thanks for the reply guys,
There is some thinking to put into it.
First, material is not optimal; but better than aluminized steel normally used in car industry for exhaust; which typically last 10ish years. I don’t think I’ll keep the car that long. Nothing wrong with it, love it; but I don’t think I ever had a car that long in my life. 5-8 years maybe. The only thing that could justify to sell it at this point would be tremendous maintenance cost; as I really enjoy the vehicle & look. Not ideal, doesn’t seems like a deal breaker.
Second, with power dream/goal; 2.5in seems quite tight for a 3.0 engine. I mean, I was running a 2.5in on a 1.8 Vtec engine and it was fine. I understand that bigger is not better because of the velocity loss, and turbocharged engine get backpressure from the exhaust manifold/turbo and what comes after that is not a big game changer. 3in seems right…
I am not concern about fitment for the Buzzken.
The rawteck posted above is almost the same price (620 USD VS 560USD) but shorter. 304 SS and 3in. I guess I’ll wait.
Interestingly, rawteck downpipe is cheaper than buzzken.
Bigger is always better with turbocharged applications but there is definitely a cost benefit ratio involved. 2.5" had been in used in 800 and 1000 hp builds. Obviously a bigger DP and exhaust would unleash more power, but it can do an it. 2.5" downpipe had been proven at 500 and 550 hp on the 3.0 tdi also. So, if you CAN do bigger, and it fits and isn't a ton more, do it. Otherwise 2.5" is sufficient.
