OK guys if you all know me you know that I was going to get the MT true duals. Recently I was sent a PM that said a lot of descuraging things about the exhaust system. I am really having trouble deciding on what to do. I trust you all and would like oppinions on what to do. I need help because it is 1300 dollars I am going to spend here. I already ordered an S-AFC and have a CAI on the way as well. I would like oppinions about the exhaust. Also, if you do not like the setup please tell me why and what you would buy with the 1300 instead of it. I don't want to spend money on the suspension of body right now I have plans for that but right now I want to add some HP to my car. Not including NAWS though, what would you all recommend.

 

TTT

 

True duals sound like **** IMO.

Well, you may not want nitrous... But Id really suggest it. Nitrous express makes very good kits, and rotaries love the juice

 

I know but that seams cheap to me. I don't mind the lawnmower sound I just wanted that power but htis guy on the forum really discuraged me. What else would you suggest?

I am looking a the RX7.com test pipe. and a cheap cat-back. What do you think?

 

If you really want power do what i did.....spend that money on

Bigger Injectors
Walbro Fuel Pump
Street Port
Headers
Prescilencer
Some other goodies.....

Rebuild the engine with the street port and then if you want some places online to buy inexpensive exhausts PM me. You can get an N1 for like 400. Dont forget the clutch and other drivetrain stuff....no matter how much power you have, you need to get it to the ground. If you add NOS to that you might just go as fast as me....

 

$575 for the test pipe and the RP cat-back. Any Idea how many HP this would get me?

There is no reason to port tha biatch it is running fine and killing a lot of rice. But I want more and the MT duals sounded good. I mean 28% increase in rwhp, that is like 30 hp at the rubber, and is permanent not temp like NAWS. Plus any jackass can just throw a system on a friggin civic and beat a lot of faster cars. But when tha bottle runs out so does your fast car.

I don't need any of those things. The stock fuel system can keep up with 250hp and I am nowhere near that level. There is no need in upgrading something on my car which is still opperating within its limits.

 

if you don't care what it sounds like, then just buy what ever brand of exhaust/ mufflers you want. Throw something together: headers, high flow cats, and duramax mufflers or something.

 

Its stupid to mod the fuel setup on a NA, unless you have a huge port it wont be needed.. All you really need is a s-afc and maybe a tii fuel pump. Of course it will be better to have a fully programable computer.

 

I don't care about the sound but I do care about the performance. I don't want to buy some crap system that is cheap but a waist of money.

Can you all post what kind of setups you all have?
And what kind of numbers you get from the setups.

 

drox what are you running on your REX?

 

If you go with the MazdaTrix dual set-up.... it would be nice if you could dyno you car before/after to see how much gain they actually give you... i know there has been some controversy on this topic in the past.

Of course... dyno runs cost money and it wouldnt be ours!

 

If you are looking for quicker qtr mile times put some 4.30 gears in.

 

I wold do it but I don't think this crappy town has a shop with a dyno. I remember that one of my friends new a guy, but I would not trust the numbers unless it is a profesional setup. I could proly get it done at a discount if I make nice with the guy first and then ask him to let me use his dyno. hehe I would like to know what you all have on your cars to see what is available and what has been used and tried out.

I don't do 1/4 mile runs I just street race. I might put in an LSD this spring break but I am not sure yet. I don;t want to mess with my final gears(yet).I appreciate being able to go 150.

 

Why did you even ask for advice? I tell you what GOT POWER on MY FC and you gurus of all that is rotary shoot it down......Do whatever you want with your money....if you think you know what'll get it done then dont ask.....if you want someone to tell you what you want to hear go talk in the mirror.......

I understand that you got pover from what you did but my engine is not ported. On a stock motor you don't need to add fuel because the stock system can handle a lot on a non-turbo. If I had a ported motor then I would do what you did but I dont. Remember I am talking about 1300 dollars. That will not cover what you posted above.

rebuild and port will run me about 2k at least
wlbro and injectors is another couple of hudred dollars not to mention I would have to do a lot of tunning to get the most out of it. I am not putting you down but I don't have 4g's I barely have 1300. Nevertheless, thankyou for your input it is appreciated but I am talking about a stock car not a streetported one. If anyone else would like to share please do so.

 

Im not saying it didnt work with your setup. I am saying bigger injectors on a sub 200rwhp NA rotary is a waste of money. Larger injectors will NOT yield power when you arent even using the stockers to their potential. Infact they will just do an even worse job of atomizing the fuel.

 

It has only cost me 2gs for all of it.....but its cool dude....do whatever you want......it is your money...hopefully someone else can help...

 

Go cheaper go single exit

 

Did you do the rebuild/street port? Or do you have some hook ups that I don't know about. If you could tell me where and how you did it I would listen. If it will give me some good numbers I could hold off on the exhaust and save for a couple of months.

Me no like the look of single exit eshausts. It is like I shoped off the FC's ***** and got it a shinny one on one side.

 

I have (and would recommend) the Racing Beat streetable header and presilencer feeding an HKS 50mm cat-back. It sounds fantastic and will probably match the MT true duals for power. Another good option is all that but substitute the HKS for the Racing Beat dual cat back. find them used on Ebay and you will save a lot of $ I found the HKS cat back at the junk yard for fifty bucks.

 

LOL, u don't care about the sound but the looks area different thing altogether But don't forget that less weight means that you can accelerate faster, and a single exhaust is alot lighter than a dual set up.
