I thought I could do it cheaper, I was wrong. The non-glass packed mufflers appropriate for rotaries all seem to be expensive. If you plan on large horsepower levels something else in the 3" or greater range would have to be custom built. That's even more expensive. My opinion only.

I don't doubt the quality or performance, I just don't like the design of the can from an asthetic standpoint, it just looks like a mass-produced stamped generic can.

All SS construction, very similar in performance, sound & quality when compared to the RB catback. After about 12 years on it there is barely any surface rust on any of the pipes, and the muffler cans & tips still look brand new. It is heavy though, but probably just as heavy as the RB or any other dual system.

I had not, but it sounds like another solid choice.

N/A's are probably tougher on exhaust than turbo, so I'd be more concerned about the quality of the downpipe than anything else. Even still, I've heard glasspacks on rotarys both n/a and turbo and they sound like ass, so there's plenty of heat to go around.

Found this advertised on Craigslist as "Greedy Rx7 mufflers" Needless to say I was skeptical...


However, upon arrival I discovered an authentic Greddy Power Extreme Catback with Bonez midpipe for sale for $180!!!

To further sweeten the deal I sold my stock turbo exhaust for $50, and the midpipe (its for n/a) for $80.

I'd stick with duals. I have the Racing Beat RevII turbo back and I love the deep tone it has. It's not obnoxious and raspy but it is not a quiet exhasut at all. Also the quality is very good.

Edit: Somehow I missed the post you made with your Greddy exhaust... facepalm on my part and good job on flipping your stock stuff to lessen the blow. Is any of the piping rusted through?

[Sharingan 19]

Nope, only minor surface rust, a little sand paper, a little high temp engine paint and BAM! The stock downpipe has 2 cats in it and has angles which make it hard to gut. The main cat however got a nice hollowing out.

Replaced the stock turbo (s4) with an s5 unit. Equal sized twin scroll manifold versus unequal collected manifold w/ a switching actuator.

Also suspected the water pump was going bad

Moving right along.... decided to let the ole' girl run free and do what she was designed to do. Went to autocross with my brother (74' chevy nova) and friend (07' honda fit). Since it was my first time competing I was our first time competing we were placed in the novice class along with a C5 corvette, 00' prelude, na miata, crx and some other foolishness. This SR20'd coupe was NOT in the novice class....as a matter of fact it was trailer-ed in and running some pretty sticky tires.




And the results.....


Closest competition was actually the prelude, it had 2 drivers so I'm not sure which one put down the faster time, but it was almost a second back. Fun times.

Was that in Jacksonville this past weekend? If so youre right in my backyard.

[Daedalus704]

Congrats on the results

Actually it was in Brooksville, a little while back. But I've been out to whitehouse before as a spectator (jax is buccaneer region scca btw). I plan to go back once I bake a few upgrades.

Thanks man, it was fun, but it wanted to run hot, so I messed to look into that.

[rxspeed7]

Where are you located? I'm up here in ocala. Lmk of you ever need anything man!!

[Sharingan 19]

Im in Jacksonville most if the time. Im in Tampa fairly often though, with periodic trips to miami and occasional trips to tallahassee.

Actually, I'm looking to put together a hybrid turbo and I'd like to avoid paying shipping costs, so if you know of a turbo shop that can bore out the comp/exhaust housings that might be useful.

[rxspeed7]

Evergreen turbos here in Ocala. Owners name is Charlie brown, he has rebuilt bunches of ht18's for us and does some sick hybrids with em.

[Sharingan 19]

Lol, awesome! I bought a t04b w/ a bad comp wheel for the propose of making a hybrid. I figure I'll have the comp housing bored for a 60-1 wheel and re-use the p- trim turbine wheel in a modified turbine housing. So I might have to drop off the parts next time I come through if the price its right.

How loud is the greddy?

[Sharingan 19]

Actually not that loud at all, granted I still have the stock downpipe and a gutted cat so take that for what its worth. But I still managed to shoot my first ever fireball leaving my friend's neighborhood.

IMO (and many others) the Greddy Power Extreme is the best sounding exhaust for an fc (turbo at least) out there. Yes, even better than racing beat. Its a shame they were so expensive/rare I wish there were more of these systems out there.
