Today i had my HKS Hi-Power muffler installed with costum 3 inch piping and my ultimate racing 3 inch test pipe. I must say it has a nice low sound but when you hit it, watch out opens up. also the minute i had the guy install the test pipe he put the 02 sensor back on had to take it out a lil bit. so no wires had to be spliced. as i started it up no CEL light. i also Highly recommend the ultimate racing test pipe if you want to get rid of your cat. cheap and works the best imo.

 

Which Hi power did you install? 30th or regular? Thinking of getting one just installed a Magnaflow TI last week and it's pretty loud looking for something quiter.

 

regular Hi Power just the muffler. looks and sounds nice. has a burnt tip.

 

The muffler HKS uses in their Evo hi power system necks down to 2.25 or 2.5" internally, was your universal muffler the same way or was it actually 3" id?

 

How did you get the burnt tip? thought only the carbon TI has the that tip.

 

good ****!

 

to be honest i dont know the actual diameter of the muffler, but i purchased from lanevoVIII.com they sell the mufflers by themselves on there site. when i got the muffler it came in a box with HKS tape on it. i checked out the muffler i was confused at first because their was no etching on the tip or anything saying HKS. so i contacted them and they told me that not all of there mufflers come marked with something saying the HKS name and you can tell thats an HKS from the finish and the way it was made. i also contacted the people i ordered from they told me the same thing. so its possibly a special one. but i did just buy the muffler.

 

hey, website doesn't work.... www.lanevoviii.com ?

 

sorry about that http://lanevo8.com/ is where i purchased the muffler.

 

have you raced the car to see if it makes as much of a difference as you say? or do you dirve the car regular

 

i've pressed it during my days off and when im on the turnpike, i felt it start picking up about 3 grand feels alot better without the cat. whoever said you dont feel a difference without a tune is wrong. i felt it and i had a friend who rode in my car when it was stock and now that i got the exhaust setup on it he told me it feels quicker then last time also.

 

i'm the proud new owner of an evo8mr i was browsing through and i saw this

he welded the o2 sensor on the test pipe?

 

I have the same set up. Exact same thing. I hope that the cops dont stop you like they did me. I got stop three times for that exhaust, beat two tickets so far. It sounds crazy when you open it up. I had my freind drive my car and when he steped on it I heard it half a mile away.

 

nope, the ultimate racing 3 inch test pipe comes with a hole for the 02. i had it put on about last week or so i believe and since the day it was put on still have no CEL light. i recommend their test pipe very much. its cheap and it works wonders.
