View Full Version : Custom Exhaust

09-01-2009, 03:50 PM
Has anyone found a pair of performance headers that can bolt into the stock y pipe with only minor mods like reducers.

Or better yet, has anyone seen a pair of headers + preformance y head pipe that can bolt in on the 5.2 engine without having to make a buncha bends/welds.

I have a question: If you have fat enough pipes to handle the flow of a performance header with a 2 into 1 config is there any difference in performance when compared to a true dual exhaust system?

p.s. I know of the Doug Thorley headers, but i'm just wondering what are the other options.
