Would there be any adverse affects if I took out my cat and reamed out the substrate, then replaced it? Wyoming doesn't have emission control so I wouldn't have to worry about that, and I'm not moving any time soon.

More power??? hhehehee....... high end mostly. But if you don't have emission at all, just replace it with a straight pipe. You will love it, just be careful, that you might experienced increased exhaust noise.

Is there something wrong with backfiring though? :D It looks cool (fast and the furious come to mind ;))
Not in Wyoming!
I hear EVERYBODY's walkin around strapped :D . Makes sense though, if you got a strap and I gotta strap... it's all good!
Point is, I don't think anybody would jump if they heard it :cool: .

It's illegal to remove any emissions control device even if your state does not test for emissions. I have a downpipe with no cat's on my supra which freed up a lot of HP on that car, but of course I only run that at the track *cough* :p
If you do remove you cat you would be better off replacing it with a stright pipe, because if you just hollow it out the chamber will add a lot of turblance to your exhaust flow and you may actually loose HP.

thanks for the advice! It's funny there have been some that have walked around strapped! It is legal to walk around with an exposed gun! Hey, it's a beautiful place! I'm right next to the Rockies. Good fishing, rock climbing, mtn biking, snow boarding. Plus we have a championship golf course a few miles away. Lot of ******* cowboys and a few ricers, but other than that it's not to bad.

I"m running no cats (3 of them on the Type II) and loving it! I had them build a straight pipe that has a removable section where the cat goes so when it's time for emission test every two years, I slap the cat back in!

And who would ever suspect a Legend ever not to have any cats :rolleyes:

OK so too much backfiring may blow up the muffler over time, but why would a hollow cat ( or a straight pipe) cause backfiring at high rpms:confused: I figure more flow gives a leaner mixture and so less chance of unburnt fuel, no?

How much would it cost to have the pipe made, where would I want to go, and how much horsepower do you guys think that it would add? Thanks you guys, this sounds like something that could be fun, and I don't think that it would be to big of a deal to change it every couple years for the emissions tests. How much louder does it make it though?
