. Should pair well with your current setup and give you a bit more volume without getting to loud

My Q300 did the same thing! It's definitely louder and I would dare to say almost it's as loud as the R400 Gemini when I had it.

I know. Not that happy about it. Luckily I tuned out the cold start, otherwise waking the neighbors at 6:30am would not be good. I am not a young punk so I don’t want something ridiculous. Hopefully it stays where, it is. If it gets much louder I might have to do something. I would love to have someone repack it for me. Have not found who would do that at a reasonable cost.

Have you ever heard how that sounds from outside? It rattles like an old civic with distasteful mods.

It's actually bad enough that folks in CA get pulled over for it.

I swear to goodness mine didn't sound that bad. Maybe it helped that the header was CNT rather than expensive well thought out runner design, and UEL

Why does that happen? Starting to worry me because I just ordered a Tomei catless header.

No primary cat and much thinner metal on the header pipes.

I can confirm, even my stock exhaust + JDL header, which uses thicker steel than most aftermarket headers, was raspy from the outside.

longer exhaust sound waves that the stock muffler wasn't designed to muffle, because the stock cat handles that. These longer waves then introduce vibration, which manifests as a nasty rattle.

Specifically, the sound is that of any old car with a very rattly or tinny exhaust.

The CSG Touring86 will eliminate this problem while maintaining a mature exhaust note.

Am I right to assume that this rasp/rattle you guys are speaking of with an aftermarket catless header only happens if you are still on the stock catback? Or it will sound like that in general when you get a catless header? :mad0259:

I'm planning to install the Tomei EL header paired to a Perrin 2.5in resonated catback.

We're referring to the stock catback. The Perrin won't rattle.

mistople 05-06-2020 12:22 AM
EL header + stock FP + Perrin 2.5" resonated

ItsReiko 05-06-2020 01:24 AM
@mistople catless? Any pops on this setup? ;D

I run the Ace A350 which is catless. The stock FP obviously retains the stock cat. No pops or weirdness. Sounds very racecar :party0030:

I can attest to this claim. The ACE headers give it a very good sound

It's unfortunate that I can purchase two Tomei headers and still have $400 left over for the price of an Ace :cry:

jflogerzi 05-07-2020 12:40 AM
Look at JDL 4-2-1 EL cheaper than ace

Dont worry too much about what brand header you get. 80% of the gains are coming just from the fact that you ditched the cat in the header

Not surprised. Those are a totally different style of catback.
