i just installed an o/r h-pipe and i have flomaster 40 series welded on (on car when i bought it) i was wondering w/my mid pipe if i would get much gains out of a full magna flow catback i already like the sound of the car just wondering if it would give me any gains or if should just spend the money else where

 

leave the flows
by headers instead.

 

spend the money on a computer programer, good way to add like 20hp's. most of them are about 350 to 400.

 

catback really doesnt give you a noticeable diffrence in horsepower at all get some gears or a diablo predator

 

catback is not where the pwr is @ brother.

try some headers

 

 

The cat-back is not where the power is UNLESS you are still running the sh!tty 2.25" factory tail pipes. What would be the point of headers and the O/R midpipe (all 2.5", i'm assuming) if it can't breathe through the slowmasters and crappy tailpipes.

Jeez. Just get some bigger, mandrel bent stuff on there at least. [8D]

 

Try like 10, at most, on a near stock car


Changing out your catback to a straight through design will yeild better exhaust flow and slightly better performance. Seeing as you have weld in flows I would recommend getting a catback system before headers.
