Hey people,

Just wondering what exhaust gives the best gains for an 88 N/A FC. The car is stock at the moment but i don't want to buy a system twice so i want to buy the appropriate one now. 3 key future mods will be:
Large street port
56mm ITB
Microtech
Cork Sport headers
De-Cat pipe

Veiws on best perfomance cat back, idea of diameter? Would like to stick with twin exits like stock but would consider singles

cheers

 

I would go with a full racing beat system, i have it on my fb and my buddy has the dual outlet one on his fc. They really make great stuff.

 

something straight thru is good, 50-60mm.

you're also going to want to put a muffler in the center, its going to be loud without

 

SDJ header, borla XR-1 and you flavor of a muffler at the end, magnaflow sounds pretty good.

 

haha SDJ header?? i wish i could find one, AWR racing makes a nice one as well

 

rb true dual?

 

I love my Racing Beat

 

i love the apexi set up... i would have to say in my opinion it looks and sounds the best hands down

 

I have the single 3" apexi on mine and I love the sound

 

question

for dual exhausts from brand name dealers like Apexi or HKS

would you buy the universal 2.5" muffler and weld it to the existing pipe because I don't find any application for rx7's

if so, I am interested in getting the HKS Hi-Power muffler found at

Apexi GT Spec Hands Down the best sounding exhaust on FCs

corksport is too flashy, too big, and too loud.........i am looking to replace mine.

 

would like question answered please

 

Racing beat is nice for a setup that is bolt up and gives a nice tone and a decent power gain, but this was for the best exhaust for an NA FC, and the best just isnt an RB system. Even with my SDJ and free flowing back half it is still lacking but I cannot free it up anymore due to amount of noise created.

 

no... you would just buy the complete exhaust from corksport, mazdatrix, andysautosports, or other websites that carry that brand exhaust

 

Has anyone Bought a Greddy Evo2 Exhaust System For They're FC ?

 

true duals give great power and noise

 

i mustve misunderstood this question a apologize... you cant find HKS exhaust for hardly and NA anymore, but you can find the Hipower exhaust for the TII some places. so yes, you could do it that way if you wanted to

 

I absolutely love mine, it's a little loud with the RB header and presilencer and the bridgeport, but when I put it on with the street port, it sounded awesome. Amazingly enough, though, if you want it quieted down, the silencer that goes in the tip of the muffler really quiets it down without limiting power too much on a decent tune (engine struggles past 8k with it in, without it spins happily to 9200). IMHO, if you run this exhaust on a stock 13b n/a, it's just way too big and you'll lose power, but if it's at least a large street port, it is a great system for the price. The only thing I don't like about it, though, is that it exits on the drivers side, not passenger for better weight balance (and the dB meter at the track is on drivers left)

 

Yea man I had it on my Old jump off S4 with weber 48DCOE cleaned up ports. Racing Beat Headers test pipe n I loved it. But tryin to get another on for my S5. & I would like it to exit on the pass side but it doesnt still sexy tho.

I have the RB true dual and I used some header wrap from the header to the pre-silencer. I have to stick my head out the window to hear it. It is very quiet with it wrapped.

I have a stock header, and 2.5 inch pipe going into a cat at the Y pipe and some big a$s mufflers.

I'm getting an RB header.... one day

 

get the RB dual setup. its a bit on the pricy side but you will know where your money went. its relatively quiet for cruising, however when you start to get on the throttle there is a noticeable difference. you wont be dissapointed.

 

yup...
Racing Beat or MazdaTrix true dual would prolly be your best bet.
Thats what is on my list of "to do's"...

 

a header and 3" system with my mid pie will give you the highest gains and when run with a big ultra flow, borla or magnaflow will test in the 97-98db range with a turndown tail pipe.scca e-production big street port ported factory 91 intake my exhaust stock t-body 225-230 whp
