Full straight pipe. Yay or nay?

Taking off the cat will not benifit you much as people have said.
I ran a pipe with no cat and just a muffle and it was annoying.

[Hey_You]

Do NOT straight pipe your car. Stupid loud. In Fact, RETARD loud (no offense to those who are or have close persons who are mentally handicapped). But you have to be an idiot to have a straight piped car for anything other than a track car, and I hate every minute (almost) of my waffleswaffleswaffleswaffleswaffles assed m10 and it's straight pipe to a Vibrant muffler. Only time I love it, is through a tunnel above 4k and it sounding like a street bike.

Its very loud straight piped, painfully loud.

So is it better to keep my cats or get a resonator?

Keep the cats srsly.

I would seriously hate being in a car with no cat/muffler. Would irritate the shit out of me during daily commutes. Unless you have a twin turbo s50 and can get away with the loudness, dont.

[Hey_You]

I retract my statement, just run zoomies out of your hood

[nando]

no.

I take the cats off of every car/truck i own. I ran my e30 with no cats and just had a set of glass packs. Yes it was VERY loud! But thats what i like. The m20 isnt a high breathing engine, so you most likely won't feel a differance, but also does it help that its trying to breath through that stink can?

I have a cat delete, straight mid section on my M30-E30. I have a stock 325i muffler on it though so it's not loud at all, barely louder than with the cat. This is the way the european ones were. Their M30 535i was rated at 10hp more than ours so I figure it helps a little at least. If you have anything other than the OEM muffler though I think it would be very loud.

straight pipes fo life foo! Both my cars are decatted and mufflerless. My E30 has a custom exhaust I built that goes from 3" to dual 3.5 for 21" long exhaust tips. I think it sounds good.

I took my exhaust pipes out of my muffler and attached two Cherry Bomb glass paks, The pipes slide right in with no problems. The sound is great, very throaty.

Turbo quiets the exhaust note down and takes away the rasp

i have no cat, no rasp. 1 resonator, one magnaflow. Very loud

keep the cat and save the environment, keep the muffler and save your ear drums.
