Exhaust: MAC 5.0 GT Catback with 2.5" Durablack Tips! Made with 2.5" diameter piping and using MAC's "True-fit" technology.

H-Pipes: MAC Performance Dura Black Coated 2.5” High Flow Catted H-Pipes. These mid-pipes feature super high flow catalytic converters.

Headers: BBK Equal Length Headers. standard 14-gauge mandrel-bent tubing with 3/8" flanged ends, precision die-stamped and laser-cut flanges, and screw-in studs. Each of these headers are 1 5/8 in. These equal-length shorty headers and will create an additional 8 to 20 HP.

What do u guys think?

 

I would just keep it all unless you want a different sound. Then I would either change your H-pipe or your mufflers. Otherwise if it isn't rotted or anything I would keep it.

 

Im wanting a nice loud, deep sound. thats why the H-Pipes and Mac Exhaust. i think im choosing the right stuff. Also the Headers should be a nice touch exspcially for the + HP

 

i personally dont like interior sound so id say dont get mac, plus ive heard of problems w/ their kits fitting correctly.

 

what the question? should you change it and if so what to change?

 

Long tube with 1 3/4 primaries. 2.5" collector. Magnaflow 2.5 off-road X-pipe. 1 chamber flowmasters 2.5" in/2.5" out dumped. This is just for the freeflowing loud **** exhaust plan.

 

I thought a MAC H Pipe wouldnt bolt up to BBK headers?

 

i would get long tube headers, off road x pipe, and a slp catback, this setup sounds wicked!!

 

Sounds loud lol .... VERRRRRRRRRY loud.

 

if your looking for a few more hp's then pull your old headers and clean up the welds in the inside of the headers which can be around 2-3 hp's you'll seeweld buggers and such
