I have a 93 JGC 4.0L. About 6 or 7 yrs ago my exhaust manifold developed a crack in one of the welds. After doing some research I chose to install Borla headers instead of a stock manifold. A few years later my catalytic needed replacing. I chose to go with a high flow version to complement my Borla headers.
Finally I think its time to replace my stock muffler and tail pipe. I have been waiting for the muffler to pack it in but it just wont. I have almost 350,000kms but the muffler wont quit. I cant wait any longer I am itching to install a cat back system.
I have been really happy with my Borla headers. In my opinion Borla products are first rate. So naturally when it came to shopping for cat back systems I visited Borla first. I have no doubt about their workmanship and overall quality. I was dead set on getting the Borla Cat Back when I came across another manufacturer...Dynomax.
According to the Dynomax website their stainless steel cat back system out flows Borla by a fair margin. Here is a link to the graph http://www.dynomax.com/ultrafloss.stm
The Dynomax Ultra Flo SS is 100% stainless steel and comes with a lifetime warranty.
I have done a search on this forum for Dynomax. Most members here have made positive comments regarding Dynomax's cheaper Turbo model.
The Ultra Flo SS is substantially more expensive. I want to go with a premium quality cat back to complement the rest of my exhaust system.
Im looking for member feedback as to which way I should go. Borla, Dynomax or some other brand?
