Does a stock WS6 catback flow well enough for a h/c car?
Does a stock WS6 catback flow well enough for a h/c car? Say a car with MTI stage 2 5.3L heads (or AS stage 2 5.3L) and a TR224. Or will the stock catback hurt performance? If so, which catback for better performance, GMMG or Magnaflow?
Just trying to plan for the future.
Thanks,
Jim

I know this is very subjective, but is GMMG really loud on a h/c car with headers and cats? I would like an exhaust that sounds tough, but I don't want it to be obnoxious.
After reading the replies in this post it's apparent that I should get a catback. I'm trying to decide between Mangaflow and GMMG. I'm not concerned about price. I'm only concerned with how loud it is and how well it flows. Sorry, I'm sure this is a common question, but if you have any imput it would be appreciated.
Thanks,
Jim

Borla flows very well, even with the full plate on and the exhaust going through the muffler.
For obnoxious moments, you can run open plate. Even better, you can get an electonically controlled butterfly to switch from quiet to loud.

i know someone who is taking this approach with a fully built 383 ci stroker ls1.. he is aware that he is leaving some hp on the table, but he wants somewhat of a sleeper approach, he is just gunna leave hte stock catback for a while then eventually get a better one once everyone figures out what he is packing

Very nice product I might add. Cutouts are good, but you lose time and the cool factor when you need to unbolt the cover, not to mention the plate might be hot and you might not be able to reach it. An electronic cutout fixes all that. You can control it whenever you want from the cockpit. Very James Bondish in a hot rod sort of way.

I'm actually trying to decide between Magnaflow and GMMG. I'm leaning towards GMMG, but I'm concerned that it will be too loud once I get h/c. I don't mind the car being a little loud, I just don't want it to be obnoxious. As for a cutout, I'm sure they work great, but I'd prefer not to use one.
Thanks,
Jim

I have had my GMMG exhaust sinece I bought my WS6 in 2001. Yes it is louder than the stock one but it is not real loud until you get to about 3k then you start to hear the sweet music of the motor. I do not have heads and cam yet but if you are going to change to heads and cam keeping it quiet is going to be real hard. Trust me if you get the GMMG exhaust and you are pushing it people will know.

I have LTs, ORY, and a WS6 muffler. The idle is somewhat louder than you would expect from a stock muffler, but WOT is quiet as greased smoke. Nothing is going to be real loud with cats.
