im stuck i cant decide which long tubes to get im gonna get the o2 sims and a off road y pipe. i cant decide there is the hooker headers, FLP, SLP, dyna flow, there is also the headers from LG motorsports thanks for your suggestions.

 

The artical from Popular Hot Rodding claims they dynoed a 35 hp at the rear wheels increase from SLP mass-air sensor, headers, high-flow catalytic converters, and cat back. That's 339 hp to the rear wheels with no other mods. That translates to about 390 at the flywheel. That's not bad.

Then another 18 hp from the SLP cam to total 357 hp to the rear wheels. That's not bad for a daily driver that should still pass a snif test.

After I put in a high stall converter I was thinking I might try the SLP Headers with high flow cats.

 

To get lots of opinions, do a search here, www.ls1tech.com and at www.ls1.com .

The only three I would consider are Hooker, FLP and QTP (Grotyohann).
