exhaust

OK so I have determend that I have a SLP exhaust from the axle back. Would getting some kind of aftermarket pipes from cats back give me more hp? And if so, what should I go with? I love the sound it has now, would it change the sound from what I have now? That's not saying i wouldn't love the new sound either. Advise is appreciated!

Do you mean a mid pipe? It will change the sound of course but just changing the mid pipe won't give much if any gains, but it will make it louder.

What it'll sound like will depend on what kind of mid pipe you get. O/R or catted, X or H. Off-road will be the loudest. X pipes are more raspy, race car sounding. H are more deep, old school sounding

Most of the HP gains from exhausts are from the heads. If you put in LT headers, you'll probably gain 15-20 HP but debatable if it's worth it.

Pretty much. The only logical reason to swap out the midpipe is if you plan on putting long tube headers on.

You'll gain 0 power from an exhaust swap unless you do longtube headers. And they really aren't worth the money it costs to do them.

If you do Chang out the rest of your exhaust... X pipe gives more of a mid range power gain. H pipe will give you more bottom end gain. I personally have Basanni off road X. Love it.

X vs H is little/no difference. Biggest difference is sound.

H vs X pipe is all in ones preference. Sound, air distribution and application dictates most application choices. The HP gains between the 2 are relatively the same. Sound is different, which also takes into consideration what the other components that a person wants or has to make up the whole exhaust. I have personally witnessed 2 of the same vehicles with the same exhaust components and they sounded totally different due to the condition of the drivetrain. One was well kept and the other being ragged on to the point of no return. I opt always for a H-pipe myself due to the old school sound. But that is just my opinion.
