Would you drink a milkshake through one of those little coffee stir-style straws you get at the gas station or church? Of course not! You want a straw that's going to deliver that chocolate goodness in a hurry and without a lot of effort. So why are you still forcing your turbo to use a small flat downpipe in your LB7? It wants to move air and be efficient, but that crushed looking pipe isn't letting it breathe easy. PPE has the solution with their Stainless Downpipe for the 01-04 LB7 Duramax. Crafted from 304 Stainless for longevity and reliability and formed with a clean lined flange to a smooth proper round tube for more efficient airflow. Let your turbo breathe easier, and keep your under-hood temperatures down, as the PPE unit is also wrapped in a titanium woven thread for superior heat protection for your other components.And in this case, our friends from California can benefit too, as there is a California specific Downpipe for you all too.
Please make sure you select the option noting if your vehicle was originally built as a California specific vehicle, which would include an EGR system, or a Federal (non-California) vehicle.

Better value & quality
I was using the Paula’s brand but stopped ordering because the price kept going up. This came up in my search and it’s almost the same except it has a stronger concentration & has a few more added benefits. It’s also about half the price. This product works great & I’ve been using TruSkin Vit. C moisturizer for years now so I knew their other products work for me and are good quality.

It works for my Very sensitive skin
This is the most gentle liquid exfoliant I've ever used. I have very sensitive skin and 3xs a week doesn't bother my skin at all!
I Highly recommend it.

Bye bye ingrowns and dark spots
I love this exfoliant, I've bought it 3 times already. I use it on all my hyperpigmentation on my back, underarms, and face. It really helps with my ingrown hairs and reduces the appearance of dark spots. Super effective, I love it!

Great product!
I use this once a week. I apply with my fingertips. (It is liquid, so a little goes a long way) After you wash your face for the night- wait a few minutes then apply this. If you don’t wait it might sting for a few minutes- so wait.. Apply your moisturizer after. My face was so soft the next day after one use. It is now a regular in my skin care routine. I do not use another active like retinol or tea tree serum the day after.. just moisturizer. Would recommend and will buy again.

Good product
This seems to be working really well. I used to use a different brand of BHA and I like this one better.
I do wish they had an eye dropper version, but it’s fine.
