Hi friends,

I am running hooker long tubes and Flowmaster 40 series straight pipes and I am thinking about installing a H-Pipe to make it sound a little bit better. I have read many different thing about that but I am not sure about what to except.

Do you have some before/after videos?

Any recommendations on the H-Pipe to install?

Thanks,

There are many variables involved in the sound. One that is rarely considered is pipe size. If the pipes are too large, you will get a lot of popping and snapping. If the pipes are too small you will get a little more mellow tone, but sometimes hear a "whooshing."

In the case of pipes too small, an H pipe will make it sound more mellow. In the case of pipes too big, it will have very little if any difference in sound. In the case of correct pipe size, it will make it sound a little higher note, that is it will sound like a little higher frequency.

Again, there are so many variables, you just don't really know for sure until you try it.

i have before, but if I make an after it's no real comparison as my engine changed.
however I found the sound to become more 'balanced'. I really don't have a better word for it. if you stand right behind the car You hear one V8 instead of 2 rumbling inline 4. without hpipe you can hear two sides of the engine, not so much with the Hpipe.

Straight pipes are LOUD. I had 2.25" straight pipes and Dynomax Superturbos and my car was very loud. I went to a 2.50" with an H-Pipe and 40 Series Flowmasters and like Kalli said the car sounds more balanced and it's a know fact that an H-Pipe will increase HP.

I think you'll be happy with the H pipe. It definitely makes the car sound more balanced or smoother.

If you want it to sound more mellow get rid of the Flows and go with Magnaflow or Dynomax Ultraflo.

Your best bet for an H pipe is to take it to a muffler shop and have them add one. It will fit much better. Most of the prefab ones don't fit that well. I know mine doesn't. I am about to get that part of my exhaust redone.

What size exhaust are you running? If your running 2.25-2.5 inch just get a 2 inch pipe ran across between them.
