The RMM DP is a proven performer with excellent fit and finish. A gain of 25-35 RWHP and quicker spooling of your Supra's turbos are the major benefits. Mandrel bends are used and this pipe supports your stock O2 sensors.
I had not one issue with either quality or fitment with this downpipe. Excellent workmanship!!

Standard 3" downpipe. Welds looked fine and it came with a flat gasket for the EGCV housing. Easy to install with basic tools in about 25 minutes (assuming your exhaust nuts aren't welded on). Went from stock boost of .8bar peak to new peak of 1.1bar with a cat-back exhaust (Apexi-N1). Exhaust stinks without cats and need a boost cut controller though. Probably save 10 lbs over the stock downpipe assembly as well :)

Like all of the other downpipes, it performs very well. However, the fact that it is 100% stainless steel is what sold me on it. I do get caught in the rain sometimes, and I was not going to settle for mild steel. Beware of imitations that advertise stainless steel, but the flanges are really made of mild steel. As far as I know, this is one of the only 100% stainless downpipes. No rust/corrosion after 2 years of use. Excellent product.
