Hey guys so I'm still deciding on whether or not to buy a Magna Flow X-Pipe to add onto my HKS True Dual setup I have after reading about how restrictive and horrible the hks h pipes were. Would I notice any significant difference in sound in the low rpms? I think my car sounds good as of now but NOT LOUD ENOUGH What're your opinions guys?
Oh and also I can't seem to find a video of this combo after searching the forums and the web. Many Thanks!

 

I started a thread on this subject a couple years ago have run into this situation myself. SEARCH If you like the way your HKS exhaust sounds, you'll love it when you install the Magnflow X-Pipe and the restriction is gone! My restriction was 1/4" on the right side an over an inch on the left. The X-Pipe blends the pulses between the two banks and adds a few RWHP. If you want a louder exhaust add HFCs, that's worth at least 8 RWHP and sounds really....really great!

Thanks Gary! I will def get on it. I have another question.. Do I just buy any regular Magnaflow x-pipe with 2.25 piping or is there a specific product number for these x pipes? Appreciate it!

 

There are multiple videos on youtube of this setup.

 

I just got this done about a month ago and it was well worth it. There was definitely restriction and the x-pipe took care of that situation. If you have the real hks then you will need the 2.25" pipe cause thats what i got. I think the replica is 2.50". Hope this helps.

 

I forgot to add that I didnt know much of a difference in loudness at low speeds except at highway constant speed its quieter since alot of rasp is gone, but WOT sounds great and got rid of alot of the rasp...alot cleaner now and still loud.

 

Thanks! Helped a bunch!
