Impreza_WRX_STi Posted November 6, 2004 Share Posted November 6, 2004 I have definetly searched through and through and many aftermarket downpipes absolutley offer great advantages in power. But I still read so many people's reviews on exhaust leaks. I know, this by chance is due to insufficient work/research upon installation? Problem's are usually flanges! I personally like the Perrin, tho pricey! The biggest reason I like them is the 1/2" thick housing on both sides. I know I could go cheaper, and want to go cheaper, but don't want to have to keep taking exhausts apart due to DP leaks. I understand about good fresh gaskets also! Any last comments on your DP's? What you've experienced good/bad? thanks Max Quote Link to comment Share on other sites More sharing options...
