After comparison in DB aswell as HP/TQ, I think I've found my exhaust. Dynomax seem to be hi on flow, but not so much db or ponies. Magnaflow likes their hp/tq but not db. Flowmasters seem to be too raspy and rust away too quickly and very short on flow. Borla's are just too expensive, Edelbrocks and Hooker are a decent choice, but doesn't have the popularity that the spintech's have. Bank's are nice at idle, but they sound kind of raspy at high rpm's and I couldn't really find any data on them. Bassani is nice hp/tq but WAY too loud. There are others, but don't seem to be as popular as the one's I just mention. So I guess with the highest db-hp-tq/$, I guess it's the spintech's.

On the website, it's super hard to find the 343SC model, that or I'm blind.. so my question is: do they sell the whole kit? cat-back, or only the muffler?

If they only sell the muffler, how can I obtain the 3 inch tubing/mounting required brackets? Thanks for your help.

Oh yea, and where could I find them in Canada? or do they ship out of the states?

 

I think Mufflex makes a kit using the SC Spintech for our cars. Try here http://www.mufflex-performance.com/installation.html

On their website (Spintech) http://www.spintechmufflers.com/spin...ntechindex.asp

go to products/street performance/sportsman split case

all their split case models are there, including the 343SC.
I think they just sell the mufflers, but I would contact Mufflex about buying the whole cat back.
