Alright just to lay out the plan I plan on getting LT headers for my T/A and then running a true dual 2.5" X-pipe exhaust and no cats, the car is stock so I know this kinda might be overkill but I figure any mod I add after this will benefit from the true duals. So here's my questions, I'm a newb so sorry there are so many:

1)If I go with kooks LT's how much ground clearnce would I loose?

2)I plan on putting on UMI 3-point sub frame connectors, will this cause a problem in routing the true duals?

3)Will the true duals/headers drive my knock sensor crazy? If so is it better to get an LT4 knock sensor or to just have the stock one desensitzed/tuned?

4)Will the car run like crap until I get a tune? Would o2 sims fix this if so?

Thanks for taking the time to read all this and any help is appreciated. Like i said I'm a newb and trying to figure all this stuff out

 

1) Kooks headers still have excellent ground clearance. No worries here.

2) Mount the UMI 3 points before you have the exhaust fabbed. That way they can work around the subframe connectors and adjust as necessary.

3) It is a very good idea to get the LT4 knock module. Also have the knock sensor de-sensitized when you get the tune. Any decent tuner like PCMforless suggest the use of a LT4 module, and know what they are doing.

4) Just an exhaust and headers will not make your car run like "crap". It will run better once you get a tune specifically for all your mods and the LT4 module.

Hope this helps.

 

Cool thanks for the info ! I'll go get a LT4km from the dealership tomorrow. Sounds like I'll be post-poning my exhaust work until I get my SFC's and maybe a few other suspension parts while i'm at it.
Thanks for the input
