They bolt right on and didn't do the install so I don't really know how they looked before.Do long tubes bolt up to the exhaust or do you have to cut the pipes?Also how much more do they hang down then shorties?
I would be careful, if you haven't added any fuel you are definitely running lean.Flowmaster supers 40's and I'll get a dyno after I get a tune. It's already a big difference in the speed.
I did it all via email with johan. You send him all the mods that you did and 1 log file and email the info to johan he'll email you a tune. Download the tune (I renamed mine) and using a computer drag the download into your tune folder after you put the tune on you car send him another log file.Man why did I look at your post! Now I really want this done
09 Challenger R/T brings up a good point although it raises some questions like if you have a diablo tuner can you just email someone with mod list for a correct tune or do you have to take it to a shop.
I have a 13 RT with the STP so it sits a little lower than other RT's. If I go over a speed bump too fast ill scrape the LT's.Do long tubes bolt up to the exhaust or do you have to cut the pipes?Also how much more do they hang down then shorties?
Stainless works longtube headers and I had a friend do it with my help. It took 4 hours 1 day and about 3 and a half to 4 hours the next day to finish.Sounds great! What brand of long-tubes did you go with? What did the installation run you, and how long did it take?
It actually increases low end torque, on the 5.7's at least.Did the power band shift to higher RPMs? Often times when people put long tubes they feel as if they've "lost" low end torque, when in reality it has just shifted up the power band.
Just curious about this
