muffler question

[supervisor1886]

True (exept the oil pressure maybe), I am doing some extensive work on the car that is why the rest of the exhaust is not on

Where did you hear that? I know running with just open ports is bad but since when was it bad to run with just headers? Perhaps doing such on a new car would twak out that comp a bit but I dont know about oil pressure and hurting valves!!! If you want to go fast just put a foot of pipe after the collector (long tubes) then you will get maximum power out of the ride. Just prepare for ringing ears and many headaches.

if your worried about the muffler getting stopped up over time then yes it will, a little bit. I bought a used exhaust from someone and I just made a makeshift cap out of rubber and put it on one end of the exhaust and turned it on and got quite a little bit of crud out of it, so if your worried about it then why not give that a shot

your car looks really good
