again for Racing Beat headers, but I didn't like their mufflers. They are very quieting but are very well built. I have a Magnaflow with a glasspack and no cats and its great. Low rumble at idle and loud and crazy with throttle. Make sure you get something that can handle the heat of rotaries!!

If you want loud then just run straight pipe. On an NA rotary, the louder you get, the more you lose low end torque and power. I ran open header for a while and trust me, you get nowhere in a hurry. You get more power out of a well tuned exhaust system. The freeist flowing isn't always the best for power when it comes to NA. My SA currently has an RB header straight piped back to an RB muffler. Very nice to drive around daily and when you stomp on it, you will get noticed. The plan for my FB is an RB Road Race header to a presilencerless dual center section to the RB Streetport muffler.

This is for the muffler:
MSRP: $266.39
PART #: 14815
DESCRIPTION:
Inlet/Outlet Size: 2.25in./3in.
Body Shape: 5in.x8in. Oval
Core Size: Dual 2in.
Body Length: 14in.
and the rest is a 14" glasspack (pretty standard at a muffler shop),
Racing beat's Cat-delete pipe,
and Racing Beat Headers.
Total I paid:
RB Headers (used): $100
RB Cat Delete Pipe: $150 shipped
Magnaflow Muffler (14815): $266.39
Install was about $150 but the guy did a great job welding it up. You will definitely feel the power top end. Hope this helps

I'd say with a K&N Air Filter and this exhaust, at least a 10% increase over stock. With only 100hp to start with, thats still a pretty good jump. Exhaust is the first thing performance-wise for rotaries. You will feel the power up top for sure and this will scream up top. Set off car alarms, shake windows, drown out any good sound system, and shake change out of other people's car. But if you need it to be quiet, just be light on the gas and you'll be ok
Here's it at full power to 70

OK. Sounds good. I am only looking for a Honda beater for my first car. I am doing a mayjor weight reduction to the car so it will be really light weigh.
low weight+ hp=speed
Catch my drift?
Haha i just watched that video like 2 days ago. Do u have any porting at all?

no, but i had some carb work done. Search "mechanical Secondaries", "direct Fire ignition S5", and you should be able to find some cheaper mods that free up some hp.
The mechanical secondaries is where the secondaries on the 4 port nikki carb (stock) are opened mechanically versus a vacuum. This gives you more response and it kicks in like (honda terms: vtec). With this exhaust you can really get it to scream.
Second the direct fire is talking about taking the leading coils from a FC S5 motor for your leading spark. This will give you better spark and give you some more HP.
Also if Look for " rats nets removal". This is talking about all of those crazy hoses and vacuum lines next to the carb. It is all emissions stuff and when properly removed along with the smog pump gives you some more.
These little things will help and has given my car a boost for sure. Maybe not as much as a port, but you will be able to feel it. Good Luck and Search Away!!

The s5 coils are discussed here: https://www.rx7club.com/showthread.p...hreadid=243350
and the mechanical secondaries is a mod, rather than a part. I would email rx7club member RW-7. He did it for me and would know more about it.

So i take it your to scared to do the porting...no problem...that racingbeat setup is nice but not worth the money...Your lookinf for loud...it won't be racing beat mufflers...The intake mani with the carb package is way too much...
1. Buy there 12a intake manifold new for $245 or used for half the price
2. Buy a holley 600 vacume seconds from jegs for $245-260...Do the math you save little over $300 bucks...
3. Buy there header 2 to one and run it from the header back 3inch's up and over the rear end and mount a HKS Hypersport Muffler...3inch inlet 5 inch outlet...Great power gains...loud at idle loud at full throttle...I ran this setup on my SA...
