Absolutely, you better not take it in to the dealer with a custom made what have you... I thought about that after I cut down an 06 K&N intake tube (the big plastic one) and made it fit my 07 without the resonator box. I have a K&N barrel filter in the stock breather box and that in itself wouldn't effect any warranty. I believe the sticking issues with warranties are modifying something yourself. I know it's stupid in this case, mine, hilljobs and others are no frikkin different than any add on kit like K&N, Volant, Trueflow, etc.. HOWEVER, if the dealer or factory wanted to be a ***** about it they could probably win their case if it ever went down that far.

I've kept my accordian tube and resonator box just in case. I also kept my stock exhaust in one piece, just felt like it was the smart thing to do. I'm not at all worried about the Magnaflow dual exhaust being an issue. I just wanted to keep the stock uncut, just in case I ever had the opportunity to sell either the stock exhaust or put it back on and sell the Magnaflow, I figured I wouldn't make much but whatever I got would be better than nothing and storage doesn't cost me a dime.

 

Yea I kept my Rez box just in case. If Hummer Guy reads this what do you think?

 

well,i took it to nebraska this weekend.i got 275 miles on 14 gallons,which was like 19 mpg on the road.thats freakin awesome to me.and i was going 78 most of the way,if it wasnt 78 it was 68,(70mph zone and 65mph zone)....yeah i speed.sue me.....but in my eyes it did wonders,i think when we first got it it got 16-17 on the road.so not a bad deal in my eyes.i do still make them,you just need to let me know so i can get one done.

 

Just got done making my own an instaled it. looks and sounds great. i could tell a diffrence in take of and when i went up hills was not day and night diffrence but well worth the $12 had it made and instaled in 30 min.

 

is it possible to make one of these without welding?

 

I took a 330 mile trip about 85miles was in town and i got 18.3 mpgs take care.

 

Yes just use some jb weld or some thing like that it doesnt get real hot.

 

Kurtis you should take over were hilljob left off and make some to sell. Hell I'd buy one from ya.
Can you post up some pics?

 

Post some pics! I'd be willing to make a purchase from you as well
