Frpp shorties - saw a 20rwhp increase with them with everything else the same. IMO freakish results for shorties.
mid pipes used.
Stock - exhaust leak was driving me nuts and was waiting on new or mid.
Prochamber - first OR midpipe I had, but would not clear DS loop so I had to replace.
mac OR hpipe- Loved the sound but wouldn't stay sealed up hence the stocker going back on. In hindsight shouldn't have bought it used even though it was dirt cheap.
Pypes OR xpipe - clears DS loop, was cheap, and seals up.
Now what would I change to Flowtech or hooker LT's ( I know they clear for tranny removal) and prolly a custom shorty hpipe.
