Switched Divorced to H-pipe Flowmaster 40's

i-bought-a-v6 · October 22nd, 2010, 01:56 PM

Well a couple of months ago I got dual flowmaster 40's h-pipe but it turned out it was divorced. So I went back to meineke and they put a midpipe in right after the cats. My car now feels slower but sound is much more consistent and the I can actually hear the deep sound at 700RPMs at a red light. Also there are no more vibrations

.
I got this done an hour ago so maybe it will feel faster tomorrow but if anyone has any input it will be appreciated.

its a little more backpressure man...so it'll feel a bit slower, however if you gut or remove your cats that'll fix you right up

i-bought-a-v6 · October 22nd, 2010, 02:00 PM

Its too late for that now but is there any other way I can fix this and if I can't will I get better MPG because of the lower RPMS

i-bought-a-v6 · October 22nd, 2010, 02:04 PM

Should I just push the pedal harder and then achieve the same effect withought the loss in MPG

The more you push the pedal the more gas you use, if you're going for power (generally speaking) you get worse MPG
and it probably isnt that much slower...

just curious, why did you got from divorced to an h-pipe

an h-pipe will make your exhaust tone deeper

i-bought-a-v6 · October 22nd, 2010, 02:12 PM

Yeah and it was free so I thought why not. and it definitely is deeper but not as loud.

thats why you gut your cats

i-bought-a-v6 · October 22nd, 2010, 02:23 PM

That wouldn't have been free and they said no anyway

i-bought-a-v6 · October 22nd, 2010, 02:24 PM

But does anybody know if this will affect MPG?

v6kid · October 22nd, 2010, 02:54 PM

There shouldn't have been any noticeable difference in power.. I'm assuming that it won't have an effect on mpg (at least a very small one).

mustangmike! · October 22nd, 2010, 02:57 PM

i have an x pipe, its deep as hell lol

I just didn't want to take the chance that it would be raspy. Also is it possible that the loss in power is because they didn't make big enough holes in the pipe when they put the midpipe in because it looked like the diameter of the pipe was 1/2 an inch bigger than the holes?

i-bought-a-v6 · October 22nd, 2010, 03:11 PM

I am getting pics now

JTs03v6 · October 22nd, 2010, 03:26 PM

At the very least your car will run 12.89 at 114.3mph

Would like to see the work though

I worked out a deal for new twin precision turbos that will run a 5 PSI each. With professional installation of custom fabbed piping for a total of 5K.
