I'm going to be full bolt on soon. Have roush axlebacks installed now and soon will be installing the boss mani And JLT cai. After that will be installing stainless works 1 7/8" headers and their merge spike o/r x pipe. Then finally a custom dyno tune! I have a buddy that is full bolt on with all the same mods except he has the kooks 1 3/4" headers and x pipe. and he has a dyno tune from the same shop as I'm going to so I should lay down a lil more than he did. His stock dyno was 372 whp and the after results were amazing! His dyno sheet after the mods and tune was 474 max whp! I didn't believe him at first but when I saw his dyno sheet their was no denying his claim. When my work is finished I will post my results for everyone to see. The tune he has is very agressive.

 

Also with the 3.73's , LT's , o/r xpipe , and a good tune u should no notice the low end torque loss with the boss mani at all!

 

Cool cool, im not going to go with a really aggressive tune as this is currently my only car and can't afford to mess anything up. Decreasing the back-pressure always help to keep the torques so that's why I was looking at exhaust setup to go with intake and mani. Have to keep it balanced between a DD and car to take to the track/strip. For now that is...lol

 

Just get a tuner from bama u will have free tunes for life and there tunes are mild and safe. And go a speed shop and have them dyno tune ur car then just have them store it on the tuner and u can run the mild tune and still have ur custom dyno tune for when u want to track the car or just play

 

Make sure that the shop u go to has a good rep for the work they do.

 

Yea ill be going to Lamotta performance for a custom tune. He's been published several times in the mustang and 5.0 magazines. They used his car for the canned scm tunes and he was published in the mags for the review of the boss mani on a 5.0.

 

That's cool friend of mine went to Stang hi in baton rouge la and got dynotuned he is full Bolton and showed gains of about 98whp with there tune. Thats unbelivable! That's where I'm going for my dyno tune will post when I get results.

 

Have a magnaflow off-road x w/ only 3k on it if anyone's looking. Near chicago

 

Why did u take it off?

 

Ended up going with stainless works longtubes. Got excited about modding the car when I got it and didn't think I was going with lt's.

 

Got ya thats the set up I purchased SW's 1 7/8" primaries with merge spike o/r x pipe 3". Going to install it in about 4 weeks cuz I'm doing my boss mani and CAI first. Will be installing the boss in a few days. Me and a buddy that's a mechanic are going to do the install. Can't wait!

 

Ur gonna love it. Lotta mods give u a little hp at a time. Can't really feel it when u drive it. First time I got in the car after the lt's though I totally felt the difference. Awesome!!!

 

Here's some good instructions for the install...

Once I'm done with the work hoping for some solid results!

 

Hi

I have 11 5.0 with borla atak with x-pipe, any one installed xr-1 headers?
Any opinions?

 

IMO you would be better off going with stainless works or ARH as they have larger primaries to accommodate future mods! I personally went with stainless works

 

I have the Borla ATAK catback w/ x-pipe and I'm also looking into some LTs... From everything I've seen and heard, the ARH 1 7/8" LTs are the way to go. The xr1s will be a little more restrictive

 

Does the ARH have the slip fit 3" clamp in cat delete pipes? Or is it just the headers and xpipe with no cats?

 

some come with catted pipes, u have the option of cat less xpipe

 

What would the sound be like if i installed arh headers with removing catalyzers and installing borla atak cat bak?
