FULL 3" Downpipe & Exhaust System Install // 9th-Gen Civic FBO Part 1 of 4

Instead of liking this video.. How do I love it Milan? You're the best inspiration to building my (New to me) 9th Gen Si and you know how to do it right. Much love from CALI!

[@milanmastracci]

Thanks brother! I appreciate the love 👊

[@tylerritchie6579]

I'm just curious as to how he found a 9th gen that is SOOO clean

[@Zuudoh]

man i love how you do videos. you talk about what you yourself have planned as well as giving a proper, straight forward explanation/demonstration

[@tylervitayanuvatti5511]

Man you make it look so easy. I started at 9am and finished at 6pm. Everything was rusty, some bolts eventually snapped but the dp bracket had to be cut with a sawzall to get that section out

[@pinkstars2185]

I've watched this video like 5 times and I'll never get over how brand new the engine bay looks

[@kwckhm7757]

Brother this has got to be the most in depth video to date I've seen and I've seen ALOT. Even though it's a simple exhaust swap the way you explain it could have my kid who has barely touched a wrench know exactly what to do. Great job!

[@tomtomburke22]

Heads up to anyone buying this car. These transmissions tend to have bad synchros and sleeves, coupled with a weak second gear. Milan has a great video on the ktuned Clutch master and slave replacement. That along with shifter bushings is a must with this car. Honda hit me with a 15,000$ repair bill on a bad transmission (I don't even know how that's possible as the replacement trans is cheaper), and they refuse to cover it as there's no proof (I have a video posted to show the shavings in my trans fluid). That's why I'm super stoked to see your video on the clutch replacement and transmission removal. Our power steering rack doesn't like to come off the subframe up here in Canada from the rust due to road salt. Anyone has experience or good pointers to aid with this? Or is dropping the rack with the subframe the best bet? Props to the best video tutorials on car parts, you manage to make everything easy to see in the shot, and easy to follow.

I love watching your content step by step it’s amazing how much one learns hearing you explain everything , Ty 🤝

[@tomtomburke22]

If you're getting the hasport mounts get the 70. I got the 62 and it's much much better than stock. But still a little soft. The vibrations and noise are almost the same between the two. And yes it will shake a bit at first. Calms down after a month of driving. It still vibrates a bit. But it's not crazy. Approved by my family who hates loud/modified/aggressive feeling cars. It's the best first mod in my opinion. It's cheap, easy to install. Car is way more responsive, and it's a little louder. Makes the car feel more sporty.

[@milanmastracci]

I appreciate that feedback Thomas! 👊 Do you still have the 62 in your car or have you swapped it out?

Love the sound of my full race catted dp with q300.

[@milanmastracci]

Got a sound clip?

[@TheJanz3n]

I had a similar setup on my 9th gen. Full race catless downpipe and yonaka exhaust. The drone at 2500 - 3500 was unreal. Recently sold the exhaust and went back to stock. The 5% power increase with a full 3 inch exhaust wasn't worth the drone.

[@ThatBoosted9thGen]

you should go w/ a q300, barely any drone

[@milanmastracci]

Tbh, its not that bad. Maybe because I'm used to louder cars maybe, but I could daily drive with this setup no problem. You're back to full stock exhaust?

[@TheJanz3n]

@@milanmastracci mine was just awful. It shook my brain. It also got worse after a year of driving. I think the drone was louder than the exhaust note outside the car. I put the stock exhaust back on with the full race down pipe. It's still louder than stock but no drone. I debated getting a q300 but all the KZbin videos sound the same as the yonaka with no cat.

[@TheJanz3n]

@@ThatBoosted9thGen every video of a q300 with no cat sounds the same as the yonaka with no cat. I don't want to spend the money on another more expensive exhaust and have the same drone.

[@roberthunn2370]

Sup friend , impressed by ur mechanic skills and knowledge. Ik the 9the gen civic lx 1.8 and the si are a lil different in the placement of the throttle body, was wondering if doing a cold air intake would be possible with out causing map sensor readings and the car running even shitter. Just a wonder before I tear into it this morning. Thanks bud , by the way I are probably the only person I’ve subscribed to, I’m not a very great computer person. Wrench on, Rob

[@donavenlandry366]

Just wondering if you have any complaints about the k tuned catless downpipe? Any bad hissing or unwanted noises.

Tbh I think it is leaking from the top mounting position between the cylinder head flange and the downpipe. A 1 piece design would be best IMO. Performancewise, I've had no issues with it.

Hello, I also put a 70a hasport bracket and inside it shakes and there is more noise, but I don't know if I can make a video by placing dinamate, which is an isonirization of sound and vibrations. I don't know if that helps, I want to install it but I don't know if it works. Very good video I made modifications equal to yours and it is worth doing it only that I have a problem with my throttle body of the grams brand it sends me a factory error that cannot be solved.

[@milanmastracci]

Hey Albin! Dynamat will help a bit with reducing some noises and vibrations, however most of them are actually from some of the things you keep in your car, like keys, change, personal belongings, etc. Have you tried doing a throttle relearn procedure? Maybe that will help!

[@albinquintero5969]

@@milanmastracci Hello, could you explain to me how to do that re-learning of the accelerator, I tell you that it is very uncomfortable, you cannot have the car like this for a long time because it sends me that error and I chose to buy the k-tuned, they have told me that they do not have that That fails, I hope you help me please with the problem I have with the acceleration body brand grams.

Great video Milan ...It would be really really interesting to see porting and maybe cams I think you will get good results... also when you were cracking the bolts I saw a magnet on the oil filter do they work ????

[@milanmastracci]

Yeah that would be!! From what I've seen, they do. I have the same filter magnet on my 370Z. Metal particles floating in the oil will get attracted to the magnet in the filter, and when you do an oil and filter change, all of those metal pieces will come out. I want to cut one open to find out how well they work.

[@dhalesoliven1239]

What do you mean about retuning it after you install your exhaust? Did you put a different tune?

[@milanmastracci]

I did! Ideally, with every hardware change to the engine, you would want to revise the tune for it so you get the most amount of power from those mods.

Something gotta give if there’s no flex on the suspension or the motor mounts. It will destroy axles and transmission

[@thomascanning595]

I doubt it will…

[@gedas3419]

actually constant wheelspin is a lot better for longevity, rather than that hitting noise during launch. It grips up, it tenses up the suspension rubber, it tenses up the engine mounts, only then it spins "torques-up" the wheels, when torque breaks traction, then it releases that tension like slingshot, and again tenses, drops tension, tension, no tension. Actually that play IS DAMAGING. That's why drifters Solid aluminum mount their rear subframes, have Heim-joints in suspension instead of rubber, and after full day of clutch-kicks on 265's semi slicks, they get home without a single broken axlehalf. Imagine drift car go entire drift doing CH-CH-CH-CH-CH sounds NO.
