tsp headers

[Fast6.3]

Can I run no cats for a few days while I can get a tune to turn of the rear o2 sensors?
I know that they are just for the cats and my cel will come on but it wont go into limp mode right?

Sorry didnt give all the info I will be installing tsp 2" long tubes no cats this weekend and getting tuned during the week

I want to run catless long tubes with Borla S type axle back. Anyone know if it'll be throaty or raspy?

Just do it this is one of those things that once you do it you'll always be happy with.

I am under the impression that catless is more raspy than same set up with cats.

Just an FYI - the TSP longtubes with the off-road extensions won't even have a bung for your rear O2 sensors. I removed mine and made a plug from the GM OEM connectors and some silicone.

Make sure you purchase the 02 Sensors extensions from TSP.

TSP 304 headers are not heavy, the 409 version was heavier, but we went to standard tubing for the 304 version to get back to equal weight.

Mine dont either and I got them last month

I just looked in shipping & the 1 7/8" has a spike, but the current version of the 2" does not. I can added it if you guys would like in the future, but my testing data was exactly as we've been shipping so I don't know currently how the spike will effect power output. I will get a test set built with spikes to see if it changes anything.

I'll keep ya posted

What did the spike add on the 1 7/8 headers?

Rich I'll look on my 5th gen data. On the 4th gen headers is made no noticeable change in power, but it looks cool :P

Do you guys want me to see about adding a rear o2 sensor in the cat pipe? The o2 won't stop the ses lights from the cats though. We use high flow cats that still trip the SES light.

I'm subscribed Jason so will you post those results here or start a new one?

Thanks
