Flatsix

Hello Rennlist I don't post much but thought I'd share what I did. What is not shown is the BMC drop in filter. The results are very good. I first installed the Tarett UD crank pully I could mostly sense faster RPM and perhaps a tiny butt dyno improvement. I then installed the IPD Plenum/82mm TB. Created good response and much better pull in the 4500- redline. A bit pricey but considering the options are actually limited a worthwhile mod. Then the headers which are some eBay specials. Before you burn me I spent about 4hrs+ on them with my air tools cleaning up the ports and the welds on the inside and inside the collector with my long reach tools. I also matched the factory cat converter flange on the car to the larger header collector. I'm confident the flow is good. Also the tube diameters were the same as the stock pipe size so I believe the exhaust velocity has remained high but with much improved flow. I painted them black to tone down the bling factor. I should also note that I have the stock mufflers with the gundo and fister mod. The end result is really nice the car screams to redline and the additional pull in the upper RPM is impressive compared to how it was before I don't sense any loss in the lower RPM's, actually it's faster. The noise is awesome too. I do plan to get an ECU upgrade to tie all these mods together and I'm looking forward to that actually making everything work even better together.
I purchased the IPD Plenum/TB and filter from Flat6motorsports.com and Jon was a pleasure to work with. I plan to explore my ECU options there as well.
The UD crank pull I picked up from Tarett since I'm local to them.

I must have missed the exhaust video...

Nice. I've been thinking about that UD pulley for my next round of maintenance.
