Exhaust silencers/varex exhausts

The only reason you would have a car with e85 only if it was track use and you only ever used e85

I only recently purchased the vehicle, it came with the flex setup but the current tune is e85 only, which is why im wanting to get the tune redone to enable a mixture. 

First i need to get the exhaust redone tho. I was thinking of getting a varex muffler but it sems they dont fit well in the 33 (hang low because of the valve mechanism which sticks out on top) and generally dont sound good.

So that leaves me with redoing the entire exhaust (more resonators and mufflers) so its not a menace when i come and go from home, and then have the aes dump valve somewhere along the line to really open it up. I was thinking of having it before the cat but after seeing how insanely loud it will be (on a vl turbo) im thinking of putting it more towards the rear of the car, after one of the resonators.

They also make them with the motor mounted on the side

Only problem with that is it's obvious to the police, but same same with the aes valve. Most people get the valve precat so it's harder to see when looking under the car from the rear.

So i finally got the exhaust done. Full custom 3.5" stainless with dual tipped sp mufflers & a side exit aes dump valve. 

Not as quiet on the outside as i thought it would be, but heaps quiter inside when driving and no more drone.

How does it sound with the AES open ? Like a full open exhaust or a bit more half and half ?

Im getting the switch and some other stuff wired up next week, so ill post a video then. But ive seen them on r32's and VL's. Depending on where on the exhaust they are placed, after how many resonators etc it pretty much sounds like a straight piped race car. Very loud haha

That's a nice job, looks mint. Keen to hear it on full noise.

Got the car back from having the dump valve wired in and a few other things, as expected its pretty dam loud lol

Did a quick video of Jesse revving it a bit in the workshop, but i need one from doing a cold start inside, then its mental. Obviously very loud when driving with it open, lots of pops and bangs tho

Can you guys tell me a workshop that have installed E85 please and thanks.

 

I know about Tune house and Powerhouse

Surely, just about any shop that has done a Skyline (or Supra, or RX-7, or EVO, or WRX) will have done E85.

But perhaps you need to specify what type of car, what type of engine, what ECU, you propose to be using.
