"The ecoboost convertible has a support bolted in the rear part of the car (very easy to remove).This added support is the reason you cannot use a 3 inch exhaust.Because of the tight fit you have to make sure that everything has the correct clearances before you tighten everything down."

Reviews
"Did not come with the spring-loaded nut and bolt sets for between the cat and downpipe so there is little to no flex in my exhaust right now which may lead to problems eventually if not fixed. The Dynamik header/downpipe combo(or pretty much any new header/downpipe for this car) replaces the existing exhaust manifold/cat(cat is mounted directly to exhaust manifold on this car) and also the existing downpipe, and this Spec-D catback is designed like any other...assuming you will be running a test pipe or under-car cat to put between the new catback and the new header/downpipe."
"Sounds fantastic."
"That being said it sounds like a 130 dollar cat back exhaust."
"Did not hold up long before the welds broke and the system was useless."
"1994 Honda Civic 4 door."
"Great muffler, not whinny like some of the others, and offers good air flow."
"Bought his for my son, he have a 2000 Honda Civic scoop and he LOVE the sound."
"The sound is great and my car's performance has improved after having installed this system."

Best Automotive Replacement Exhaust Heat Shields

DEI 010127 Titanium Exhaust Heat Wrap with LR Technology, 2" x 50' Roll
DEI Titanium exhaust wrap, with LR Technology, is made from pulverized lava rock and stranded into a fiber material and woven into a proprietary weave. The alloys used in the production of titanium exhaust systems tend to be thin and are designed to dissipate heat quickly. By wrapping the exhaust, the additional heat can make the titanium alloy turn brittle and prone to premature cracking. Reduces temperature & vibration breakdown. High resistance to abrasions, oil spills, temperatures and vibration breakdown.
Reviews
"Supposed to regulate the heat to slightly increase performance... who knows if it does. I wanted to run these pipes without the heat shields since the bands snapped and rattled around. Results: I like the look and the heat seems to dissapiate evenly throughout the pipe now."
"Though it is still very warm it will no longer burn you."
"In my opinion, this is a must for RAM 2500 trucks to insulate near your transmission to keep your transmission fluid temps down."
"One other thing to note from my research, one of the cautions with exhaust wrap is that with the temperature difference on where your wrap ends up ending, there is a possibility of the exhaust pipe cracking or becoming very brittle."
"With a couple hose clamps and about 10minutes I was able to completely wrap the midpipe on a 2006 Honda CBR600RR and what I feel to be very nice results."
"UPDATE Oct 16th. Worked excellent for 600 miles, till I saw what the redirected heat was doing to the rest of the exhaust system."
"I used this to wrap the exhaust on my 2014 Yamaha Grizzly 700."
"I have an RV that had large heat shields screwed into the exhaust pipe under the chassis to protect the plastic storage boxes from heat."

Best Automotive Replacement Exhaust Extension Pipes

Lisle 17350 Pipe Stretcher Kit
The pipe stretcher kit stretches pipe up to 4-1/4 inches including stainless steel. Expands all types of exhaust pipe, including stainless steel, from 1-5/8 inches to 4-1/4 inches in size.
Reviews
"I wanted the enlarged section to be as concentric as possible so I would expand a little, back the tool off, rotate it slightly, and repeat. The short Lisle video shows the expansion without moving the tool like I did and you could see there were gaps from the expansion of the tool. As an aside, Amazon has cheaper alternatives that have 6-8 sections that move out (not 4 like this item), but each of those tools had various complaints about the strength of the tool or its effectiveness on thicker tubing."
"So I'll give this 4 stars at the moment since I'm not ready to toss it under the bus for that until I prove otherwise."
"Works wonderfully, I have rented this product before for specific jobs, but this one really out shines the rentals!"
"Pipe stretcher works very well even with 4" pipe."
"This works exactly as expected."
"Tired of buying cheap pipe strecher, i try this one, it hold up a good impact torque and streach pipe with no effort, and the pipe seems very round."
"Requires significant torque to stretch 16ga T304 tubing, but easy to use overall."
"Used to expand converter pipe on a 2000 Sebring to reattach it to resonator pipe using a 2 1/8 to 2/14 adapter."

"fixed the "tighten fuel cap" and turned off the check engine light on my 05 chevy silverado. cut the OEM line off (no gas or fluid leaks out). i drove it a few times on short trips to see if engine light would turn off. the light stayed lit but i didn't get the tighten fuel cap beeps and warning. years ago when it start warning me, i bought a new fuel cap and that didn't help."
"When looking at the back of the Suburban, the Evap Solenoid is directly above the rear axle just to the right of the differential. Install was as simple as reconnecting the hose, wiring harness, and clipping it back on the mount."
"Because cutting the hose would have made it too short, I removed the canister and hose assembly in order to disconnect the hose without cutting it."
"The hose fitting will come off of the old part it has two barbs that keep it from allowing the fitting of the valve to come off."
"This will replace the factory one without running tubbing to the front and adding a filter."

"You need to replace this part on the head once per year even if you do not use the head that often."
"("Heads" - toilets). The same one you'd get at West Marine - for about 50% less."

"I used this in my Raritan head."
"Just as advertised!"
"This time I went to West Marine and opened every single package, holding each valve up to the light until I found one I could see barely any light through. A valve you can see light through is a valve that will backflow too."
"I don't think it's my installation, but these valves both leaked within a month of use....and they were not used very much."
"Last less than a year...but we're stuck using them if you have a Jabsco head."
