What's the best sounding exhaust with the best power gains? Any body have any videos of their exhaust set up?

do some research. There's alot of info and oppions on that in this forum.

Depends what kind of power gains you're looking for and what sound you want.

Many will say racing beat but it is pricey. The rest depends on if it is a TII or N/a and if you like loud or moderate toned exhausts. Power gains arent just from the exhaust. For example if you have the original air filter that is likely clogged with leaves and debris then you will have little or no power gains. The rest of the power gains are from other mods that the exhaust will allow to function. Such as on a turbo car if you add a 3 inch turbo back and a good air filter setup and have a few other supporting mods then you can increase the boost.


Also as always maintenance is the first modification that should be done. Such as all fluid replacement and all filters.

as for sound clips try youtube.

i personally like the greddy power extreme exhaust. it has a really nice deep tone to it, as for power gains i dont have a clue. its a bit pricey but i think worth it.

and yea it does depend if you have na or a TII. NAs tend to get really throaty and ricer like same goes for TIIs but not as much. you dont wanna go larger than 2.5in on an na or else youll lose some power.

if you have an na go with a borla or rb
for a TII rb or the greddy.

It's a TII. And I am aware that other things support the exhaust power and potential. I like the sounds of the Racing Beat but it kinda of pricey. But I am wondering what the power gains for a TII with the full Racing Beat set up, since the site claims its a 60hp gain. Seems quite high for an exhaust. But I will look into the Greddy.

A search will definitely help, but the RB exhaust allows the boost to increae to @ 10lbs, that's where the HP comes from. Install a MBC, increase the boost and save money, but, as with any increase in PSIuld, nstall a larger fuel pump, a FCD, and I would look into larger secondary injector if ypu're not looking for any electronics upgrades.

Personally, I love the sound of my RB's. Bought the car with them and I don't think I'm gonna change it.

My TII had a gutted pre-cat and custom catback 2" mild steel Y-pipes and no mufflers, and it sounded just fine. Unlike a non-turbo car, you can get away with this because the turbine soaks up a lot of noise. It cost me about $200 at the local muffler shop. However, you would not be able to do this if you have an aftermarket downpipe because it would be too loud.

The Racing Beat exhaust is very well made and sounds good. I would not consider $850 pricey for the entire exhaust since Rotary Performance wants $800 for the GReddy catback alone.

You could probably piece together a full exhaust by using a Corksport or Apexi catback, or maybe just some Apexi mufflers, but most of the experiments I have seen like this end in a very loud disaster due to cheaping-out on the custom components.

A full exhaust like the RB unit will at least require a FCD and boost gauge, and an upgraded fuel pump is also a good idea. The engine will NOT run correctly with upgraded secondary injectors unless there is an electronics upgrade of some sort.

What problems? I've never experienced a problem with any of the TII's that had upgraded secondary injectors. Similar to increasing the pulse width of the stockers with aftermarket electronics, but a great deal less expensive.

Evil Aviator

It is a problem with resolution in which the engine will not run correctly. Sure, the engine will still work, but the tune will be off. In most cases, the engine will run rich in the higher rpm regions, which will cause bogging.

Top-notch standalone EMS: 64-128 adjustment points
Good standalone EMS: 32 adjustment points
Good fuel computer, cheapie standalone EMS: 16 adjustment points
Cheapie fuel computer: 8 adjustment points
Upgraded secondaries with no fuel computer: 1 adjustment point (fuel injector size)

With fuel computers available for under $400, there is no reason to upgrade fuel injectors without adding the proper electronics.

Agree, but speaking of tune, going back into the 80's and 90's the RB exhaust was added along with a FCD without any other upgrades and the little rotary still chugged along giving the owners lots of fun in the 10 lb. area. Add in larger secondary injectors and it flew without any ill affects. They blew up then and they blow up now.
Even aftermarket computers should be checked after installation to see if proper fuel/air ratio as the ecu will be for a generic setup, but as we all know everyone has different accessories on their cars, e.g. intake, exhaust, emissions etc.

Sure, if money no object, go standalone and have tuned, otherwise...........

Evil Aviator

It's still that way, but you also need an aftermarket boost gauge because the stock gauge doesn't work with the FCD installed.

Larger secondaries had ill effects then, and they still have ill effects now. There were other similar ancient ghetto mods such as the rising rate fuel pressure regulator, or modifying the spring in the AFM. The more common 1980's vintage AIC (Additional Injector Controller) was a little better, but it was still pretty lame by today's standards. Yes, people blew their engines then and now mostly because they ran too much boost or didn't realize that you can blow an engine by running it too rich. Nothing has changed in this respect.

... otherwise don't mess with the car unless you have the money and/or skill to maintain safety and reliability.

For example, if the OP can't afford a performance exhaust, FCD, and boost gauge right now, then he should not buy a performance exhaust system.

When I was a broke college student I had only 2 mods on my RX-7: 1) K&N drop-in filter 2) Fumoto oil drain valve. The car remained that way for 9 years until I could afford fancy upgrades. My retarded friends wasted all of their time and money on their cars since they were 16 years old, and now they are still retarded and still broke.

I have the Greddy exhaust on my TII and imo it has a great sound. But from what I understand they stopped making it and its hard to find. I heard RX7store had some but don't quote me on that. But expect to pay somewhere in the range of $900ish.

Do it right, and do it once.

I have the Greddy Power Extreme on my car now it sounds excellent even w/ the stock down pipe. I found an amazing deal on an RB settup (w/ down pipe) so I'm willing to sell the Greeddy for $150 (just needs some tweaking from a muffler shop)...

You don't need a performance exhaust. I have the factory OE exhaust, minus the pre-cat, along with the stock intake. Run 11.5 lbs with a G-Force ecu, FD pump, Hallman remote MBC, and small HKS old style boost gauge. It's been this way since 2001 and no problems.

Evil Aviator

True, you don't need a performance exhaust to raise the boost level, but it will do so more efficiently than a MBC. The downside is that the performance exhaust will raise the boost level whether you like it or not, so supporting modifications such as yours are required to keep the engine from blowing up.
