NEW - TMS - Turbo Management System - Don't throw your BOOST away - INCREASE IT BY 40%! GFB's Turbo Management System (TMS) parts offer multiple performance benefits over factory diverter valves.

Factory diverter valves are commonly known to leak or fail, especially with age or higher boost levels. A GFB TMS will hold as much boost as you can throw at it, 24/7 - No frequent re-builds or replacement required.

  • BETTER RESPONSE Through reduced turbo lag - The GFB TMS is designed specifically to minimize lag - tests show that it can return the engine to peak boost up to 30% faster than a factory diverter when shifting gears, while delivering up to 40% more transitional boost (see GFB brochure)
  • BETTER DRIVEABILITY - Smoother than stock. Factory diverters tend to operate fully open or fully shut. This can cause annoying surging at freeway speeds, requiring constant throttle corrections to hold steady speed. The GFB TMS completely eliminates this problem, making the car smoother to drive.
  • GET THE SOUND - OR NOT - It's your choice! Want noise? GFB patented Respons succeeds where others have failed! By adjusting the venting ratio of atmosphere/recirc, you CAN achieve a sound WITHOUT throwing a CEL, running rich, stalling using more fuel or causing other problems commonly associated with atmo-venting valves.

NEW - RESPONS - TURBO MANAGEMENT SYSTEM FOR 2008-2009 WRX, 2003-2009 LEGACY GT, AND 2009 XT FORESTER. The kit is a direct bolt-on replacement (no modifications or adapters needed) for the factory BOV, and doesn't require any modifications to the car (no cutting of the plastic engine cover!) As with all GFB products, the new RESPONS kit is designed and manufactured to GFB's strict quality standards from the highest grade materials.

2008-2014 Subaru WRX, 2003-2009 Subaru Legacy GT, and 2009-2013 Subaru Forester XT Respons TMS Blow Off Valve by Go Fast Bits

On the surface, it may look like just another dual-port blow-off valve, but the Respons is much more than that. Featuring GFB’s patented venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets.

Twisting the adjusting ring opens up the atmo port, whilst the recirc port is simultaneously closed. This results in possible venting ratios ranging from 100% recirc, right through to 100% atmosphere, and anywhere in between.

When we say “bolt-on”, that’s EXACTLY what we mean. Everything you need is included, it fits directly in the factory location (not on a separate adaptor), and no modifications to the car are required.

Features

  • Adjust the volume of your blow-off sound
  • Get the blow off sound without the hassles - even on sensitive MAF-based systems
  • Hold unlimited boost pressure

Comfortable, Easy to Clean, and Held Up at Coachella
Size: 12, Color: White, Size: 12, Color: White
I’m really happy with this purchase. The shoes are very comfortable, and the product description is accurate. I followed the sizing recommendation based on my foot type and went one size up—they fit perfectly. I bought these for Coachella, and they definitely held up. I was on my feet all day, and they stayed comfortable the entire time. What impressed me most is how easy they were to keep clean. At the end of each day, I was able to wipe them down and maintain their whiteness without much effort. Once I got home, I gave them a deeper clean, and they honestly looked as good as new. Even the laces cleaned up easily. Now I’ve transitioned them into my regular work shoes, and they still look great. Overall, I’m very satisfied with this purchase and would definitely recommend them.

Great shoes that are well made, lite weight, and comfortable.
Size: 12, Color: Brown
Just received my 2nd pair of shoes from Bruno Marc in a size 12. These are really lite and comfortable. It can be dressed down to be a casual shoe or dressed up with a nice suit. These run true to size so I ordered my usual size 12 and the fit was perfect. Being my 2nd pair of Bruno Marc's, I like the quality of their shoes and each shoe is described appropriately on fit and comfort. Insole of these shoes were awesome and provided soft comfort on the feet along with a slight arch support too. Will definitely consider ordering more Bruno Marc shoes in the future.

Cushioned, comfortable, stylish and a rubber sole!
Size: 10, Color: Brown
These shoes check multiple boxes for me, comfortable, cushioned, rubber sole and stylish. As my feet grow old and worn out, I'm on a constant search for comfortable, cushioned shoes that are suitable for work and dressier occasions. I have tried many expensive shoes that look great but either lack cushioning, arch support and or comfort. One of the nice things is these shoes have a rubber sole, where most cushioned shoes have the foam soles which are great, but they tend to lack grip particularly when its damp/wet. They have average arch support, but the insole is removable and I put my own cushioned arch support. Love these!

OG Style
I am a big fan of Bruno Marc shoes. Over the years they have provided comfortable and affordable boots and shoes. These blue, tan and white soled dress sneakers are no exception. They have a nice finished look that makes them both causal and dressy. The lightweight style is still warm enough for colder mid-west winters. The box of the toes is wide and comfortable. The insole is well padded and a pleasure to wear. This is another fine pair of shoes to add to my collection and yours.
