KTM and Husky Performance Increases for 50, 500, 501 4-Stroke

NEW! 2023-2024

'GRUNT EXHAUST MANIFOLD'

FOR 250 / 350 4-STROKES

The "Grunt Exhaust Manifold" exhaust manifold has a much better shape than the Large ID stock manifold. It bolts on in munutes and gives you throttle response and pull you can easily feel, from idle to past mid. Works with all headpipes and needs no Fuel tuning. The high temp O-Rings ensure perfect sealing to the head pipe and it's made of stainless steel.

  • Stronger response and pull, right off of idle into mid range, with no loss of top

  • Simple bolt on replacement.

  • Works with stock or aftermarket headers

  • No re mapping required

OVERSIZED TBI EXHAUST VALVE COVER

FOR 2023-2024 TBI KTM/HUSKY/GASGAS BIKES

The easiest ways to add throttle response and bottom to midrange torque to your 23 - 24 250 or 300 TBI bike.  

 

This oversized exhaust valve cover increases the volume of the exhaust head pipe when the exhaust valve is in the closed position.  This works from idle to around 6000 rpm.

​

Easy to install and the gasket is included.  It will give you feeling of the bike running crisper as well, or like you added a high compression head.

POWER BUNDLE

DEALS

I can't tell you how happy I am with the power bundle I bought for my '18 FE250. Delivery was right on time, and it only got better. Love how all the parts for each step are individually wrapped with specific installation instructions. No guessing if this bolt goes in that hole, etc. Your pictures are clear, and the instructions are incredibly well written, concise, and even humorous. Even an idiot like me can understand them! Such a nice change from all the crap that comes from China and instructions that look like they were translated from Mandarin to English using a translator app. But the best part is when I put the bike back together, it kicked over on the first try--no stalling, popping or cracking. But the BEST best part is it runs like a dirt bike is supposed to. SO much more power! You guys clearly know your stuff. Keep up the good work! I will not hesitate to recommend you to anybody that'll listen.
