Why do some after market exhaust (specifically MS Sport, which I have) make popping sounds when shifting gears at high (7K +) rpms

Raptor75

For the same reason that they are louder. They do not muffle the sound as well. The MS I had let all sorts of pop come through but with the RB you hear none.

There are some pops with RB, definitely louder than stock (in stock, all you hear is interruption of exhaust sound for a split second), but they are more muffled pops, there is no high-pitched component to it... still sounds sweet!

It is mostly because of the stock tune and there is less back pressure than stock.

When I installed the Canzoomer and kicked it up to stage 2 the pops lessened considerably.

Canzoomer works well? Also, would resetting the ECU allow it to realize the less back pressure and adjust the intake/fuel mix etc.?

You can reset the ECU, but it will go back to where it is now, as far as the popping.

Unless you have a CZ or other fuel management to smooth it out.

The CZ changes timing some as well.

I use to hear alot about CZ about two years ago, but now all I hear about is the Interceptor X. How do they compare? Or don't they?

MS vs Corksport? Are they really the same or are people just grouping them because the design is the same? Any MS dual can vids? I'm between this and the HKS Hi-Power - wish I had the dough for the Ti Jic.

savedsol

2 things, are saying your JIC is louder than the RB racing or regular RB? Second if you sell the JIC - let me know

The Corksport and MS are similar in sound and design. Corksport may be a bit louder but it may depend on the car.

I have corksport on my car. It sounds very nice with stock cat. You can hear the wail when driving on high way and it encourage you to rev and rev because it sounds so nice up the rpm range. You won't hear the rotary sound...the exhaust sound drown out all the rotary sound that you use to hear with the stock exhaust. But if you put a midpipe on your car....it still sound nice but it will be very loud, especially from 2-3200 rpm range and then again from 4000 rpm upward. I recently got pulled over because of it. I was doing 70 mph on the express way...around 3500 rpm or so and the cop said the exhaust was too loud. You definitely feel different in acceleration in the higher rpm with the midpipe. The tip on this exhaust looks nice. Some may like it and some may not. Over all it is a good exhaust, not to mension that it only weight like 29 lbs.

I know this thread is about RB and MS....but....let me throw another in the mix for value, quality, and sound. I installed the RX7Store's exhaust - see the link when I got my '8' in the summer of 05. It is a stainless exhaust using Magnaflow cans (polished) with a 3 inch pipe and polished 3.5 inch tips.
As of now, the tips have not yellowed and the sound is perfect for my liking....louder than RB but just a bit quieter than Greddy or Borla without any 'rice'. Nice and deep under normal driving and very agressive when you get on it. It does 'drone' just a bit at highway/constant speeds but I think most aftermarket systems will.

Hm.. Nice read.. I've been leaning towards the MS but ain't sure.
btw, as anyone bought the MS sport exhaust? Is there a difference between the sport & the dual?

savedsol

I have the sport on my car. Very quiet except when you get on it - but even then it's just smooth like a quieter F355. I've neverr heard the others but am considering selling it to replace with something "else".

salituro64

Looks and sound. The sport exhaust is the dual can version. I think it looks and sounds great.

RotaryP7

Hm.. Aren't they both duel?

Ah, ones single and the other is duel. I'm guessing duel sounds better..
Weird though, cause they're about $100 in price difference.. Single costing more..

savedsol

Most reviews say the dual is way (as in WAY) louder (look at the tiny mufflers) and very droney too between 2500-3500 RPMs. Some people have sold theirs for this reason, just read this thread. They are both stainless.

#1. Mazdaspeed Sport Dual Muffler Exhaust - Part number from Rosenthal Arlington Mazda.(RX08MS1025) Is this the one with louder sound?

Price $579.95


#2. Compared to Greddy SP2 vs Mazdaspeed, which one has louder and deeper sound?

salituro64

I have the Mazdaspeed Sport Dual Muffler Exhaust and it sounds great. It's loud when you open her up. Search for the sound bites, but I think the Greddy may be louder.

thank you this was exactly what i needed to decide!

Well it has been 2 years now so I figure it is time to update my review. The Race Beat has been great. I use Old English on the tips and they look good as new after 2 Chicago Winters.

The Sound has gotten a little deeper but seeing that I drive the car daily is would be difficult for me to notice the difference after 2 years. Once the exhaust gets hot it is a little louder which in my opinion is nice. The RB is very easy to live with but you never get the roar of some louder systems. On the other hand my sons friends say my car sounds like a race car.

Over all I'm still happy with the system and love the looks over the stock system. I see stock pipe now and just think how bad they look. 3.5 to 4 inch tips really make this car.

If your looking for a little louder system with great looks, easy installation that will add great looks to your car you can't go wrong with the Race Beat. If your looking for a really aggressive much louder sound, you will be disappointed with this system.

Enjoy.

I had a need to review this old thread so I thought I would update it.

5 Years now and the system is holding up great no real rust and the tips still looking new. I use the Old English polish on them about once every 2 months and it cleans them right up. The sound is getting a little louder with age and I find this nice. I can hear a little pop from the exhaust now and then. As stated before, the system is louder when warm but still very livable, no drone. Over all pretty happy with the investment and if I ever sell the car I bet I'll recoup most of my investment in the system by selling it separately. Over all a good investment in my eyes from a look, sound and financial recoup stand point.
