im gonna check out jegs too. lol came the other day thru the mail. Oh and i was looking at my pipes, and i noticed a small tube that looks like a mini h pipe. Is that for the smog pump? cuz i ripped mines off and cover the tubing that was left.
 
The tube coming off the stock H- and some aftermarket X- and H-pipes connects to the air injection line from the smog pump at the front. The smog pump has a line off the back of it that branches off in two places - one goes down the the exhaust, the other goes around to the back of the cylinder heads.
 
Be sure that when you get rid of the smog pump and all the hoses you don't forget about the two vacuum switches behind the strut tower and cap off the line coming out of the back of the heads with a heater hose cap/circle clamp. (do the same on the tube coming from your midpipe)

Just an FYI, you do NOT want to cap off the smog tube line going to a factory H-pipe. Those cats aren't designed like the newer X- and H-pipes that don't even have a smog tube fitting, and they'll have a tendency to load up full of crap. On the off-road pipes, though, you can just hammer the end of that smog tube shut with a BFH and a hard surface (I used a big decorative rock in Frankenstang's yard as a hammering surface :D ).
 
SLP sounds like garbage. I've never heard it sound good. Its basically a glass pack. MAC or any chambered muffler I think sounds way better than a flow through (fiberglass packed) muffler. Jus my opinion.

Ehh ... yes and no. A straight-through muffler has the same flow as a glasspack, essentially, but the fact that it has a chamber around it gives it more bass and tone. Also, the amount and type of packing of the muffler will also largely affect the sound. Violators seem to have very little (if any) packing in them, although they're a straight-through design, and they've got a hollow sort of sound like chambered muffs.

SLP's, I will agree, are basically just overpriced and glorified glasspacks, though - they even look like 'em (if it's the same system I'm thinking it is). And besides ... wasn't SLP a GM performance brand, originally? (Mainly for F-Bodies and Impalas.) Maybe the cross-contamination of putting GM parts on a Ford results in crappy sound...? :D
 
DO NOT GET FLOWMASTERS!!! There are much better sounding mufflers out there now a days.

There are 2 mufflers that really sound good on a 5.0.

Pypes "Violators" and "Powersticks" from Classic Chambered Exhaust.


Youtube has several clips of each.
 
SLP's sounded like garbage on GM's too. my Z28 came with them and I swapped them out fast.
damn thing sounded like a UPS truck at idle and when I hit the gas it sounded like a UPS truck that had the exhaust fall off.
 
get u an off road x pipe jegs ones are cheap and 40 series flowmasters your car will sound nice but if u want it real loud slp loud mouths at rpm outlet for $150 a pair they sound tough but there are so many good mufflers just depends on how deep your pockets are
 
I know for a fact that MagnaFlow's H/X-pipes sit up just as high as the factory pipe, no scraping the ground here.:D

I am surprised to hear that. I replaced my complete stock exhaust system about two years ago with FRPP shorties, Magnaflow catted x-pipe and Magnaflow cat-back - and the fit and ground clearance of the x-pipe was just horrible.
I had about two inches clearance (car is lowered about an inch and a half with Eibach pro-kit springs and dampers) which basically made the car useless on anything but highway driving.
Eventually I just couldnt stand it anymore and got out the grinder and welder - which is something you dont want to do with a brand spanking new stainless steel system :mad:.
Magnaflow makes nice mufflers, but thats the only good thing I can say about their products.
