It's around 100.00 monthly not too bad, but I used to pay 85.00 for my 2008 C6.

 

Have you hit the 1/4 mile yet?
If so what were your times and did you adjust the suspension?
Thanks,
Dylan,

 

Local track is closed for renovations, hopefully before the end of the summer

 

This.

CAI/Tune is hands down the best bang for the buck on a new 5.0, GT or Boss. Should be everyone's first mod apart from tires.

X-Pipe comes in second.

It's not that headers won't give you gains. They absolutely will. But for the cost of them, the hassle of the install, and the fact that they will leak at some point in the future, it's a question of cost/benefit.

 

I agree with the tune and CAI being first.

As far as your opinion on headers, I don't. When you get well engineered/higher quality headers and have them professionally installed, even though on a Mustang they are pathetically simple to install. They will last as long any stock exhaust system without leaks. I only use American Racing headers on all my personal cars and customers' cars and we've never had header leaks. On a 5.0 untuned I personally saw a difference of over 25 rwhp.

 

I have had numerous modded cars, old and new, and invariably after a couple of years the headers would start leaking where the flange bolted to the head. Replacing gaskets/re-tightening bolts, etc. would help for a little while but not for long. The issue is headers are never made out of the same material as heads (mild steel or stainless steel vs cast iron or aluminum), flanges are thin, and eventually the unequal rate of expansion during heating/cooling cycles warps the flanges.

Even Kenne Belle has said they do not recommend headers on the GT500 or other FI cars because the leaks that are guaranteed to develop wreak havoc with tuning A/F ratios at high boost.

If you don't believe me or Kenne Bell, just Google "header leaks". 4,460,000 results returned.

 

"Moon landing fake" = 1.1M returns. Its true!

 

 

okay so if long tubes will not net any benifit then why did a Ford Engineer state "We would have used long tubes but could not push the cats any further back"?

 

You seriously believe we landed on the moon? It was all staged out in the desert in Arizona.





















j/k

 

No one in here is saying you won't gain any horsepower from long tubes. Obviously you will. What I said was when you look at a gain of 15-20 hp versus the cost, hassle of installation, and headaches down the road from leaks that IMO they're not worth it. Definitely not where I'd start with mods anyway.

 

I say, go for it and let us know how it turns out.

 

That is what I have in mind to do
Also a Cai and Tune
