Back pressure improves torque but at the sacrifise of some horse power.

ask me if i care to see what my mufflers look like under my car? nope as long as they last for a few good years then you can just get the newer improved models. shinny **** under acar dont mean **** on a street car. just like show motors no need to when just about speed, remember this show dont get ya home actually chrome dont get ya home but same concept

all i have on my car is headers and hpipe, when i put on a 2 chamber flow catback, will i lose hp? tq? noticeable that is

Quik

no you will gain some power. one your freeing up the flow in the exhaust. if yoru stock your steping up in diameter which helps. youll gain and love the sound. you may lose very low bottomend but youll make up for it in mid to upper with a good catback. it will be a happy improve ment

nemethjames1

thats just it, i dont have a cat back, so i would think there wouldnt be any backpressure... if it just ends at the hpipe that would allow it esier flow wouldnt it?

bobby

i know, i dont care about shinny mufflers

yes because there is nothing restricting the flow of the exhaust. Backpressure is a kinda confusing subject because to get the perfect performance out of your car and I mean perfect power gains you would have to sit down and really look through your options.

Quik

you need back pressure on a street car and low powerd car. now a high hp car can afford to lose bottem end. they are usually equipped with cams anyways that elimnate low end anyways to make up for topend pull. its a give or take situation. you either have low to mid power with some topend or have no lowend and have mid to upper power. or just plain out topend and nothing else

There's a difference between MagnaPACKS and MagnaFLOWS
and Packs are deeper then 2chamber flows.
Made the switch and was the FIRST thing I noticed.
