Back Pressure

[Jorgian]

Can someone explain to me the Pros and Cons of Back Pressure? Good or Bad?

[deevergote]

You do not want back pressure. End of story.

I thought Back Pressure=Perfromance... wtf

[deevergote]

Back pressure is nothing but a result of a restriction in the exhaust system. The back pressure itself creates an even greater restriction.

You want flow velocity.

Not enough Back Pressure causes loss of Toque doesnt it?

[deevergote]

:sigh:
No.

A lack of flow velocity causes a drop in power output.

flow. think about shooting a spitball. Shooting a spitball the size of a pea out of a paper towel tube will not go very far very fast. Take that same pea sized spitball and try shooting it through a tiny tube (think coffee stirrer), not going to go very far very fast. Now try shooting a spitball the same size as a drinking straw through said drinking straw. the spitball will shoot far and fast. Just like you want your exhaust to do!

Hows the TasAuto Exhaust sound? I cant decide whether i should buy
2.25 or 2.5. Whenever i do buy an Exhaust im going to cut off the Muffler and weld on a Vibrant Muffler. I like the "stealth" ones. I think im going to go with a "sleeper" look. Stock Intake Box, Black "stock looking" Exhaust and OEM Wheels.

it's loud. doesn't drone too bad if the silencer is in. but it's loud. i swapped it out for a knock-off magnaflow-type muffler from Lou's Custom exhaust. sounds a whole helluva lot better now i also have a 2.5" "tip" (just a piece of stainless pipe) to keep the attention down.

i bought the tasauto catback for the piping and to support one of cb7tuner's sponsors.....

**edit** there isn't much difference from 2.25 and 2.5 piping. either should do you fine.

This is like a generic ebay exhaust and header under 200 shipped i believe. I Figure i could just spray the header with heat enamel and wrap it, i cut the muffler on the exhaust and replace it with a Vibrant muffler. Eh i dont know. 2.5 piping. I dont want any rasp..

[mtnbikaah]

if you still have rasp after installing you could add another resonator

(I really need to get a video/sound clip of my exhaust)
