I’ve got lotsa questions on side pipes.
First my info:
I’ve got a ‘79 L82 automatic with AC. 225hp stock. I’ve saved up $1800 and I really like the look of side pipes. Emissions police are not an issue where I live. I know they will be loud and I know some vette owners can’t stand them after about 20 minutes on the highway…
Right now I’m considering chrome or ceramic coated Hooker super competition side mount headers, chrome Hooker pipes and chrome Cobrastuff.com heat shields. About $1500 total for the parts.
Questions:
How high do you have to get the car off the ground to install the side pipe headers? Can a side pipe system be installed just using car ramps or do I need to have a shop with a lift do this part?
I’ve had the manifolds off once already to coat them with heat paint so getting them off should be easy this time.
Looks to me that I will have to modify the AC bracket to get the passenger side header on correct?
Will it matter if I go with ceramic coated headers and then chrome side pipes?
Do I have to modify or cut the rocker panel molding where the headers exit out the side behind the front tire?
What would you recommend for the muffler in the side pipes? Are there any out there that allow you some flexibility on the volume by just reversing the muffler in the pipe?
What kind of hp gains would I expect from this mod? 10hp? 20?
Will the reduced backflow pressure caused by changing to headers require me to do any engine tuning? (I’m kinda stretching on this question so sorry if it’s a stupid one)
Thanks!
