If cars like yours typically suffer issues such as backfiring and stalling when using a fixed-ratio atmosphere-venting BOV, the Respons can help. By adjusting the venting bias to suit the car you can achieve a blow-off sound without having to put up with the issues. Like all GFB valves, the Respons utilises GFB's proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100psi+. Put simply, it can hold more boost than any turbo could produce.Installation Instructions

Love everything about it!
Color: Brown
Absolutely love this bag! It’s real
Leather! It’s soft and slouchy. Has MANY inside pockets which like because I carry a little bit of everything. Has plenty of room without being overly huge. I’m using the crossbody strap to keep the weight off my shoulder and my hands free. This is a good handbag…and I am picky! This is the 4th bag (brand) I have gone thru this year alone. I’m gonna stick with this one (brand) til it wears out.

Color: Wine
Very beautiful, I only returned it because I like a much sifter leather, liked the crossbody and the deep burgundy color. Nice and big, how holds a lot. I would recommend this bag

Lightweight
Color: Black
I’m not crazy about the leather but I love how light it is and all the compartments. I got tired of heavy leather shoulder bags and so did my shoulders. It’s perfect for every day and very roomy. I’m using the shorter strap for ease.
I recommend this bag.
