Exhaust question?

Shamrock

So does anyone know if there are TP's for the Remus? What could the technical/mechanical differences between both CBE's besides sound which exists between any two companies. Both are SS. Both are easily attached. Aren't they just metal pieces?

If the exhausts are CBE, they bolt to stock cat positions. You can get a TP from any company which makes them for the 370Z, and they should fit properly if they are reputable.

You will have to find power numbers for the Akrapovic CBE (which on their website, I believe netted 11 additional horse and 8 torques?). The Remus product, I have found nothing on. There are likely small differences in the cans which may produce different sound. Otherwise, I believe the Akrapovic is a true dual.

I would suggest doing more research before asking; not to be rude, but because in general, TPs are universal fit for any exhaust (all within those made for the 370z) and is a generally known fact.

You will also have to consider what you want in the exhaust, more performance, more sound, perhaps weight savings, etc. or a combination of factors. Since both systems are apparently stainless steel, you will see a marginal improvement in weight, a loss of maybe 10-20 pounds. A titanium system, would of course, save tons of weight given tons of money.

What do you mean by a "true dual?"

edub370

True dual:




not true dual:





true dual is 2 pipes from the headers back. and does not collect into 1 pipe anywhere except where the X or H pipe is

Cool. Where in the first pic is the x and the h pipe? How can a CBE be dual or single? Don't only the TP's determine that. Is the stock dual? This is the Remus CBE

edub370

No thats the akrapovice cat back. so basically all test pipes are is about a 1 foot length of pipe that connect the headers to the cat back. they take the place of the stock cat. after that is the "Y pipe" which is shapped just like the name implies. now some exhaust systems connect to the stock y pipe and some replace it. in the case of that akrapovic, it replaces it. whereas the topspeed catback pictured bellow it bolts onto the factory y pipe.

in the picture of the akro system u can see the "H" pipe connecting the 2 sides of the exhaust between the flex pipes and the resonater. this evens out the exhaust pressures in both sides of the exhaust.

here is an "H" pipe and an "X" pipe beside each other:




as the name implies, one is shape like an "H" and one is shaped like an "X". there is really no advantage to one over the other. they are just different ways to do the same job.
basically if you get test pipes, any system that is a "true dual" will bolt up to it.

What are these second two pics called? I thought the difference between the two types of akropovic (evolution and slip-on) was one had tp's and the other didn't. These basically connect to the stock h-pipe? Is the the stock exhaust system truly dual? This is my friends hks setup.

The second two pics in that post are just the rear muffler/silencer, the very back of the exhaust.

The picture of my friends exhaust setup separates into two mufflers while these are one muffler. Can this still be called a dual system

edub370

yes. even the ones that come into one muffler are still considered true duals. the flow chambers are actually still seperate inside the muffler case. imagine it like the one pictured below, with a big case around it.





i just did a little looking and the difference between akrapovics slip on system and the evolution system is that you will only get the muffler in the slip on, just as u implied above. it will bolt in place of your existing muffler and uses existing mounting points.

the evolution system is from the catalytic converters back. (cat back)

i can't imagine just the slip on changing sound (or performance) that dramatically since u will be using all stock other than the muffler

no systems will come with test pipes from my knowledge. thats something that will have to be purchased seperately.
