Well, I pulled the trigger on the new exhaust! Just ordered:

2x 14" magnapacks(2.5")
2X 4X18" Magnaflow tips
1x Magnaflow x pipe

I WAS going to go with 2x high flow cats, but im going to just delete the rear cats alltogether and the front two are as highflow as im going to get from what i have read, and it should be just as loud, if not a little louder without the two rear cats vs. two high flows?

WHat do you all think?! Spent 270 bucks from performancepeddler.com using the code 'clubgp'..

God i cant wait to hear it! prb. going to wait till i get home to get everything installed, still have to find a shop that will weld it all together with SS Mandrel bent piping..

 

hmm I wonder if it would be better to keep stock back 2 cats, just cut them out, or put high flows?

 

our trucks have 4 cats.. the front two are already high flow.. just act as a catalyst, no baffling.. no o2 sensors on the rear 2, so just cut them out..

 

no o2 sensors on rear? I could of swore there was.


well, when you get it in and put everything on id love to hear it! I am ready to get my exhaust done.

 

as far as i know there is not.. Check out darrenws6's vids.. he had a similar setup excet he had magnaflow oval body mufflers instead of the magnapacks.. but it still sounded awesome!

there are tons of guys on here that have done a rear cat delete without any problems

 

I'm pretty sure if you delete the rear cats you have to get MIL eliminators or a tune to turn off the CEL. I'm also pretty sure Darren had a tune through PHP to do just that. (Darren, correct me if I'm wrong.)

Also, congrats on the new setup. Can't wait to hear it.

 

04 and 05 won't set off any alarms...sensor is in front of rears

 

I didn't get tuned until 7 months after rear cat delete job. I never had a CEL. The rear sensors on 04/05s are after pre cat before rear cat. Idiot design. 97/03s were sensor after rear cats, Cali emissions had in rear cat.

 

Good to know guys. Sorry for the shoddy info USA.

 

After much reading, decided on a similar setup. Looking to get it installed this week.
