Alright I bet you've heard this 9898435 times but I ask. What exhaust has the deepest tone? Meaning not rice. My friend put a Greddy on his WRX and Ive never heard a 4 cylinder turbo sound so good. BTW I will probably add a MP too so please take it into consideration. Finally there are only 2 RX7's that Ive run into in Miami and they both have HKS and seems a bit ricey for me.

Thank You for any comments.

from what i hear the rb dual has a nice tone.

I've also heard Borla setups can be decent as well.

Anyone got a MP with an Apexi N1 Duul? I like the Apexi cause its bigger than the Racing Beat one. I bet they flow the same but I like the look. Any tips. BTW I went to that link before this post. But over 80% of the sound links are gone or not working. =/

I ahve an N1 dual with a resonated MP. I jsut switched from a blitz Nurspec to the N1 dual. The Nurspec had a deeper tone when it was on my car.

Just spend some time reading other people's posts re: exhaust sound.

Honestly, everyone will tell you to just get the Racing Beat or PFS exhaust. They are quieter than most others and have a nice low tone but scream when the secondary kicks in.

All of the cannister exhausts sound about the same, there's just different levels of loudness.

The midpipe + dual N1 is about the loudest exhaust combo possible (GT exhaust would be even worse). It will basically sound like a chainsaw on crack...

When they say "exhaust system" is that just the TIP or what else?

blueskaterboy

n1s are the loudest **** ever. sounds pretty cool but it is really loud even when "silenced". if you like loud:

but when they say exhaust "system" what does that mean? or include? just the tip or more?

rynberg

An "exhaust" pretty much means cat-back exhaust.

cat-back = muffler, pipe to muffler from cat

When people say they have "full exhaust", that typically means they have a downpipe, midpipe, and cat-back exhaust.

Fatman0203

Aye thanks, was just curious. So n1 is loud huh =/
I heard the Tanabe on my friends WRX and it sounded pretty good. Man so many choices LoL

This is a bit off-topic:

I had a chance to compare my HKS cat-back to a RB Dual. Iwa ssuprised to find that my car was actually quieter.

I have an Old school HKS oval shaped exhaust with a DP & HF cat and it's pretty quiet compared to the RB Dual w/ a DP & HF Cat. My car is Non-Seq too.

Zerobanger, is running an HKS Turbo cat-back w/ a MP and his sounds even quieter than my car w/ a HF cat...

Ive had a Racing Beat single in mine and even though it sounded deep it was very quiet. I now have a PFS and it still has that deep note and its a little louder. I like it a lot more than the RB

I have a mp with N1. Had Blitz nurspec on order for like a month and gave up. I kinda wish I had waited b/c I like the deeper sound but being able to drown out sound systems on cars next to you can be fun sometimes . It might not be so loud w/ the stock twins tho..?

In response to what you said about your friends wrx, it does get a nice tone... and you would be led to think its because he picked a good exhaust right?

WRONG, thats only half the battle... The wrx has a flat 4 cylinder which is almost incapable of putting out a ricey sound...

the more you know

ok, question, since we're on the topic here. Im trying to decide between the HKS carbon TI and the Apex'i N1. What do you guys think, taking into account everything from sound quality and appearance (exit angle of muffler, finish, etc...) to Performance and durability. Hearing from people with experience with either of these systems and what they think would be great.

nobody ever mentions the m2 dual in these posts. it's a great exhaust with a deep throaty tone.

You just did

XSTransAm

i dont know anything about the hks... but if i were you I would listen to sound clips and look at pics... make the decision on which YOU think looks better on YOUR car.

Honestly as far as performance goes, the difference at most is gonna be like 2 horsepower. Can you feel 2 horsepower? i know i cant Besides, thats why god made boost controllers, right?

Most canister based exhausts have the same type of sound or tone, but in differetn decibel levels (loudness).

When I played around with different mufflers (N1 single can, Borla, Greddy dual cans, RE Amemiya) for my cars, I thought the Borla (I recall getting the XR1 and making the rest of the exhaust piping) sounded great if you like more bass in the exhaust note.
Next to Borla as far as bass like tones, I like Greddy's old dual canister exhaust for the FC.
The worst tone is the Apexi IMHO. I don't even like my RE Amemiya exhaust and it's 3.75" piped. It's obnoxious and a bit on the raspy side. Wait... actually the worst is the dynomax muffler. It is way more raspy than my N1 and RE exhaust.

Just a word of caution, it's hard to base the exhaust note on your car if you reference the WRX. The 4-boinger boxster engine is definitely unique and different from the rotary.

The coolest thing about a rotary is that it's the closest sound to a motorcycle exhaust note when you're running high rpm in a car.

XSTransAm,
The difference in horsepower is going to be more than 2 horsepower when upgrading the stock exhaust (cat-back or full) to an aftermarket performance exhaust (i.e. HKS, Greddy, Apexi, RE, Borla, etc). You won't feel 2 hp or much of any hp since torque is what you "feel" and hp is what keeps you accelerating. Exhaust should free up back-pressure and provide a better stream for the exhaust pulses (imagine the exhaust pulses are like sound waves resonating through the exhaust pipes and mufflers).
As a byproduct of a free flowing exhaust, you'll spool a bit faster and with a stock turbo (internal wastegates) you'll probably see more boost creep.

How about the Tanabe?? Anyone heard anything about them?

XSTransAm

I think you misunderstood what i said... I am in complete agreement that you will see more than two horsepower from stock to a upgraded catback... However between the different catbacks, ie hks, apexi their will not be a big devience.

Yeah, I wasn't sure what you meant by your statement so I made sure I put in "compared to stock" comment.

I agree that there will be minute differences between the aftermarket exhausts given the same piping diameter.

Why is the Blitz exhaust so cheap compared to all the rest?
i've heard nothing but good things about it so why is it nearly 100$ cheaper than all the other canister style exhausts?
