Better than Magnaflow?

[10R]

After reserching the current Magnaflow cat back for th 06 Civic coupe, I personally found it to be a waste of money. Please do not take offense anyone who already purchased it, it does sound great, but its a lot of money for what you get imo. The piping is the exact same diameter as the stock system, and the stock system is stainless so why change it. There is no high flow cat with the system and they replace the resonator with a slightly better flowing one.

Anyway, what I did instead was just cut the resonater and stock muffler out completely. I put the Pro-Flo Twister exhaust on and just put a chrome tip on it to run out the back. The twister is an extremely high flow exhaust, and sounds great. The resonator is gone, so no restrictions there. Matched up with my Fujita intake, I noticed a really good gain throughout the powerband. Until they come out with a high flow cat and headers for our EX coupes, I personally think this is as good as it gets in the air flow department.

I bought all of this and had it installed for only 200 bucks, in comparison to the 461 and up for the Magnaflow cat back. Rainbow muffler sold it and did the work. They recommended this over the Magnaflow system, and they are an authorized Magnaflow dealer. I've seen nothing but good reviews on the Twister, and I am extremely pleased with the sound and performance. When I get a way to post up a sound clip for you guys I will. It is very comparible to the SI Magnaflow sound clip. Anyway, I just wanted to give you guys another avenue to think about and research for yourself. I'll post up pics and a sound clip as soon as possible. I promise anyone who chooses this route will not be dissappointed!

After all that, no pics.......?


Shame on you.......

[10R]

LOL!!! Sorry! I'm not trying to tease anyone, and I apologize for such a long post. I just thought pics would be useless without a sound clip, so as soon as I can borrow a video recorder from my buddy at work I'll get it all posted up.

Which twister? 18" or 23" overall? Sounds like a very decent alternative.

hmm... Wish I read this a month ago...

with the magnaflow you are paying for a bolt on kit that has been dyno tested. I would rather install a complete kit than hack up my stock exhaust. Thats just my opinion

[Yodums]

I'm just waiting patiently for other companies to come out with exhausts. I'm in no rush at the present moment since I have other fees to come such as tuition! $3000 for one semester.

the catback is better than a hacked stock exhaust. Not only is it mandrel bent but it is researched,developed,flow tested, and dyno proven. Not to mention it will last longer than the car......since it is 100% stanless steel. So by the time your stock exhuast starts falling apart and corroding, your muffler and reosnator were a waste of money. Thencyou would have to hack those off and put them on a new exhuast, that's alot of money ......all while the magnaflow would still be nice and shiney. The stainless cat-back is a great invesment, my $.02

I don't get where everyone is getting this idea of a "hacked up system." The piping on the Magnaflow is the same in diameter as the stock exhaust as I mentioned before, and its stainless so I still don't see the big advantage. Do you think a Magnaflow dealer is going to undersell himself when I've got the cash to do either system, how would that have benefited him? That is why I go there because the guy can be trusted and he's honest about what the best thing to do is, whether it makes him more money or not. If you think the Twister is some junk rice can you can buy all day on Ebay for 25 bucks, then you need to investigate it a little more. The WRX guys are all over it and its more strait through than the Magnaflow. I'm sorry I don't have a dyno report for the exhaust, but there was definately a very noticable gain from what I ended up doing. I'm not the only one who thinks so, as all my friends who rode in it stock can tell the differance as well. Also, as I said before, the resonator was removed, so I don't think I'm ever going to have to replace it in the future as you said I would have to as its already gone. You guys can think what you want, its your money to spend, and I hope your happy with whatever purchase you make. I was not cutting on what anybody else had done, and I'm not trying to bash Magnaflow, they make a quality system. I just wanted to offer up another quality option, that I am completely satisfied with, until headers and a high flow cat come out anyway. I'd appreciate it if a bunch of people didn't start flaming on the idea just because its differant than what most are doing. Why is it so hard to keep an open mind? I'll get the pics and sound clip posted this weekend, and if people still want to knock it, then so be it. Last time I checked it was my car, and I was just trying to help out with some new ideas, nobody else has to do it.

i just talked to my exhaust/mechanic regarding a catback
and he told me not to bother on this car, he says that
the intake and exhaust is making it flow very well and i wont
see any gains in a catback. He mentioned trying to see if
anyone makes a throttlebody spacer which would do more
even if its only a few ponies.

[skittleslegend]

I think all of you are forgetting that he put it on an R18 equipped vehicle, not the Si. There's plenty of room for performance in the R18 so whether it was dyno-tested and researched or not, he's going to post some decent gains. He's not ADDING horsepower, he's freeing what was already there. Anything that flows better than stock is guaranteed to provide some kind of gain.


Btw, 10R, I was totally just messing with you on the pic thing. lol

I think we've got a buyer!

10R, I like the sound of what you did. Let's see some pics and sound clips if you don't mind. :)

I don't know who your mechanic is, but nothing could be farther from the truth. Almost anything performance wise on any stock car can be made better. I noticed gains when I put my intake on, and I've noticed further gains with the exhaust mod. The stock exhaust is restricted, however minimal it may be. The more you can unrestrict it, pulling more air in and pushing it out faster, the more power you will gain, as well as fuel efficiency.

Alright guys, here ya go. I think it sounds better in person, but it gives you guys a clearer image of what I did and how it turned out.

Thanks for the videos, but no I don't think that it's any better than the MagnaFlow muffler.

I agree, it doesn't sound better. The Mag cat back sounds great! Getting almost the same effect for less than half the cost is what makes it better to me. The power gain with the Mag would be no more I assure you.

Speaking of dyno proven..... anybody seen Magnaflow dyno results for the 06 Si? I was all over their site and could not find anything for the 06 Si. One would think they would post the results seeing as they have two dyno's in house and use them for development of all systems. Guys, I would not be so quick to the draw in discarding this alternative. Being that the diameter of the stock pipe matches that of the Magnaflow where is the improvement going to be made? In flow improvement through the resonator and muffler. Twister is a quality muffler and well known in performance crowds.

Thanks! Thats all I've really been trying to say.

10R - I will give you props for your choice here. Others may not agree, but thats ok.....discussion is key to knowledge and everyone's opinon aids in the process.

I was ready to pull the trigger last night on the Magnaflow when I saw the other thread with Hotexhaust shipping it for $361. My better half was ribbing me on how I was always saying it was better to wait for the dust to settle on performance mods. We engaged in debate for a few mins and her points were valid. Why wouldnt they be, same one's I used more than once in conversation. When I thought about it some more I realized that one of the main reasons I had not put a Greddy or DC exhaust on it yet were due to the fact that their designs had not really improved that greatly over the stock design. Their small gains were only realized through better flow from basically the axle back. For the money they wanted it didnt really seem worth it. 100 bucks a pony is pretty far out there.

So in the end, I shall wait a bit more. I like the idea of just improving flow by changing the muffler. Makes for more economic sense and brings the bucks to pony ratio back in line.
