anyone have these?
As the title says I an wondering if anyone has these. http://store.summitracing.com/partde...5&autoview=sku
I have doug's long tubes and I am gonna build a duel exhaust. I want someting like the gmmg (stainless works) mufflers but I have to use my credit at summit so I found these. Any input would be great.

Re: anyone have these?
I have those on another car, the 3"in-out version. They are pretty loud but give a nice deep rumble (3" true dual stainless exhaust, full length headers on a souped up 360 SBM).

Nice twin_turbo! Do you think they sound close to the gmmg's or classic idustries chambered mufflers?

Re: anyone have these?
I have no idea, I have never tried those. The magnaflows sound better than the dynomax race bullets in 3" though, the magnaflows have a deeper sound to them.
I'll be using some european mufflers on my 87 iroc since I can get them locally and they're only 50 euros a pop (the magnaflows are more when you figure shipping and taxes) also they have them in 70mm, about 2-3/4" no one in the US seems to have that size and it's my preferred dual exh. size.
Borlas sound very nice too, these are old corvette stainless borla w/ intercooler tips on a 2.75" true dual exhaust w/ 3" high flow stainless cat cons.
It's this system, I would ssupect a similar sound from regular borla stainless mufflers in that size.

Hey Twin_Turbo
Are those little bullet cats up by the collectors? Who makes them, are they possibly available in the US? Did you make the shields?
Nice system, I'll be it runs!!

Re: anyone have these?
Yes, they are 3" in out high flow cat cons. They're made by powersprint here. it's a German brnd and they are about 450$ a pop, not cheap at all but the only high flowing ones reaily available here. They come with the shields:
