Custom slp powerflo install on 1.4 turbo

DVN, I agree. If you're happy and the wife is not, swap it for long trips!lol With the bigger Magnalfow muffler I think I might be able to run without a res for a while. I would rather drive my Sierra at 19 mpg of long trips anyway...lol

Do you need to saw off stock exhaust to install or could I unbolt and remove without tampering the stock system. I would like to buy the slp and keep stock just incase I ever need/want to reinstall it. Thanks, Johnopcorn:

You have to cut it. I cut mine right at it turned back to the muffler, right in the middle so that I can either weld it back up if it ever goes back on or throw a flange on it to make it look a little nice when it goes back on. Personally I think they should have had a flange there from the factory.

I am sort of confused why it needs to be cut....btw im installing on hatchback so Im not sure if that would make my install any different than yours...but why cant you just bolt off the stock portions of the exhaust and remove them without cutting any piping?

It is one piece from the cat flange in the front to the tailpipe in the back. The factory installs it as one piece before the rear suspension is installed leaving no need to have a flange to separate the exhaust. I'm pretty sure that the HB is the same way but someone with a HB will be able to tell you for sure.

it needs to be cut, i have a HB

There ya go, all Sonic exhausts are one piece from the cat back and need to be cut unless you want to drop your rear axle.

 

[slitzell]

its a retarded design, i figure that GM did not expect people to change the exhausts on the car.

Because...Economy Car!

 

[rdss]

Agree!

 

[SSonic]

Its worth it though...because racecar!

Its easier to install one piece systems then to have someone go through and clamp them all down ect.

 

[slitzell]

Im sure its cheaper to manufacture as well compared to adding flanges

MOTO strikes again....

I could be wrong with my statement but from working in a production environment this is the best think I can think of

 

[slitzell]

No ur rational makes sense. But i think cost of parts make a diff too.

 

[$ub$onic]

If they save 5 bucks over 90k cars its a big savings

 

[slitzell]

Exactly.
