Contour Enthusiasts Group Archives Forums Modifications Duratec Performance New Exhaust questions??

Ok, I am going to go with true duals. I want to know if my design would be good or if I should try to copy some elses.

Here's what I was thinking:

Cut the stock y pipe and make two pipes out of it. Then bolt this high flow cat: Dual IN/Dual OUT Cat
Then finish the job with dual mandrel bent piping to the mufflers in basicly the same position as the stock ones.

One question though; will I want resonators?
Will replacing the stock mufflers be a good idea and what mufflers should I replace them with?

Also I was going to get the mandrel bends from jcwhitney. Anyone found a better place?

I don't know if my variations will translate - I have done 2in/2out mufflers, but not a cat. I have been unhappy with a 2in/2out arrangement. Largely for noise, but I believe low end and mid range performance has suffered as well. No proof though. I suspect there would be a better way, but you won't know if you don't try.

If you must preserve a cat, perhaps try 2 separate smaller ones and do not cross lines.

This is a new one for the CEG. Anyone else got any thoughts?

its seems everyone is taking the initiative to do there own true dual set up . You think yo-dude could have put something together by now ... caugh groupbuy cough

I read the posts for the groupbuy and honestly I can't see paying $700 for duals.

I found the piping from jcwhitney for under $100 (for the mandrel bends that are needed for duals).

So basiclly that dual in/ dual out cat sucks? Are there better brands of cats? Do I just need to make sure its super flow cats?

I found high flow cats on ebay for $50. Are these ok?
Bomz Cats
or these?
Car Sound High Flow

Summit sells good cats for a good price.
