Default 2.5 test pipe with cutout vs. enthuza 2.5 Turbo racer

So im debating between 2 exhaust options. First off, I have a 2.5 inch begi downpipe stock exhaust currently. So i was thinking of getting a 2.5 inch test pipe from enthuza and having one of these welded into it.

https://shop.quicktimeperformance.co...ct_detail&p=24

I like the idea of having a really quiet exhaust stock and then being able to open it up whenever i feel like.

price breakdown:

cutout- $215 + not sure about shipping
test pipe- $50 + shipping
so around $265-290 ish

My other option is the enthuza 2.5 inch turbo racer exhaust. the benefit of this would be that it would be a full 2.5 inch plus wouldnt be nearly as loud as the open cut-out. the only downside is the price and the fact that it wont be as quiet as stock exhaust with closed cut-out

price breakdown:
Exhaust- $378 + actual shipping
test pipe- $50 + shipping
so around $420-450 ish

So for almost $200 in savings, im leaning toward the cutout route. Anyone have any advice or have a preference?

I love my 2.5 Enthuza. What I have is the SS Turbo Racer and a test pipe and it really isn't that loud. This is my dd as well.

How much boost are you running? A 2.5" system will not be too loud for a daily driver. I would be worried about tuning the car with the stock exhaust then being lean or overboosting with the cutout open.

The Turbo racer exhaust is not loud. Its aggressive when accelerating but quiet at cruise. I like it.



This i with a stock cat in place.

im planning under 10 psi. maybe 8 or 9 psi. i think i would have to tune it with the cutout open so when im hard on the car, the cutout will be open anyways and will be properly tuned for it. i could be wrong though
