Hello all,
Wanted to maybe get some input from everyone on this. I am building a TDI Corrado. 98 AHU engine. I am not going for a hypermileage car or SCCA racer but a little doesn't hurt...a good daily driver for a mid forties old guy!
Currently it has a 130 hp BEW intake with EGR delete and 2" boost lines on a stock G60 intercooler. The stock turbo. I am in the process of building the exhaust. The flex line was broke so I replaced it with a 2.5" line. I can either stay with that 2.5" stainless out the back or up it to 3". I haven't decided if I should add a resonator or muffler. Probably run the straight pipe to hear it then if too loud add something to calm it down.
I am wondering if there will be much power increase from the intake to the straight pipe to the different sizes. 3" over 2.5" will not be much extra I would think. How much would a flowmaster kill it? Maybe just a single resonator? How much will mileage be affected?
Any help or comments will be much appreciated!
