Description

This 304 stainless steel STM exhaust manifold head flange fits all Mitsubishi 4G63 heads including Evo 1-9, 1G/2G DSM and GVR4 models. The flange is machined with a recessed oval port that accepts 1.5" schedule 10 pipe once it has been shaped and stretched. Doing it this way does take more time and gives you less options for runner routing, but in the end, it makes a better finished product with the smoothest transitions possible.

Fitment

  • 2003-2005 Mitsubishi Lancer Evolution VIII
  • 2006 Mitsubishi Lancer Evolution IX

  • Brand: STM Tuned (made in the USA)
  • Part number: STM-4G63-HFSS

Such great customer service!!

Wow, great company. Fast and to the point. Had what we needed and completed deal in under 5 min and all with good pricing and shipping costs. Had to make a change after the order. Took less than 15 seconds. Great people and company. This was a personal purchase and not for a big company. Just saying.

I've been using LancerShop for all my modifying needs since purchasing my Evolution VIII upon my return from Afghanistan last year. Absolutely amazing communication and they are very quick to get the parts to your door. Each order is documented/archived along with every tracking number, which is great for maintenance records and customer reassurance.

Always great service from Lancershop. Ordered from them many times and shipping is fast. If there is an issue with an order, they do their best to resolve any issues even if it is not their fault! Thanks!

Been shopping with LancerShop for years now. Always great prices and people to work with. Their customer service is always easy to work with and has saved time such as in the last case where somehow the address was missing my condo #. Other places would have sent it out and then the delivery guys would have had to guess. Instead they emailed me and we fixed the issue before there was one. Can't complain about that
