I've read a little about this subject, but i'm not sure of the right buy.

My mods are intake, downpipe and catback, and i'll buy a power fc + midpipe this winter. But, now i'm not sure if i'm going to buy a resonnated one or not. I know the difference are the sound, but i personnally don't care if it's loud. What are you guys using, and what's the best to use.

I need advices about the sound, and performance, does it make a difference of performance between the regular midpipe or the resonnated?!

Ps : I've searched for those who are going to tell : SEARRCCHHH!

Thanks in advance

None that you'll ever notice. Just get a resonated one, you'll be happier in the end.

resonated. it's just obscenely without one -

Hey Wankel,

Performance wise, it depends on the type of resonnated midpipe you are using. If you are using a straight through design (vs. a baffled design), performance should suffer only marginally compared to a midpipe. A baffled design may hinder the velocity to the point where the midpipe is no longer a true 3.0" midpipe. The major issue with a resonator is the turbulence it causes (thus slowing down velocity of the exhaust gases). The turbulence helps "mellow" out the sound a little. Now how much in real world terms does a resonated midpipe actually hurt the overall performance of your vehicle...probably very little to only slightly.

Is it worth the extra $100 to $150... if you're getting old like me... it's worth the conversation you can have with the person next to you. It's worth not aggravating my neighbors when I drive home late at night. It's worth being able to make an order at a drive through window without turning off my car. It's worth not sounding exactly like a lawn mower....just sort of like a lawn mower .

When I first got my car, I was willing to sacrifice all creature comforts for every ounce of horse power. Nothing wrong with that. If this is your daily driver... I would recommend otherwise. You'll find it very nice to be able to listen to your radio without having to turn it up to MAXIMUM. You'll find it nice to have a cup holder one day. You'll find it nice to actually use A/C. But to each his own. You couldn't have reasoned with me four years ago to go with a resonated midpipe... but now? I wouldn't have it any other way.

I had full exhaust with twins and it honestly didn't seem that loud with an unresonated midpipe. I didn't even notice the change in sound until higher revs. I had Pettit Downpipe, RX-7 Store Midpipe, and GReddy SP catback.

Now with the single the noise might start to get annoying. We shall seee...

thanks a lot for the comments, this is what i wanted to hear. I'm 18 years old. Maybe i'll start with the one without resonnator because i don't really care how loud it will be since it isn't my daily driver.

I'm unfamiliar with Canada road laws, but you should research that. The sound of an FD with a straight through is louder than the 95 decibel limit. I found that the resonated was the way to go without losing my hearing. If it was track only and on an unlimit noise day, then your good, but some tracks also have 99 decibel sound limits for non-race car days so you'll get flagged (again, I don't know what it's like in Canada and don't know your plans for the car).

I'm surprised because the greddy sp has a very loud sound, my dad has this exhaust on his 93 rx7 .. I have a HKS muffler and it's quieter a little bit.

at idle, and low rpms, am i going to make too much noise with the non-resonnated midpipe ? Or if it's only on higher rpms that it will be loud ?
