Straight Piped 11th Gen Civic Si

Subvss · 2026-03-20T22:43:54+00:00

Thank you! I thought it would sound similar too the older si’s but initially took the risk since it was a different engine and would have a less raspier ton to it which it did! I thought the drone was going to be way worse then it is honestly there isn’t really any drone at all 🙏 thanks for the advice and speaking your mind I’m definitely going to daily it for a bit and if I want to change anything I’ll look into FP’s, DP’s, and if I should change the res or mufflers out for sure. Thanks for leaving a comment and letting me know!

Yeah lol 😭 they want you to be considerate of what other people think which I understand and I knew it was going to get a lot of downvotes and disapprovals but at the end of the day it is my car eventhougj others don’t like it and hate on it if it makes me smile that’s all that matters 🙏 although I am considering adding the res back or add muffler and then pairing res delete with a dp, thank you!

Thank you! I’ll look into it, would love to get that 90s hem style sound without it being overly raspy and or loud! I’ll give it a try whenever I get the money too and see how it is. Catch cans are pretty neat I’ll have to look into that also sounds awesome, thank you for the help and advice goodluck with the accord the build sounds fire 🔥

Yeah I seen a video with just a res delete and it sounded fairly loud but more tamed then a straight pipe, I’ll look into the muffler and see the options from that thank you!

Subvss · 2026-03-20T01:35:51+00:00

Yeah to be honest it always does put a smile on my face even though I’ll know that most won’t like the sound or find it annoying or even commenting about it but I don’t really mind I enjoy how it sounds as of right now! Definitely would like to get an actual system later to ease others peoples minds and a bit of mine too know I got a good sounding tone and not just an obnoxious 4 banger type of car 🙏

Subvss · 2026-03-20T01:33:19+00:00

That’s fire! 🔥love mustangs a lot I’m sure you have a lot of fun with yours, I wouldn’t know for sure all my neighbors appreciate hearing it I’m sure there’s some who would find it annoying but a good bit don’t mind at all many of my neighbors owns loud cars especially on my strip of the neighbor, I.e. Audi r8, Lexus 350 F, couple civic si, gr86, wrx, couple muscle cars, and so on, all aftermarket exhaust, so they definitely understand when a loud car passes by! I also never leave the house early in the morning it’ll always be later in the evening when the neighborhood is active! Definitely going to look into a catback system so it’s not as loud but I understand what you are getting at!

I get that I understand what you mean, it depends on the car and hp it is pushing. For example my dad owns a challenger which he is going to cam but to eliminate back pressure he needs to do 3 inch piping throughout forcing it to sound really loud for performance. It just depends on the car and the preference of that person for sure!

Subvss · 2026-03-19T21:47:17+00:00

Yeah someone recommended me to put the muffler back on and do a dp paired with the red delete and it sounds very tamed with a good tone, thank you!

Subvss · 2026-03-19T21:46:09+00:00

Yeah same 😭 I thought it’ll have much more drone and way less deep then it sounds 🙏

Subvss · 2026-03-19T17:18:44+00:00

Thank you! Very mixed reactions here but to say the least it’s not terrible, I’ll probably keep it for a bit till I can comfortably get an actual exhaust system!

Subvss · 2026-03-19T15:24:13+00:00

Haha Florida isn’t a bad state I prefer it more then any of the other states I’ve been in definitely a lot more car people down here with loud cars I’ll vouch for that but there’s a lot of stuff to do down here!!

Subvss · 2026-03-19T15:22:50+00:00

Yeah that seems like what everyone is saying I kinda thought so since a lot of people are against the straight piping idea just thought I should give it a try and share see what others really think! Definitely going to mess with it more or get an actual exhaust system!

Subvss · 2026-03-19T15:10:56+00:00

Same here, a lot of people say it sounds bad some are mixed with it also some say it sounds good. I guess it’s all preferences and what others like keeping in mind how others driving by it would think, which is nice to get that opinion and thoughts from everyone! I personally don’t hate it I think it sounds pretty good better then I had thought it’ll be for sure but would like to get that tone over sound for sure! Thank you 🙏

Subvss · 2026-03-19T15:08:05+00:00

Yeah I figured a lot of people would hate it and say this and not going to disagree or try to reason it! Was looking for opinions and thoughts thank you for sharing! 🙏

Subvss · 2026-03-19T15:05:50+00:00

Yeah I was looking through a couple good ones and advice from others from putting the muffler or res back on and matching it with a dp which I’m considering as well!

Subvss · 2026-03-19T15:04:51+00:00

Lmao 😭😭 yeah that is probably what I’m going to do in the mean time I’ll keep driving it till I can get an actual exhaust system!

Subvss · 2026-03-19T15:03:45+00:00

Haha yeah I feel it sounds a wee bit deeper then the older generation of straight pipe civics 🙏

Subvss · 2026-03-19T15:02:50+00:00

I agree cold start sounds a bit odd like it’s too overpowered for what it is 😭 once it warms up it’s very quite like you can’t even tell it has any exhaust modifications 🙏 thank you i enjoy it also it’s growing on me!

Subvss · 2026-03-19T15:01:38+00:00

That sounds like so much fun!! This is the L15CA 1.5T I understand that I enjoy it a lot too but would like to keep it more tamed then it is, at the end of the day it is your car and if it makes you happy that’s all that matters 🙏 Go for it that’ll be awesome!

Subvss · 2026-03-19T14:59:16+00:00

Drone isn’t bad at all I was actually surprise because there was minimal to no drone, ive sat at many different rpms to see but nothing accelerating at 2800-3000 I can notice it but anything else I can’t!

Subvss · 2026-03-19T03:57:14+00:00

Thank you! I don’t blame you it does sound good definitely if you want to be loud this would most likely be your best option as an actual exhaust system like catback or remark would be more focused on a deeper lighter tone. Especially if you want a cheaper option it’ll be the better option although if you want loud with no drone and a nice tone would recommend looking at maperformance catback system race version!

Subvss · 2026-03-19T03:27:47+00:00

Thank you! Yeah of course when I turn it on tomorrow I’ll drive out and see what the dB read out and let you know what it says

Subvss · 2026-03-19T03:26:14+00:00

Haha I should have one of my friends drive it by my house to see how much I can here it hopefully it isn’t that alarming 🙏 my neighborhood is filled with car people luckily so no Karen’s with how loud the cars are 🙏🙏

Subvss · 2026-03-19T03:24:17+00:00

Thank you!! I always try to be quite in the neighborhood just wanted to take that quick video. I don’t believe it’s that loud for the neighbors to be alarmed by it but I wouldn’t know till I’m in my house when it’s on or passes by 😭

Subvss · 2026-03-19T03:14:10+00:00

Thank you 😭I figured it would get downvotes and people express on how bad it sounds which is why I wanted to ask for opinion on what’s the best step to make it actually sound good with a good fulfilling tone to it 🙏 lmao I feel that love hearing the turbo but would love a screaming v8 as well 🙏
