I am looking at 4" exhaust systems trying to deside on one. thinking about getting the silverline or the Hog performance system. both systems are T304 stainless . any advise ?

 

Not familiar with those two, but RIP ROOK has some nice systems, really cheap prices, I personally do not like the stainless system for the fact that they are more prone to cracking, I prefer aluminized steel. Just my 2 cents

 

RPM Outlet has an aluminized 14gauge not 16 gauge like the rest of the companies have for $288.00.

mojave_ron,

Both will bolt on and work for you, however you're in CA and 304 might be over kill for that part of the USA! You can get a 409 system from us for about 30% less and still be upgrading to a better material than stock, or go with an aluminized for even less and it will last a long time in CA. Plus all of ours are made in N.A., so you're keeping your money here in the good ole USA a lot more than off shore products! Call us if you have any questions etc.
