Smile The rallisport racing prototype....Finally

Some quick photos of the finished prototype is a 4-2-1 technically and the layout flows well! This design was chosen because it makes more sense than other the typical UEL on the market.

1 5/8" primaries and 1 3/4" secondaries, 2 1/4" final diameter. Will bolt directly to the 2.5i cat/mid pipe and retains the stock O2 locations. The material is full S304. Catalytic converters are MagnaFlow ceramic double dipped combs (same as OEM) and all bends are mandrel not stretch. Ports are gasket matched and fit over or past the lower driver side engine mount!






The more juicy info is that a few lucky folks will get the pre-production units ahead of the final production units! This will help ease demand and get these in the hands of owners to test and talk.

Help is on the way

This part made me laugh. How much will I pay for an aftermarket performance part that will possibly provide me with the same amount of power as my stock unit?

Probably about tree fiddy.

Hooray! Any idea of a ballpark estimate of what these will cost when they're in production?

Could be a possibility! 409 is a cheaper option than 304 and it is perfect for Swaintech or JetHot

These are interesting. I'm looking forward to hearing people's impressions and of course, the rumble.

That is the whole purpose to give the 2.5i owner a bolt on solution

Would this gain any performance? Or just the boxer rumble?

I apologize, and I am going to ask the stupid question :: Is this for the older EJ251/D engines, or is this for new newer 2.5i litre engines?

Thank you!

those look nice! I went for the rumble vs the all out 'power' on my RS.. Loved the rumble and it made me happy day in and out. For like 5 whp between the all out best N/A header and the worst UEL ebay replicas.. not talking about much difference in the butt dyno on a DD.

Sound clip please installed..

This. They're going to scavenge poorly and those aren't real collectors. With the old style headers, the stockers were so bad that they'd still be an improvement. With the new style headers, it's a toss up.

Buy them for the sound, not the performance.


Cool lookin though.

Angle on the downstream flange is different.

Thank god they're using a 3-bolt though! 2-bolt flange is one of the stupidest things man ever invented.
