[Umpas01LTNG]

OK, pics will be up soon, but.... heres my problem, i was goin to go with either a Flowmaster or Magnaflow Cat-Back, but my friend, bought me two Moroso Glasspack/Mufflers for my 21st, which is next Tues. btw so i had them installed becuase i mean lets face it, it would be bad if i told him no, so they were installed. They dont sound bad a t all, but are a lil too loud, but im sure they wil grow on me, but i cant tell if theres any gains, or losses, or if there is a decent amount of back pressure, so that is why im charging my battery to take pics, but while its charging lemme explain the setup, its true duals 3 inch(no cats) to the glasspacks, which they clamped out. so lemme know what you guys think, i think i might be losin some back-pressure, the thing is so loud i cant even hear the blower, please guys any help would be appreciated, thanks in advance

In your first post you mentioned backpressure twice, like you want to KEEP Some. The mufflers are PAST the Cats, and a Glasspack will have little effect on adding ANY pressure to the exhaust - Consider it almost a straightpipe if it is a Cherry Bomb type of Glasspack.
Then, you mention High Flow Cats. Any Backpressure you HAD will be released by these if they are any good.

So, I'm confused. Do you WANT a little backpressure in your exhaust? You are Supercharged, NOT Turbocharged.

Second. If you had a Mustang question - this would be a good place to ask. However, Yours is a Lightning question and would probably be answered best by Lightning folks. Try NLOC.net too.

i want to keep a decent amount of backpressure, that is my goal, you see i bought the car with straight pipes that were welded to a stock muffler, and it sounded like garbage, so i told my buddy i wanted a new exhaust and he bought me glasspacks, so i was like fine and put them on, what i was sayin about the Highflow cats is that i think i should throw two on, and i think that'll solve my problem with the backpressure and the loudness, lol, i just wanted some second opinions, becuase as much as i know about cars, there are plenty of people on here that know a lot more than me, thnaks for the replys tho guys

By My Count I get 127 Mustangs
17 "Other"
11 Lightnings

Over 11.5:1 Mustangs over Lightnings. We show more "Other" vehicles than Lightnings. If our great braintrust of 11 Whole Lightnings doesn't have the answer, What's a fella to Do?

Push the Lightnings Out? NEVER. I'm One Too.

Haha yeah... Mostly the Cobras. Oh well, anyone that owns an SVT is family to me. :headbang:

Back pressure. You wouldn't loose back pressure if you had no c/b.

IMHO i wouldnt bother buying high flo cats youll end up blowin em out with the truck anyway and there not gonna do much for the sound

Just one question. Did you look inside the glasspacks before you put them on? I had a set of glasspacks several years ago that were for a 2.5" exhaust, but after looking inside them the core shrank down to about 1 3/4 inch. If I would of bolted these on I would of enden up losing power as the rpms got higher.

i cant remember the size of the inside, but they are big, 4 inch for sure around, and def bigger than 2 inside, but they are too loud and poppy, im just gonna throw on either a 50 series, two 40 series, and then just save for a bassani
