ps.. great time to flip the sway bar or replace it...when those rear subframe bolts are out.
Sure, get Poly Lowers all around...that'll make it not hit.
Headers and a few other small things were a 29 WHP gain with a tune on a bone stock GT.
High Performance Pontiac did an add on the SLP Headers/Catback/T-Stat/Plugs-Wires/Intake/Tune on a N/A car...30~ WHP is pretty noticeable on a car that makes maybe 160~WHP stock.
Rynoman made 240~WHP with a pulley and a downpipe back in the day and a junky tune. Yay, numbers.
Which is like...bone stock with headers?
Since they are rated @ 240 CHP/280 CTQ from the factory
