American Thuhnder Mufflers?

[MyCARneedsHelp]

i was thinkin about gettin the American Thunder Kit, but rather not use the taip pipes, just a perfromance H-Pipe and mufflers. Does anyone know what chamber these are and where i could get them at? Thanx !

The new American Thunder kits use the Delta Flow 40 series, which are a little quieter and are supposed to have less drone. The old American Thunder kits used the Original 40 series. There's also a Super 40 series, which uses the Delta Flow technology.. not sure what the difference is. Good deals on eBay: Original 40 Series and Super 40 Series

I haven't been able to compare the two from the inside of the car, but from the outside, I like the sound and loudness of the Original series better.

I'd offer to sell you mine if I had another cat-back sitting around, which I dont. My American Thunder droned to begin with, but the O/R X and my other mods made it 10 times worse. I've had mine for about 2 years and I got it at Performance Automotive Warehouse.

Did the O/R X change the RPM range at which your drone occurs at all?

I hear long tube headers eliminate the drone

Nope, the X just made it drone a heck of alot louder in the same 1800-2200rpm range. Longtubes would be nice, but I have the visual part of CA smog checks to worry about.

I wouldn't waste my money on an American Thunder catback if you don't need the tail pipes. Get you a set of MAC pro dumps and save $100. They sound almost the same but the MAC are suppose to be a little louder and without the drone. I switched from the American Thunder kit to the MAC pro dumps and love them. Took me about 10 minutes to put them on in the driveway. The 3 inch Pro dumps come with reducers to work on stock or 2.5 inch h-pipe also.

I think that's what he was asking... where he could get just the mufflers (2-chamber Flowmasters).

i gto a off road h-pipe with 2-chamber flows and 4in tips, much much louder then almost any car in town, somtime i think its to loud, but then i rememebr i like the attention just cruising.

I had the 40 series delta flows and i wasn't very happy with the noise level... wasn't as loud as i hoped. I think i'm going to go with MAC next time.
