Sounds real good! Do you have to re-tune it, or any cel lights come on? I installed a lower intake spacer and gained great torque after my last exhaust job.

@robb15033 on these cars you do not have to re tune it for the exhaust, but with the long tube headers you WILL get a CEL because of having no cats, so with a tune you can turn off the rear 02 sensors, and that cures the code. all the code says is your 'cats' are bad, but you wouldnt have any. i also have a lower intake spacer and i love it, i felt the difference

Did you have a backfire problem? I did this exact system and it just started backfiring right away

[turtleslow]

@zachm17 no i did not have a backfiring issue

@parkermcadoo yes pacesetter also has a set of longtubes for these v6s, i havent seen them to comment on the quality of fit, but i have heard they may need some fitting. but i have also heard that about the MACs. and true you do not need an H pipe if you can have some pipes fabbed up, the sound is a little different than an H pipe, just personal preference

What did you do to have the rpms show in the tac? I really liked it

[parkermcadoo]

@lizardman2150 you can get longtubes from pacesetter for right under 200 and you dont need the h-pipe since the v-6 is an even firing motor you could just do divorced duals like i am :D save some cashhh since im in the same boat as you

@turtleslow hell im moving to michigan then LOL damn, sounds nice tho!

[turtleslow]

@lizardman2150 my exact setup is not legal for most states, i do not have catalytic converters, and also it is illegal to not have tailpipes. my exhaust ends at the muffler. here in michigan i can get away with it due to we dont have emissions testing

@lizardman2150 thanks for the comment, and to answer your question, i payed 260 for the longtubes, 160 for the H pipe, and 140 for two flowmaster 40s. i dont know how much shops charge to put them on, i installed them myself

[lizardman2150]

is this street legal??????
