I bought a 91 Honda Civic Si over the summer. It now has a little over 191,000 miles on it. I was looking to do a little modification, and I figured the best (and most inexpensive) place to start would be exhaust. I was wondering what exhaust systems would be the best in my 4th Gen HB, and what everyone else here has in their rides. I hear good things about GReddy, DC Sports, and 5Zigen, but input from others is the best bet.

 

id suggest taking it to any midas or other muffler shop and they can straight pipe the thing, put in bigger piping all the way thru, install whatever muffler u want, get rid of or add resignators, a cat back system like those u mentioned are good but overpriced and in my idea not worth it, i had a whole new mandrel bent system put on my car with labor running right around 200 bucks, spent 100 on a stainless steel magnaflow muffler and i like it alot, nice deep sound.

 

That's true. 300 bucks vs. 500+ is a substancial difference.

 

make sure you pay attention to how long the muffler is you end up putting on before you buy it...a longer one will have to sit crooked...if that's what you want then that's cool, if not find a shorter one

 

we do a custom type deal for the crx, its slip fit and will come with all the hardware you need. you can pick out your own muffler or get one from us

only looking at fully mandrel bent catback around 185-215:

2.25-2.5-3" all available


that would be the first thing i do to the car. also check for any rust spots and upgrade your fuel and clean out the engine bay.. lot of grim can build up there

 

Now that looks like a good plan to me. I'd like the slip fit. Easy to install. I've already put a radiator, thermostat, and fuel pressure regulator in it. I also had new CV joints put in before I bought it. Now it needs new struts (I think) and new tires. I'm already starting to look at engine swaps.
