Ok i know the whole story with using the search engine on the website and i have been looking for someone to ask a similar question but i can not find it.
I currectly have a custome dual exhaust set up after the last cat on my 05 RCSB Step Side Sierra. I would like to know what i would have to do to add LT's would i have to redo the entire exhaust? I would really like to avoid doing this but just wondering.
Thanks in Advance

 

when you say after the "last cat" what are you talking about? We have two cats, one on each side and they are places in the exact location as the other but on each side of the ypipe.

If you wanting to run TRUE DUALS then you could probably get everything to work with minimal changes to your exhaust

The route most take is just buy the Off Road Ypipe that deletes the cats.

 

he basically cut the 2 in 1 y off the stocker and put duels from there... your going to need to redo your y pipe

 

allright thanks guys
i met the 2 cats i dont know wat i was thinking when i typed that
should i also buy some 02 sims then? and where from ? ebay?

 

You can cut the cats out of your OEM Y Pipe and then keep your existing set-up if you'd like. I welded myself up a cat-less Y Pipe and installed my LT headers with it. It works fine as flint!

Also...don't fool with the O2 Simms......just contact NelsonPerformance or one of our other Tuning Sponsors and get a tune for it.

 

thanks you guys helped a lot ill be ordering them sometime this week the LTs the ORY and then the nelson tune to congratulate myself for another year of school off the record only 2 semesters left
