3" Exhaust - Dump Pipe and Cat only
I wanted to throw up an idea that someone put to me to see what you guys think of and if it has good merits
I'm in the process of getting gauges fitted and because I don't have the tools or facilities to do it myself, I am getting a local mechanic to fit both EGT and Boost gauges for me
In order to fit the EGT gauge, we obviously have to get the heat shield off, remove the dump pipe, drill it and weld a boss to it and re-fit it in the car plus remount the heatshield.
Because I'm aiming to upgrade my exhaust within too long but don't really have the $$$ to do it properly at this stage, it seems to me there is a lot of wasted $$$ in this process
The mechanic has suggested to me that if I simply replace the dump pipe and the Cat with a 3" and a high-flow Cat and adapt it to the rest of the exhaust.
That way, I get a dump pipe that already has the EGT bung and if I want to go for a full end-to-end 3" system, I only have to replace the two rear sections.
He quoted me $500 to supply and fit a Redback 3" dump pipe, Highflow Cat and fit the EGT gauge. He also told me that by keeping the original dump pipe, drilling it and welding would probably come to the same price.
He told me he has done this on a few cars already and the reports have been that you actually get the bulk of the benefits of a larger exhaust this way
Are there merits to this approach? Does anyone have first hand experience with a staged exhaust replacement like this?
