MikeROD16 · May 8, 2008

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.

Darkwriter77 · May 8, 2008

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.

MikeROD16 · May 9, 2008

ohh ok, i want to get rid of the complete smog smog pump system when ii change the exhaust and heads.

and lasersvt, i noticed your lurkin around a few threads lmao

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)

MikeROD16 · May 9, 2008

ok thanks a bunch!

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.

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 ).

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...?

85Vertible · May 9, 2008

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.

DucatiRdr · May 9, 2008

Anyone with FHE with the Edelbrock cat back? How does it fit/look/sound/flow?

stykthyn · May 9, 2008

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.

MuDDuQ · Nov 25, 2008

Im thinking of getting these 2 items if anyone has time to look and has any advice is this all that is required for my complete exhaust system on an 1990 Gt vert AOD 5.0 if I remove all the smog junk. Should I go with the H or the X pipe?
PYPES SFM10V - PYPES Violator Exhaust Systems - JEGS
Flowtech 53605 - Mustang X-Pipes - JEGS

We installed Violators on my sisters car, stock motor, catted midpipe and violators in a flowmaster catback...

Car is quiet and doesn't sound great at all... very disappointing.

dr59l · Nov 25, 2008

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

Really do you think thats the Catted midpipe making it quiet? Im afraid to put it back on my car because it will tone down the exhaust alot i think?

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 .
Magnaflow makes nice mufflers, but thats the only good thing I can say about their products.
