so how dose that sound compare to just having the stock system minus the muffler bc thats what i have and im looking to get a new sys (of course) but i love the sound i have and want something close to what i have now

 

Yeah, I was waiting for that other video to load, and as soon as it did, I was like, well crap. Time to edit that post, haha.

That may be what I do. How much of a pain is it to do? I already have to swap brakes after the track days.

That's just ridiculously incredible. Reminds me, my friend's Saturn, you literally could hear it from over a 1/4 mi away. It was awesome getting next to anyone talking on the phone, or just anyone you wanted to **** off, and you could drag the brakes to give it a bit more throttle, and all of a sudden they couldn't hear their phone conversation anymore. Alright, that's the douchebag in me coming out.

But for real, were some of those passes WOT, like the first one, and when you turned the camera the other way, was that WOT when you took off?

In this video:

 

^^ that's Francesco's car, it sounds Awsome in person

 

I don't doubt it one bit.



Same set up?

Man, just one more month.

 

Nope, it was this:

Racing Beat Street Ported Templates
Racing Beat Header
Racing Beat Dual Resonated Mid Pipe
HKS Hi-Power Cat back
MazdaSpeed Flywheel

 

Ah, so the only difference in exhaust between that video and the other street ported video was the mid pipe?

 

i happen to have a hks hipower and a racing beat resonated decat on during this run.


Ive subsequently changed it for a racing beat rev4 as it was too droning on the motorway............................

 

14.9 = Weak

 

What are you running boosted?

Also Thats probably why Im going MS3 in May! LOL

 

Bump!

Does the HKS Catback bolt straight up to the stock exhaust, otherwise?

 

100% straight bolt on.

 

Works for me then. Should be ordering it in the next few days.

 

I just installed mine a couple weeks ago and I love it. A lot. I left my cat on, and I can't imagine how loud it would be without it. Most people tell me it sounds like a huge crotch rocket when I get on it at higher RPM. It has a great bellow at low RPM as well. But at the same time, I can cruise at 3-4K and it's nice and quiet. It really just depends on if your feeding it gas or not.

Installation is a snap. I swapped it out in my garage, alone, in about two hours. The worst part was getting the hangers off, and even that wasn't bad.

 

looks pretty good man

 

I was hoping SOMEONE would put it on with a stock cat!! Do you have videos or cruising vs WOT?

Does it have just a muffler in the rear, or does it also have a resonator in the mid pipe section between the cat and muffler?

Do you guys think a silencer can be installed in the tail pipe for street use?

 

I have the HKS hi power on mine with the stock cat and header. You can hear some clips of it in this video. Yes there is only 1 muffler on it in the rear section. The way it is designed it would be very hard to add a silencer in the tip. If you wan to order one let us know, we can get you a great deal on one!


Here is another video from outside. This is when the car only had the Cat-back and that was it.

 

I got the HKS hi-power installed. It does drone a bit from 2500-3000 rpms (~50-60mph), but 65mph+ it quiets down. overall volume with stock header and cat is very reasonable. I feel it's the perfect volume for track/autocross, and it's livable for everyday use (I am sound sensitive and I find it mostly pleasant). it has nice burbles on deceleration and loud pops during some 9,000 rpm shifts at the track. fitment was great, and it's light and looks nice. perfect for an enthusiast prioritizing performance and track use.
