i have not really got good answers. so it is poll time i have a 03 gt and want to know overall what is the best exhaust out of the choices for sound, performance , weight and how easy the kit is to install. Please talk about your gains and experience with these kits.
-HIGH QUALITY Stainless Steel
-Easy installation
-Highest possible gains with this brand (like other brands of similar/same quality)
-When paired with a HIGH FLOW CAT Midpipe this system sounds extremely aggressive. It does not have a low grunt like Flowmasters, rather a higher piched tone that just screams "fast"
Really loud, nascarish sounding = LMIs(imo sound horrible if paired with an o/r pipe, If you stay with a catted pipe it will be 10x better.)
More agressive tone, still pretty loud = LMIIs(my current setup and I love the sound. I have a o/r X pipe also. Still sound real good with catted pipe.
If you want a not so loud sound go with either flowmaster or regular magnaflows.
With SLP, say you got the LMIs, if you don't like the sound you can get either the LM2s or powerflo mufflers and just swap out the mufflers. There all the same size so it makes it real easy.
i prefer SLP but alot of people dont like them, i would pick any on the list just not BLOWMASTERS, I wouldnt get those b/c i am sick of hearing them on every mustang I see
i have magnaflows on my car with a bassani o/r x check my sig for vid, as far as installation goes i really couldn't say cause the catback was already installed when i got the car, the x was pretty simple to put on and i did it completely by myself. Magnaflow tips have a mirrored finish and rest is stainless steel, not a single rust spot yet on the catback
Not one of your choices, but I had mac flowpaths and an o/r prochamber on mine when I had it. Was pretty cheap (I paid about 600 for both new) and although not the highest quality in terms of how long it might last in comparison to the SS ones, I think it will last plenty long enough before you get bored of it considering the price.
Sounded freakin' sweet too! Was pretty loud, but not obnoxious. Very deep sounding like an older musclecar.
Here's a vid if you're interested. Damn I miss that sound.
too quiet and i'd buy the the LM1's, too loud i'd get the powerflo mufflers. the fact that i could actually do all that without a welder was a plus in my book. SLP makes quality stuff as well
ended up with Bassani and wouldn't change it now for anything. set me back around $450 for the Bx catback (aluminized/stainless steel)
