very very very loud but am wondering if i need to put a x pipe or something in it i have been hearing about loosing back pressure or what not somebody help me out(darren) on what i need to stick back there.


ill try and get a video sometime later on.

 

An X pipe would be a pretty good choice. It wont kill all of your sound, only a small margin of it, it will due away with all low end rasp ( you'll still have it in WOT and high rpm ) and you will still shake the pavement with loudness, just with a properly balanced system. Since the left bank is longer and needs to be guided over to the passenger side ( original Y pipe ) its longer, and not as strong as the passenger bank is, the X pipe levels that flow out and is healthy for low end power.

 

Yea thats what I plan on doing and I think I can pick up a x pipe for pretty cheap at one of the shops in town. I just want to make sure its alright if I keep them out and run like i am now.

 

Yeah your not hurting anything, you'll just have some better low end with an X pipe.

 

It sound's like you have the same exhaust setup as me. I also installed an X-pipe on my truck but removed it after a couple month's cause it didn't add any power but quieted my truck down too much. If your interested in an X-pipe i'll sell you mine for cheap. It has 2.5" inlet's and outlet's and does not have any rust.

 

how much? And what are you running now? just straight without the rear cats or do you have flows or anything back there?

 

I'm just running straight's right now. I plan on buying an 11" maggie and running my exhaust lightning style. I'll sell the x-pipe for $25 w/o shipping. I can't ship to canada.

 

i am going to check at the muffler shop in the next couple of days cause i think he said he had one for 20 but if not i will take you up on that deal

 

how can you pass emissions with out the cats?

 

You cant, thats why when you have emissions its best to not modify your cats at all.

 

Yea they probably do have one cheaper mine is a magnaflow x-pipe that's why it was higher.

 

do you have any problems with your check engine light comming on? I know when mine comes on due to o2s failing I wont have any power when I push the gas to the floor

 

Rear converter deletes on 2004 & 2005 trucks do not trigger CEL lights due to the rear sensors do not monitor the rear cats, they are infront of them, therefore monitoring the pre-cats only.

 

where would I buy the rear converter deletes mine is an 04 extended cab and thanks for the info

 

You need to do it yourself. Its not legal so you wont find a kit. Check out my experience.
