From headers to all pipes, and exhausts. With just the basic bolt-ons, what brand and what would be the best way to make power.

 

Here's my take. The most restrictive part of the exhaust system are the CATS, so changing those alone would net you some noticeable gains. The most restrictive part on the intake area is the Plenum, so getting a modified plenum would benefit you there as well.

With that in mind, you can't go wrong with the current HF CATS + Plenums on the market. There will always be endless debates as to which ones are better, but in the end, they pretty much produce similar gains. So go with what you like.

 

aps parts are the most practial and well engineered. they are realistic. REally good, they make exaust, plenum with good strut bar and test pipes(really good ones, they are straight through)

 

oh and ecu reprogram is a must to retain hp gained from bolt on af mods.and aps exaust allows you to mount factory rear muffler air guide to mimic factory airodynamics.

 

you're right APS does make some good stuff but as far as i know (according to their website) most of their products are not available yet

 

Here is how I made decent power with bolt-ons minus headers cuz the install is expensive and Im going FI down the road:

Stock dyno 238 whp 239 ft lbs

With a JWT pop-charger, Crawford plenum, UR crank pulley, test-pipes, Injen exhaust and a technosquare ecu (i needed it cuz I was waayyyy lean) =

262 whp 252 ft lbs

So 24 whp and 13 ft lbs with gains from 2000 rpm to past the stock redline....I still have a 350 EVO TB to add to this mix, so probobly mid 260's with no headers.
