Exhaust

[bigsteve305]

I want to get an exhaust for my grand marquis. I don't want anything too loud I want it to sound just like the marauder any suggestions on how to make my exhaust sound like that, I want it to have a little growl when I start it want it to be low on idle and to be loud when I step on the gas

[sly]

on these cars... keep some cats on it and put any number of flow through muffler (unbaffled) like magnaflows. I like them on mine. They're a little bit louder than I would have expected on the 93 (but then it's got a PI (03) motor in it). It's not drone-tastic though since I had a shop custom bend the duals into the car.

the 88... in all its' lopo mellow glory.


the 93 as it sits (PI engine)


and the 93 back when it had the original NPI engine of restriction


The exhaust didn't change between NPI and PI. Still stock size duals with magnaflow cats and muffs.

The 88 has stock size duals with magnaflow cats and muffs. In that video it was single exhaust, but it still sounds the same, just a dink louder... seriously... maybe 3 to 6 db louder.

I limit my driving of the 93 because I like the play the radio with my right foot... and I want to keep it longer. The 88 is my DD and rush-hour tank.

Will a H pipe fit on my car this muffle shop told me only a x pipe will. I heard that the h pipes have a lower sound then the x

I have cheapo muffler shop turbo mufflers on mine and they're OK, but if I had it to do over again I'd get the Thrush welded mufflers and pray they didn't get boomy.

X although better flow gives a higher tone more associated with modular motors as opposed to H which gives you a more muscle-y sound you get with a carbed muscle car from the 70s or 80s..

personally id go with an H and a set of thrush turbos, had a nice sound on my 351W

that shop is full of idiots then. I have ONLY H pipes on all of my cars. H pipe actually takes up LESS room than an X pipe.

Just got my exhaust done had an h pipe with flowmasters 40s kept all the cats sounds great to me. Not too loud ill post a video later

When ever I floor the gas a lot of white smoke comes out thru the tail pipes and there's a burning smell. Why is it doing that for?

[bigsteve305]

Clogged cats maybe

no... clogged cat would prevent you from running well as it would reduce exhaust flow to the point of hindering the engine. you could have a coolant gasket leak in the EGR spacer and just be sucking coolant. The spacer can be bypassed by routing the hose from the heater pipe to the spacer to the intake manifold instead of the spacer. then just loop the one from the intake back to the spacer to prevent vacuum leaks. If this is the case, this fix will solve the issue.

Now if the smoke has a blueish tint to it, you're burning oil. Short of replacing valve seals and possibly piston rings, you're not going to stop that. Just keep putting oil in it until you can get the engine fixed/replaced in this case.

Black smoke would indicate running rich, so that's not the problem.

[bigsteve305]

It is black smoke not white. And it doesn't do it all the time only once in a while when I floor it. not low on coolant neither. It's not a whole lot of smoke that comes out. I have a lot of water that drips out too I kno that's condensation but it seems like a lot tho.

I just want to make sure nothing is wrong with the car I just bought rims and in gonna buy tires. Then I'm going to get the self tuner and a CAI so I'm dropping a lot of money on my car I want to make sure There's nothing wrong first before I do all of that. Also just got out the body shop for a touch up . I was gonna get a new mustang 5.0 but it was too much money do I decided to hook up my MGM

[sly]

only when you floor it and black... nothing wrong. the fuel system riches up when you floor it to prevent detonation. You may also have carbon buildup that's coming out when you floor it. Now it is indicating that you've probably got bad burn in the cylinders or way too much fuel (not enough air) so a new air filter and top end tune up (plugs/wires/etc) may be in order.
