I'm looking for an exhaust and since the availabilty of 2.5" systems seems pretty limited, I think I'm going to use a 60mm instead. I tried searching and looking on the web, but haven't been able to find the specs for any of the major exhausts. Which ones are a full 60mm or more wihthout necking down at some point in the piping or muffler?

 

If you want a custom 2.5" ... IM SMSP

 

The JDM Mugen Twin Loop is 60mm while the USDM Mugen is a mere 2.25". I can't seem to win. If I get the JDM one my b-pipe is longer and the Carsound cat wouldn't work and if I use the USD> one it's not big enough in diameter.

 

Buy the JDM Mugen exhaust and JDM-sized Carsound cat...you should be able to sell the cat you have now to make up for it.

 

Thanks. I didn't know carsound made a JDM spec'd cat.

 

Why 60mm?

Everybody makes a 60mm exhaust: Greddy, Hks, apexi, etc...

If you are actually doing any performance mods for your car, just get 70mm or 2.5"... Otherwise, what are you buying? A kazoo?

 

whats the benefits of a 2.5 (70mm) on an R thats stock? with intake and headers?

 

I'll buy your cat, if you sell it at a good price.

It's for a JDM 2.5 to a USDM 2.25 right?

Then don't, but talk to Mike at IPS Racing (TypeRmsm) and he will hook you up with what you need. Just tell him which header and which exhaust you are running and you'll get an appropriately modified Carsound that fits your application.

 

Whats SMSP's IM or e-mail?

 

it really benefits like JUN cams(love to breathe)...i believe their exhausts are 2.5" inside piping all the way through, and go under the rear axle to the muffler(less air restriction)

 

SMSP wants over 300 for the b-pipe.
I recently got a brand new RSR exhaust for 317!

 

nope..usdm and jdm are both 2.25 inlets...the only dif. is the length of b-pipes

 

Does anyone have an exact price on the Kakimoto R? Also since it is a JDM spec exhaust, I assume I would no longer be able to switch between my stock manifold and cat and a JDM header and cat/testpipe due to the difference in length. Finally, is there the typical "bottle-neck" at the connection to the cat or is it a full 70mm throughout?

 

It will cost as much as Spoon if not more. I know the B-pipe is over $350.
Some exhaust have bottle necks like Tanabe, but the exhaust RSR doesn't.
