- Do catback exhausts increase horsepower? Acceleration testing of the Acura Integra after installing a catback exhaust. How much performance do you gain by installing a catback? This video tests how much acceleration improves with a Yonaka catback exhaust. The exhaust is also 10 lbs lighter than the stock system.

NEW VIDEO EVERY WEDNESDAY!
So engineers really do know what they're doing after all...
I'm looking forward to the Integra project videos so much. Keep up the great work!
I love what you are doing man. Keep it up. I would love to see readings like this for lightweight Crankshaft pulley or Lightweight flywheel. There is so much talk about these things on the forums we really do not know what to believe.
I LOVE your acceleration tests :D.. well all tests in general... well all videos about your Integra. more please. I will finish all the rest of them by the end of the day...
This is awesome, I basically have the same exact car(same color even) and I really like how meticulous you are and how well you explain what you're doing and explaining the results of your testing. I am also in the process of modifying my car(slowly but surely) and I had the same exact exhaust system on my list to purchase next and I really like how it turned out on your car. The sound it puts off is exactly what I was looking for and now I know exactly how it will help/hurt the car. Oh yea and now I know what problems I can expect when installing it as well. Maybe install a simple short ram or even cold air intake to help let that new exhaust show its potential and test the acceleration again and I'm sure you will see more significant gains from stock. Good work man.
any time you can make your engine breathe easier, whether its inhaling or exhaling, its good for engine power.
These testing videos are awesome. Keep up the great work.
I like the methodical approach you are taking with this.
Great experiment! Always worth watching your tests! Congrats !
Great job on consistent test procedures. I would encourage you to upgrade/ replace posi, clutch/pressure plate, and CV joints. One of the first things to go is going to be the clutch, posi ( if it has one), or CV joints... Only a slight upgrade on these parts ( stage 1 or 2 ) will make a vast improvement and make the car more consistent when testing parts and make ready for more power in the future.
Love this series man. Keep it up.
Excellent. Showing you dont need fancy dynos to baseline and track improvements.
thanks a lot sir you answered all of my questions you're a master mechanic!
Perfect example of how "easy performance" mods don't work no matter how much companies will tout "10 hp gain or whatever"(unless the system being modified is super restrictive, or they tested on a best case sinerio a.k.a modded vehicle). It's all down to how effective the engine is at moving air, because an engine is really a fancy air pump. I expect to see the same result when you get around to a CAI. Assuming no cams or FI are done before hand.
Enjoying this project, keep it up!
you should do an ECU remap for your next video! will be interesting to see what hp gains you could get from your now better flow exhaust system and a remap!
Man, I really love your videos, but I wish you would also make a "long story short" version of all of them.
Yet another awesome vid!
Think of an exhaust system as a multiplier. (Example, not actual stats)
I have installed the cutback on my toyota corolla GLI 2015 with 2000 cc and after some tests I found that the acceleration increased but fuel consumption also increased. This happens when I run the car in gear 2 thanks for your video
