E63 Resonator and Secondary Cat Delete
 

Finally going to bite the bullet since this procedure is reversible if I don't like it. I called HMS Motorsports and they say this will cost $650. Is this a fair price? This seems kind of steep, but I hear they are a very good shop.

I did a search and couldn't find any recommendations for a muffler shop in the Orange County area. If someone knows of someone that can do a good job who is reasonably priced, please chime in. I am going to embed a video of what I want my E63 to sound like.

I think it's a little steep on the price, maybe $100 to much if that.

Go for it, I guess living in So Cal it's going to cost more. I paid around $400.00 for mine, but I live in Oklahoma. Its been a long time since I lived in Cali.

I highly recommend HMS. They do top notch work! :y

I don't know how much it costs to delete secondary cats, but my resonator delete cost $60 at a muffler shop. Another $600 for a secondary cat delete sounds expensive.

i paid $80 for resonator delete, got quoted 250 for cat delete including magnaflow x pipe.

Where in oklahoma ? never see u around here. Im in okc.

I live in Lawton, stationed at FTSill. I dont get up to OKC very often.

yeah it really shouldn't cost that much

My cat and resonator delete ran $550.00, 3" stainless steel all the way, and a custom x pipe. I wanted to retain the bolt on/bolt off, of the stock system.

How does it sound? Do you have a clip for us to check it out :)

No, but I need to make one. :naughty:

How do you like it? Is it super loud in the cabin?

Greg

I had my resonator taken out the day I picked up the car. It sounds unbelievable!! Sounds even better than the w212 e63. No sound clips yet.

Why the X pipe and not just straight pipes? to maintain some back presssure and exhaust flow or ?

Went ahead and took my car down to HMS Motorsports in Westminster and got this done. I removed the resonator and secondary cats. After 3 full days with it now, I have to say it was money well spent! At first, I was kinda disappointed because it wasn't crazy loud (while in park). Then I put the car in gear and drove it around. THIS IS HOW THE CAR SHOULD HAVE SOUNDED FROM THE FACTORY!!! Yaye, finally! I get great exhaust sound throughout the whole power band. It is also pretty quiet at highway cruising speeds and it dosesn't over power the radio/blue tooth. Great mod, and thanks HMS (Edison and the boys).

Next month....RIMS!

I concur. Quiet at idle and cruise speeds until it down shifts pass 2500 rpm through red line. It sounds like a monster from the outside. No power change that I can tell only an intoxicating sound to bury the throttle.....I think it actually sounds meaner than my Vette....

Resonator delete with x pipe
 

having an X-pipe or H-pipe in place of your resonator is a bit of a waste. it is pretty far down the exhaust stream to effectively provide scavenging. in addition the secondary cats have a built in H-pipe. if you remove your secondaries and have removed your resonator you'll have a pretty beastly sounding E63.

I have my resonators deleted and just had them run straight pipes for basically the reason Barry said. Paid $150 to have it done at a local muffler shop.
