Had a Road Tune

[evoto86]

Got a Header and Overpipe with a Road Tune a few weeks ago, will adding a high flow catted FP do anything except noise ? im guessing a tune wont be needed since the car is already tuned for headers.

Probably nothing.

I was told it can add a few HP at peak (I assume peak flow) vs stock with an Ace350. I ran stock FP while waiting for a resolution on a design issue on my 3" (with HFC). Ended up fixing it myself after hearing nothing from the vendor. No tune adjustments needed (perhaps within the safety margin on remote tunes).

In my experience the swapping the stock front pipe for a Nameless HFC front pipe made the car louder and felt sharper on part throttle at lower rpm. Full throttle high rpm felt the same to me.

Very little difference. Maybe a bit louder. No need for retune.

I wont bother in that case, probably better to put money towards bigger wheels and better tyres.
