If you are looking at the 4 inti 1 pipes ( as shown above) you will need the 63" pipes. If you are looking for the shielded single pipes then you will need the 60" I think. You will need to confirm where the measurements start and stop from the adds on the single style pipes.

I was also thinking about doing these, (sorry to partial thread jack but) how do you install them to the headers?

NHvette - I used to live in the nashua area, but I moved to mass. I used to live off exit 4.

If you are going to use Patriots with headders then use shorty headders or I think Hedman makes a set that turn the pipes out to the fenders instead of going to the back. Otherwise you will have to make a 180 and a 90 degree bend to get the exhaust routed from the collector to the pipe inlet. Do a search for side pipes and there are some pictures posted of the last set-up.

I wanted to use Headman headers ( already have them) and when I measured from rear of front wheel well openint to rear of door, 60" seems long and 50" seems to short..
A question about the 4 in 1, don't they get very hot for getting in and out of the car?

Can't answer about the shielded ones but YES the 4 into 1's get hot. You won't get burned but twice if you are a slow learner.

I put them on my 77. Don't listen to the people who say you will burn yourself..........you know that they are there, I haven't burnt myself in the 8 years since I put them on. I do recommened reminding your passengers if they have not been in your car. The exhaust DOES NOT go in the car when you are at a light either.

Good luck...........sounds good already!
