Sounds like you put it together with stuff you had lying around. Unfortunatly I don't have any exhaust parts hanging around, I'm going to have to buy it all.
If I do go with the long tube headers and the Pypes system, I'm concerned about having enough room between the headers and the X-pipe to fit the reducers and cats. And before I dump almost $1500 into this exhuaust (670 headers, 250 (125x2) cats, 380 exhaust, etc.), I want to make sure it all fits.
Has anyone done a similar system? Suggestions? Oh...and what is the difference between a Ceramic substrate cat and a Metallic substrate cat?
Thanks
