PHR 4.0" Stainless Exhaust for 1998-2005 GS300

Powerhouse Racing is proud to introduce the newest exhaust system on the market for the 1998-2005 Lexus GS300. Unlike others on the market, this exhaust features your choice of 4" diameter piping from the cat-back.

 The PHR 4"  Exhaust comes standard with a V-band flange designed for use with a midpipe. Add our 3" 2-bolt adapter for perfect pairing with a OEM style flange.

 The rear muffler section chosen for this system was none other than Burns Stainless, known throughout the industry for making the highest quality exhaust components! Piping is constructed of 304 stainless tubing then hand TIG welded in house here at PHR by our master welder. The entire package is finished off with a mirror-polished 5" tip.

 This exhaust is a perfect match for anyone currently making or planning to make over 800 rwhp. With an 18 year track record of making only the highest quality products, you can be sure that this PHR exhaust system will not disappoint!
