Do they sell cat delete pipes for TA ls1?

If I got some made up, will I see any hp gains and will my car be much louder? I've got slp cold air and slp exhaust

Just take it to a hole in the wall exhaust shop and have them cut out the CATS and weld in a pipe there's nothing special to buy

Mufflex makes decent stainless ones. I've also run
across some no-name, non-stainless ones that were
alleged to fit but the angles were wrong.

I run the Mufflex tubes and SLP "for stock cats" Y
presently, and don't plan on changing again.

Jimmy did you notice your car much louder? Or perform better? What do I do with my o2 sencers

Honestly probably not worth the trouble. Just buy some LT headers and a y pipe, youll see very noticeable power gains and throttle response will be better too.
If you are not running cats you need to tune the car and have the rear 02's turned off so they wont throw codes.

For stock exhaust manifolds, use DynoMax 88028.

I had a custom setup made that looks just like the pictured setup above^^^

As far as exhaust volume goes, it made it a little bit louder. I have it going into a stock cat back as well. When i got it done i noticed no difference in power. However i put in a cutout right behind the merge, and with a rough street tune with the cutout open i noticed a big difference in sotp feel.

I couldnt afford to do LT's/ORY at the time so i done it as a temporary setup til i could. Paired with a cutout and a tune, id say its worth having. But just the pipes by themselves you probably won't notice anything but extra noise. That was the case for me anyway.

Well if I got test pipes installed in my slp cat back I would also do the tune, so there for would I see more power because of there being no cats

Not necessarily, Stock cats aren't much of a restriction until you start making like over 350HP. It's the stock exhaust manifolds that are the most restriction in the system.

You will pick up some power but not a ton. A tune for it will help and is always a good idea. I've had great luck with the fellars at pcmforless.
