Which exhaust housing .63 or .85? PT70

My combo is in my sig. I am just wondering which housing would be better the car is mainly street driven going to the track maybe twice a year. I've had both housings on but for a very short time the .63 seemed way faster because I was constantly baking the tires. The .83 people spooled way sower but this helped traction. People said this has more top end but at what speed is it really noticed. My tune was better for the .63 than the .85. Just have the turbo off and want to get peoples opinions before I put it back on.

For the 1 to 1.5 mph you will pick up with the big housing you loose the fun off the light, not worth it going big on the street, in my opinion.

X2. Just my honest opinion. You will be alot happier with the .63 housing for a street driven car.
