If you don't want droning avoid HKS (I had it on an N/A).
I've also heard the Apex-i N1 drones as well. No idea on RB.

I have the Greddy SP Sport and it sounds deep and aggressive at idle and wails pretty good at WOT, but doesn't drone at all. That sh*t gets old fast. The rest of the exhaust stuff is in sig.

 

its in my sig, does drone a bit and you have to raise your voice to talk.

 

pacesetter headers down to a cat/racepipe (how saucy i feel), back to an n1 single

Stock and rusty currently...soon to be a custom single cat-back with an Apexi Dunk muffler exiting out the passenger side. :p

What kind of cat is he using?
I was considering doing something similar, I have the RB turbo back and I'm getting close to inspection time. I haven't found any good bent inspection shops, so I need to come up with something that gives me a chance of passing

TIA

 

It was on the car when I got it for him. It's supposedly a Random Technology cat.

 

im running a 3" DP and MP, to an Apex'i 3.75" GT Spec catback.

 

Its in the sign.

 

RB header/pre-silencer

 

Bonez DP
RP cat replacement pipe
Apexi N1 single.

Cheap, light, exceptional sound!

Rb header, silencer
greddy power extreme

listen to it

 

I have the mazdatrix/HKS road race exhaust, dual all the way from the engine to the mufflurs and it is not bad compared to some of the others that I have heard,until you hit WOT,but it will not drone on the freeway.
go to mazdatrix website and they have a sound clip of one.

That N-1 dual is HUGE.

 

What kind of power gains did you get with that exhaust?

 

for the street a 3" racing beat turbo back with the presilencer replaced with a 3"straight pipe. at the track a 3" pipe from the turbo to sticking out by the passanger door.

 

My Racing Beat drowns at around 3K-3500 RPM, I think is because i run gutted cats

 

I have Apex dunk... and it sounds deep and louder than a ****... i'm actually trying to find another pair that isnt that extreme so once in awhile i can hear myself think besides that, i luv it

 

RB 3in turbo back through a 3in high flow cat.

 

I don't have cat back, just a downpipe and a straight pipe. That seems to work better for me and I seem to get a lot of attention, especially by the cops? When someone tells me to turn the base up on my car, I get in and step on my gas pedal. They seem to look at me funny, but hey that's the best that I can do. I've taken out my straight pipe and just ran with my downpipe, but the trebble is too high and not getting the maximum output that I need out of my motor. Anyways, I like everyone exshaust, my question is, is it working for you? Well have fun and Happy Thanksgiving Everyone.


see ya,

on my 91 vert, I just had a muffler shop chop the cats and put in a 2 1/4" straight pipe. Sounds sweet! still running stock header and and stock catback. maybe gained 5-10hp, but in my car that 5-10hp made a huge difference.

happy thanksgiving.
