I wanted to know if there is any clearence issues with Longtubes and Mid-length headers....I know I'm getting sportlines, But deciding on which headers.

Also, I got a set of TT2's w/17x11 outback...I wanted to know if it will rub on the inner fenderwell with some 315 tires...

ThanX for any info...

 

MAC Mid-lengths should be fine, but I will say that longtubes might be problematic if your driving route includes some rather high speed bumps.
As for your wheels, it is usually hit or miss with the F-bodies... Some people have gotten them to fit with no problems and some people have had to do some modifications to get them to fit without the tire rubbing. Just put them on, and if it rubs, then get it taken care of.
Also, why do you want to go with the Sportlines? I believe they are a terrible choice for F-bodies since they lower so much without having enough spring rate. They will be especially lousy if you plan to use them with the stock shocks. I would look at some coil-overs if you can afford to pay an additional $200 for them. Good luck.

 

Thanks man...I'll check the coil overs out...
