Deciding between aftermarket exhausts

4431 Views 28 Replies 15 Participants Last post by  Chilly613
Hey everyone, I want to put an aftermarket exhaust on my si but I'm having some trouble deciding. I have 3 options on my list currently the first is the Remark exhaust, the second is the Magnaflow neo series, and the last is the 27won exhaust. I don't want it to be overwhelmingly loud but I would love just a little more sound than the stock has. If you have any other recommendations and suggestions I'd love to hear them. The links for the exhaust systems are here for easy access. Thanks

Remark exhaust: Sports Touring (LINK LOOP) Catback Exhaust - Honda Civic Si FE1 (2022+

Magnaflow Exhaust: MagnaFlow NEO Series Cat-Back Performance Exhaust System 19600

27won exhaust: 2022+ HONDA CIVIC Si/2023+ INTEGRA FRONT-PIPE BACK EXHAUST SYSTEM

Do you have a sound clip you could post? I go back and forth between wanting to get the megan racing vs remark, but there isnt much to go off of for the Megan racing exhaust. Id appreciate it

Yes I will post. The Megan racing and remark are complete opposites sides of the spectrum both on looks and sound. Megan is very quiet and very close to stock. Remark is considerably louder, just under the Magnaflow in regards to sound.. a lot more pops and gurgles. DC sports and borla have released an exhaust if you want to check those out lol. Don’t think I’m helping in your decision 😅

Thermal R&D has an exhaust system for our cars now. Theres at least one video on youtube that i watched the other day and it sounds great in the video. They also state that they use drone cancelling mufflers which is nice. Not nearly the same vehicle, but I had a Thermal exhaust on my old 4th gen prelude and it was easily the best sounding exhaust I've heard on that particular vehicle. The price appears to be competitive as well.

I opted for the Spoon N1 for my 2023 Si. Spoon USA is saying there is a 3-5 month lead time. Won't know how it sounds for a while yet.

Sounds good. Looks like decent quality welds but what's with the section clamps?

A lot of companies use compression clamps for exhausts, its no different than using couplers for intakes. Keeps the cost down as they dont need additional welding.
I have a DC Sports exhaust on order. The reps say it should ship mid June... from what I've seen it looks more "grown up" or maybe cleaner or less boy racer which is what I want. The sound seems louder than stock without being loud. We'll see. I looked at the Spoon but it seemed super quiet and the price is crazy. I was really wanting something with black tips. Like the APR I had on my Mk7.5 GTI. But there's just not a ton of options right now.

Unsure how it would hold up in rust belt / Ontario winter climates. Most of these aftermarket parts were never designed for road salts since most of the companies are based in CA/NV

I would recommend MAP Performance's exhaust then, Theyre located in Minnesota. It gets cold AF there lol
