Need some thoughts on exhaust....headers have 3" collector and I've come down to 2.5" with a reducer cone. Was going to run 2.5 throughout with a turbo muffler ( Cherry Bomb or Dynomax) to tips in rear valance and a 'H' pipe . Was in a muffler shop to get estimate to do it and he suggested 2" tail pipes to maintain back pressure ? and then they would fit the 'stock' exhaust tips I have since they are 2" also . this would save me modifying the tips to open them to 2.5". I believe stock pipes were 2" from the mainfold. Suggestions? anybody using a Cherry Bomb turbo.....how's the sound?.....thx......
"Backpressure", it means restricting the exhaust flood, yes?
I must confess to know very little about the benefits of backpressure.
Can anyone tell me what good this backpressure does, and why there's a lot of hotrods, gassers, dragsters, and so on, who happily races nearly without an exhaust system, and does'nt seem to mind the lack of backpressure?
When muffler producers such as just Cherry Bomb makes mufflers which they claim will reduce the backpressure, my confusion is complete.
