Beuller? Beuller??

 

Really man?

you need to do some research on MotorDyne exhaust...

 

I have the Borla exhaust on my sedan and like it, the only thing i did not like was it was not loud enough for me but once adding Labree resonated test pipes i fell in love.

 

Stillen was determined (years ago) to not yield as good of gains as several others (on dyno) - this is for coupe.

Sedan is a whole other story... your suggestion of Stillen vs Motordyne (on a sedan) is very likely... I don't think there's necessarily a "better" choice than Stillen for sedan.

 

You may be right. However I dont believe that there is much gain to be had on an aftermarket catback exhaust at all for the G coupe DE.

 

If you go straight through with a system, it'll harvest gains, the MD will show gains, even on the G. However, the cats and y-pipe are the biggest gains to be had, i will say that having driven with those replaced, and just now replaced the rest of the system with the MD Shockwave, that it does feel freer and easier flowing whilst driving, it just wants to rev.

 

Here are the only choices:

If you got the money to spend
Motordyne TDX2+ART

If you don't got money to spend
ART+stocks exhaust

search and you will find many independent dyno's for the MotorDyne exhaust

 

I have a better idea of what to get now. Its either MotorDyne with or without ART Pipes, HKS,or TopSpeed (its cheap).

 

One of the cars we have we have a Boral Exhaust on it. It isnt that loud but it does not give you headaches either. Its the stock exhaust sound with the volume of the engine turned up to sound like a little sporty.

 

Yeah, Borla usually make nice systems, but on the 350 it *is* quiet, just not as quiet as the stock.

I have ART pipes and the Shockwave with the HFC modules, it sounds great, it's quiet at idle, it's quiet (very nearly same as stock) when cruising, makes all the right noises below 4k rpm and sounds almost like a Ferrari after 4k.

You can easily get the Shockwave and upgrade to ART later if you want.

Topspeed is cheap, but the sound isn't as sophisticated.

 

I've never heard motordyne in person but it sounds pretty bad in videos IMO. A few F.I. and HKS videos on youtube sound much better to me. I'm assuming they sound totally different in person.

 

I'm trying to get a video edited of the Shockwave, i used a proper stereo mic, so it should come across much better than most vids of it. However, i will say that it does sound fairly different in person.

 

So I just installed my Motordyne Shockwave TDX V2 myself today.

The exhaust is absolutely amazing. You hear all these good reviews about it and once you have the exhaust installed. Then you will know why there are so much good reviews.

The exhaust has a pure sound with no rasp at all (I have ART pipes as well)

It rumbles and sounds deep at low RPMs (1-3k) after 3k, it just sounds different even at WOT.

I came from a NISMO S-tune catback exhaust, and I got rid of it bc of the lack of power I was getting, the rasp at certain RPMs, and the drone it gave me cruising at 60-70 mph.

Once I had the TDX V2 installed, the only drone I get is when Im climbing up the gears and cruise at 40 which is something I hate.

Even thought the V2 claims no drone, it has it when cruising at low RPMs. But once you get around 2.8k the drone disappears.

As for performance, I drove hard doing a few runs with my stock exhaust and honestly, I felt more torque with the stock exhaust but it seemed to climb the RPM slower.

With the TDX, it didnt seem like the TQ was there anymore, but it climbed the RPMs faster!

The sound is soooo pure. I love it.

 

Put some miles on it, it changes the drone. However, you shouldn't have any drone upon acceleration unless you are making it pull at low low revs.

No drone on cruise, no rasp anywhere. Make sure you removed the evap canister guard, per the instructions.
Again, let the exhaust run in, a good thousand miles, you should have no drone when cruising, even at low rpm.

As for the tq, you can only tell that on a dyno really, but you'll feel like it's trying to pull harder with the quieter stock system, but you already noticed the increase in speed after fitting the TDX2. Get a tune, mine felt quicker just daily driving after the TDX2 and even more so after the Uprev.
