420A 1999 420A exhaust

[2gbry]

I really want to upgrade my exhaust from stock and want the car to sound more fun. What exhaust are y'all running or recommend? It would be cool if y'all upload a video of what y'alls sound like as well

There aren't a ton of options anymore. At one point there was a long list to choose from, but now it's quite small.

I ran a Yonaka system for a few years. I enjoyed it and the tone was nice. Deep and not hollow.

If you want something louder you can still get cheap systems on Ebay. The tips are usually ugly in my opinion, and they sometimes have an issue of rattling against the rear subframe. That can be fixed by cutting & welding one of the hangers a little lower.

If you aren't looking for a bunch of shiny pipes or mandrel bends for that minimal performance gain, you could always choose a "universal" style muffler to replace the stock muffler with. There's still plenty to choose from in that sense.

Still using the stock convertor and practically only bolt ons, here's a (quick) video of the Yonaka system shortly after install:

Here's a slightly longer & more recent video, with more revving in this one. At this point p&p cyl head, oversized valves, stage 2 cams, high compression pistons, and a test pipe. A bit noisier but it won't sound quite this way bolted to a stock engine with convertor:

At some point Yonaka switched the pipe size to a 2.25" ID. The system I purchased was 2.5" ID. It's still a good size for N/A 420A. The stock system shrinks down to approximately 1.75" ID on the harsher bends.

I'm not a Yonaka salesman, but unless you want the cheaper raspy stuff with fitment issues, the more expensive stuff that is pretty much the same thing, or the $650 Magnaflow system: just spend $350 on the Yonaka system and enjoy it. Or choose a muffler with 2" inlet and have it welded up. That could be cheaper or more expensive depending on muffler choice, exhaust tip choice, and labor charges from your welder.

On my non turbo Hondas I normally choose the muffler I want and have it welded up. In some cases it's cheaper, in other cases I spend a bit more but get exactly the sounds and look I want vs some cookie cutter systems with limited choices.
