How much hp from LT headers?

Currently i just have an ebay CAI.

Looking to get a bit more hp out of the small 305 LB9...

How much would full exhaust including LT headers would net?


Is the HP gain worth the money?

I suspect at least half of members on here are running some sort of aftermarket exhaust...

Re: How much hp from LT headers?

if all you have for extra's on the car is a CAI, I would think about 10% hp gain.

Re: How much hp from LT headers?

The ground clearance issues and installation hassles of long tubes wouldnt be worth it on a stock 305. Go with a good 3" cat-back for now, and if you really want headers, a set of shorties is fine for your power level.

Re: How much hp from LT headers?

Dyno Don's headers at top down solutions are a shorty header with a custom Y-pipe. You won't find a set up with better ground clearance. I believe they are 1.75 inch primary as well. Depending on your budget, the price may be steep. I have hooker long tubes, I am apprehensive about speed bumps.
