I've been looking around for cat backs for awhile now and I've grown fond of the Borla and Agency power. But what i was really wondering is out of all the aftermarket exhaust setups available for the rx8 which is the lightest?

 

HKS Hi-Power
Race Roots Single

and soon to be

Corksport Single

 

Not even close...
Revo tune or custom single exit. The HKS is pretty heavy for being a single exit catback

 

I think I am "pretty close".

Any single exhaust readily available is going to be the lightest unless you go full titanium. I am assuming the OP is asking because he has done no research, and has no idea which is the lightest.

Which to me means, chances are he isn't going to buy something that needs imported from Japan, and he isn't going to buy a full Ti exhaust.

I also forgot about the racing beat race exhaust--which again is a single exit.

 

You're right in reading the OP but still... the lightest aftermarket setup is a single exit, titanium one! Had he asked about buying it from the states only i'd agree with you.

 

this should be titled "What is the forum Search Engine?" the other question has been asked and answered infinitely already

 

Agreed, can't argue that.

 

straightpipe titanium bosozoku style

 

jic-magic titanium single is pretty light.

 

invert your header, and to straight threw the hood.

 

that is a universal picture and they never made a single RX8 exhaust, you could buy a Ti muffler if it is still in stock as they have quit making exhaust systems in general and anything left over is on clearance

Ti is not necessarily the lightest, it depends on the thickness vs the material, but again this has all been discussed before even though all the usual bad information still gets spread about

 

Team, you are completely right.

but wahkupup has the ultimate idea!

 

QTP Cutout added into "Already Good" exhaust system. Again my 2 cents

 

I have the racing beat single exit race exhaust pipe, pretty sure they don't sell it anymore, but it sounds awesome and its 34% lighter than stock.

 

^ Is it a keeper

 

I have the lightest ! Trust titanium . the damn thing just cracked and i'm having a big job finding someone who can weld it such that I don't have to take out a mortgage on the house just to fix the damn thing....

 

That's why I use light gauge T321 stainless instead .... and no it's not the lightest
