Is there anyone with an m2 axle back and gotten back fire?? Its no fair that every axle back gets some, if you do get those pops on downshifts let me know your setup!

 

BACKFIRE = BAD!!!

Back fire is really just your car running really lean and its dumping fuel. Some people get it by running an un-restricted straight pipe exhaust but then you lose HP. Our cars need a bit of backpressure for optimal HP

 

Anyone know a place that has this setup in stock? Everyone appears to be sold out.

 

No...

Haha, yeah. I have an F Sport exhaust on IS250 = , and then I thought I can save money with M2 on the IS350 but = . You pay for what you get really. F Sport is millions times better lol.

 

Has anyone paired the m2 with anything else other than a resonator delete? I'm thinking a manga flow resonator with both secondary cats deleted? Any thoughts?

 

@Flattire Pair M2 with Megan Mid Pipe sounds better or pair it with Invidia mid pipe to sound even meaner with some drone though.

 

I got this exhaust off ebay for $275 but imo its better to wait for a used f sport or name brand exhaust. About a week ago I saw a used f sport exhaust for $450 and it sounds so much better than the M2. The M2 sounded okay. I would get the M2 over the tanabe but if you want to wait for a good deal on the f sport exhaust do it. It's worth the wait. WIth the F sport exhaust there is also no drone in the cabin.
