*Fits Gen 1 and Gen2/Supra B58*

Introducing the BimmerNetwork B58 downpipe. This is a TRUE 4.5inch all the way until the exhaust meets the dp. This will bolt on to your oem exhaust(no modification needed), or can be cut at the taper and welded to a true custom upgraded exhaust, with the addition of a larger diameter flex joint, this is a real high flowing downpipe that will reduce backpressure and relieve stress off the turbo. Unlike others on the market that are 4.5 at the turbo outlet and taper significantly right after the turbo. **These Are For Decoration Only. Installation On A Motor Vehicle Is Illegal In Most States And BN Does Not Sell For Road Use**
