Default X-Pipe Only mod?

Has anybody done an X-Pipe Only install?

I only ask because WCC has a big sale on those now, and I could use a few more horses, now that the pavement is hot and I am running 305 Nittos which seem to want to soak up all the engine I give them and beg for more.

Thanks and Happy Memorial Day!

I did the x-pipe only. I might give you a couple horsepower, you really can't feel it. I did it to get rid of the exhaust jingle and the popping upon deceration. It will also quiet up the exhaust 3 to 5 decilbes and also smooth the exhaust flow.

I wouldn't do it. Just get headers with high flo cats. You will pick up a solid 10-15rwhp with a tune, and a good base for futre mods.

no need to do an X-pipe without LTs and highflow or no cats.

not all x-pipes are the same either. The smother the X transition allows exhaust gasses to escape quicker.

However, must mufflers will negate almost any gains from an x-pipe unless your running straight pipes or something like Borla Stingers

Thanks for the advice. I think you are all right, that at or near $300, alone this mod struggles to earn its keep.

Have a great holiday.
