Need Recommendations for Performance Parts/Upgrades
Last year, I purchased a 2004 E55 and am finally getting around to purchasing parts to upgrade the vehicle and make some minor repairs.
I bough a stage 1 package from VRP, upgrading to a 76MM pulley, but I'm struggling to decide what to tackle next.
If I get too deep into the intake system, I'll probably end up spending over $2,000 upgrading the throttle body as well.
At this point, I only want to spend around $1,000 or less on a smaller upgrade...perhaps some mid or long tube headers. However, when I looked at headers, I could only find a few manufacturers in the US and was having a difficult time verifying the quality and performance of the few headers that I could find.
I would get the mid length headers. They have a good track record. If you want HP you have to get rid of the stock exhaust manifolds and the bottle neck they are attached too. 35hp is common at the wheels and you will help with cooling also.
Headers are your best bang for the buck at this point and if you want USA made headers that MBH makes a great set. More like 50 plus HP with your current mods and 20 degrees lower IATs. May be a little higher than you want to spend but USA made and quality is what you seem to be looking for.
Oh yeah, another well kept secret mod is to add a 3000 stall with custom matched pump/stator to your power range. Big time torque mulitplier and makes street driving Super fun!
