are you going to have custom tips, or are they simply going to remain like the stock tips that end toward the "chrome" caps?

btw, I changed my opinion on the exhaust for the GS. I need one now lol

We are working on a carbon rear valance to make an exhaust that will have quad tips. That is still a few months away though.

For now we are releasing the exhaust using the stock tips.

Alright everyone

we are finally done with the new LDS exhaust system for the 4GS!!

We put the car on the dyno to lay down some numbers but the car consistently made more power with each run.

We stopped doing running the car after 5 pulls when the car made 10 whp over stock.

The car is now back with the owner for a week to let the car acclimate to all the changes
in a few days we'll re-run the car on the dyno to get some solid results

but for now...heres some eye and ear candy...this thing sounds like a monster!!!! it gets good after 0:30

Exhaust looks/sounds great. I am going to assume this is for a RWD application

I'm so in if you guys make quad tips it would be awesome if the tips are burnt like the TRD. Do you guys know what the diameter is going to be for the tips?
