Thats what I thought . Thanks for the info !
You get what you pay for bro. $170 is not bad- better than stock, but.....
Try the new Loudmouth 2 for $350. Stainless and people have been saying some good things about it. Not as raspy and loud as the original. I have the Flowmaster 40 series on my daily driver '94, sounds good, but.... who cares?

i turned my cutout today. i had an exhaust shop do it for $20. it's about 1.5 inches higher than normal. in fact, it's still the lowest point on my car - MAYBE!! and if it is, it's only the lowest by about a quarter of an inch. i'm much, much happier now. 
the only concern i have is that the cutout and i-pipe are both about .5 inches away from the underside of my car. i'm afraid that either one of them is going to flex and dent the floorboard or that the hot exhaust might slowly do damage to the metal underneath? thoughts?

Yea, my exhaust is close to my floorboards. I made sure I had only an index finger of clearance between them, so that ground clearance was not a problem. No banging at all
I also have poly motor mounts, so my exhaust is pretty still.Mine is not that close to the fuel lines though, they are flipped.

in fact, now that i look at it, the i-pipe is pretty much resting against the floorboard in the rear. and if it isn't, the space is very narrow between the pipe and the floorboard. in addition, the the screw on the cutout is about a quarter of an inch away from the floorboard. you think i'm going to see any problems with this?

how many inches does the i-pipe flex under the most extreme conditions? .2 inches or something?

I bought the flowmaster american thunder catback about 2 years ago and it was the worst mistake that I ever made. It popped like everything going down the road and it didn't really sound that good unless I went wot. Thats about the only time I heard the catback. I have since changed my setup to headers/true duals and couldn't be happier. Save your money and get a quality exhaust the first time.
