turbo back exhaust

[X2guy]

is there any improvement in changing out the down pipe. im planning on installing a 5 inch exhaust shortly. Also if i do change out the down pipe which systems allow you to bolt the stock exhaust back up for emissions inspections

If do a turbo back exhaust you will NOT be able to reattach your stock exhaust. I would suggest doing a dp back exhaust then purchasing a down with flange that way you can go back to stock when it's time for emmissions. That's the way I did mine.

Not true, it depends on the down pipe purchased. If the new down pipe has a ball and socket type connection, your factory exhaust will bolt right back up to it. I have a down pipe from Street Diesel Performance. My factory exhaust bolts back up no problem.

so is it worth doing the down pipe?

I thought so. Slight decrease in EGTs and certainly flows better than the crimped stock down pipe.

I bought a flo-pro 5" Turbo back exhaust.. i replaced factor DP with 4" DP but it doesn't have the ball and socket fitting on it.. is there a way to just purchase the lower half of the DP so i don't have to replace the whole thing up to the turbo? so basically i want to purchase the lower half of the DP that will bolt to the factory exhaust. only reason i'm interested in doing this is returning my truck to stock when i sell it / trade it.. i feel like it would be an easier sell or trade in if its stock form.. plus i want to keep my tuner for the next truck i buy..

I'm not sure if you can buy just the bottom half of the down pipe? That's why I purchased the SDP down pipe, because the flo pro didn't have the same fitting. Maybe your can contact SDP and see if he will sell you half? If not your going to need a whole new down pipe to reconnect your factory exhaust. It's definitely easier to sell a stock truck than a modded one.

I guess if I really want to return my truck to stock ... I'll just have to buy one of these down pipes. I really do t have an option . I currently don't have plans to get rid of my truck anytime soon, but I agree... A stock truck is much easier to unload... I'll have to deal with my leveling kit... But stock exhaust is key IMO

I did turbo back, the DP looked like it was going to be a PITA but it was easy, it has a nice size crimp in the DP, what you see under your truck is the outer pipe, there is a pipe inside that one so the true pipe is much smaller, the new DP does away with the restriction and makes it full 4" . I also did the 5" from the DP back with no muffler, I love it, inside that cab its very quiet, out side its not at all what i was thinking it would sound like. I hate the " red neck popping loud exhaust" this sounds great. do it. and you can always put your stock system back on , blots right up to the DP, I got dimond eye turbo back from a member here on this site.

I was looking at the diamond eye turbo back...i found the best deal on ebay and asked if i could bolt the stock exhaust up to to down pipe and they said no. But refered me to the same 5 inch dp back with flange and no dp. Doesnt really make sense that they would have a different flange if you ordered a tb or dp system....guess i will have to call th3m in the morning.
